- Alice Roberts, Professor of Public Engagement in Science here at the University, talks about how we are evolved beings, why natural selection doesn't create perfection and our latest Birmingham Heroes campaign: 21st Century Bodies.
You can find out more about all our latest Heroes and their research here: www.birmingham.ac.uk/research...
Everything this woman does is fascinating! Could listen to her for ages!
There is no such thing as Evolution: you have been conned.
@@RevRMBWest Hasn't religion been conning us for Millennia. The scare tactics of, " if you do or don't do as we say, you'll go to hell! " It's like parents who tell their children, " if you don't go to sleep, the boogie man will get you! " Total, brainwashing, ballony!
Gosh, I've just had a rare experience on TH-cam. Someone has talked to me for twelve minutes as if I'm no more or less than an intelligent adult and as if I can absorb information without the need for gimmicks or force feeding. Superb.
Stephen Paul That’s why she has the job she has.
Alice roberts is one of my favourite living people.
"We're not created, obviously". Perfect statement.
@Edward Evans God of the Gaps?
@Edward Evans If replication of DNA is imperfect (which it is), then evolution will occur. That's just a logical inference from the natural selection of advantageous mutations.
If you want to claim the origin of life (the first self-replicating molecule) as having been created by God, then that's up to you, but be wary that the RNA world hypothesis is developing very nicely, along with other hypotheses. An interventionist god is continually demoted by new discoveries.
@Edward Evans What is a "divine creation"? As long as you don't confuse it with a God of some sort or anything to do with one of the 2,000 human created religions.
What she means is that humans have not been created. No one can explain what the origin of this singularity is. Nor can anyone prove scientifically and empirically that God exists. She is clearly not making fun of religion or the Devine, so stop using that statement as a way to make fun of people who believe in God. And if you do believe in God, then don't put your life on the line and make up an argument. So, again, to say that humans have evolved, not been created, is consistent beyond reasonable doubt. And should not be milked to get angry at each other.
@@fakechloe207 WHAT ?
People like Professor B Cox or Professor A Roberts are two of our British intellectual icons. I daresay other countries have their public pedagogues and I wish I could speak other languages so I could be more familiar with their work but I think Cox and Roberts fly the flag for British public scientific engagement.
Dawkins is also a great orator and writer, even if he uses satire. Whilst Cox and Roberts are more friendly in their countenance, Dawkin's style worked very well for me.
Is she not so lovely. And that voice. Will definitely be watching and listening to more. What a beautifull way to get an education.
I love Dr. Roberts energy in education for us masses. Looking forward to learning more with all future projects.
Thank you Alice superb as usual.
Just catching up on Digging for Britain Series 11/4. Wonderful presenting as always from Dr Alice Roberts.
Professor Alice Roberts!
You are a brilliant presenter and have a great way of explaining things that makes learning a real joy .
She ALWAYS holds my attension, while listening too.
Professor Roberts, I am a fan who is fascinated and happily informed by your presentations of various topics; you are a ray of light, please continue digging deeper
I love the fact that the laryngeal nerve in a giraffe goes 8 feet down its neck, loops around a blood vessel and then goes 8 feet back up again. Brilliant design! If I had a chance to redesign MY body, I would have not had the urinary tract go through the prostate. Just saying...
@Steven White except nobody is attributing the design to any one being. In fact, the existence of poor design only further proves evolution
i'M CONVINCED THAT IN THE NOT TOO DISTANT FUTURE, SCIENCE WILL PROVIDE THAT OPTION, AND CORRECT NATURES MISTAKES.
The most interesting 12 minutes
I’ve passed for quite a long time. Thank you Alice😎
I find both Prof Alice Roberts and Prof Brian Cox very easy to listen to.They both have a very accessible way of breaking everything down into chunks that are easy to digest,always coming across with a natural enthusiasm for their subjects.I will check out the book.Thanks for posting.
This is wonderful. I'm in the process of finding her videos on TH-cam and saving them to go back and watch again.
I always lean something whenever I listen to Prof. Roberts. I suppose I shall now have to go and buy her book.
Prof Roberts is drop dead gorgeous
I would redesign toes so that they're more robust and less likely to be damaged. I did see the 'new' Alice Roberts' and it was an extraordinary sight, the marsupial birth was a great addition! Love anything done by this amazing woman.
Came across this presentation by accident, never heard of prof. Roberts before. Very inspiring, the book is definitely on my wishlist! Fascinating field of enquiry. As a public figure, she reminds one of Victoria Coren Mitchell 🙂
The acoustics in this room are lovely...
I love your work on comparative anthropology! I would like to ask if there are any differences among the 2 editions of the book you held a topic on here? i know they are cheap but its been a bit of rough seas as a student of biology.
I always thought Alice was pretty perfect.
Very likeable person, Professor Alice. Sure like her documentaries.
The recurrent laryngeal nerve (RLN) solves a complex software timing problem for the brain by implementing a simple hardware solution. Namely, ensuring in the most flawlessly parsimonious way, that the larynx is in speech position before the action for speech arrives( encoded in the RLN ). So please don't reroute it. However, please fix the inverted retinal problem in our eyes, boy do I envy molluscs that got this right.
I got into biology in a very shallow way. But I'm over it now and just like listening to you talking in layman's terms. I love learning about anything now, as long as it's spoken with passion, and you are one of the best. Good health to you and your family.
Why have 36 people disliked this video?
Could it be they are creationists and don't accept reality.
It is you who doesn't accept reality. This is simply fraud.
who else!! aka martin ploughboy
@@martinploughboy988. It cannot be fraud if it is supported by verifiable evidence from multiple sources. Where's yours?
@Steven White IF it exists, THEN it is an asinine designer. and why assume it to be a he?👀
@Steven White creationists argue that the creator (God) must be an all intelligent, all knowing being. when evolutionists say that so many of the aspects of our bodies are flawed or illogical we mean to use that as evidence that there was no intelligent thought put into it. rather, it simply happened that the body developed that way because that is what allowed someone to survive
Great insights into such a complicated process 🤔
I'm Spanish, and even though I studied Languages& Literature, I'm interested in Science, Biology, Anatomy...I love this Doctor, I love the way she speaks, I love her standard, polished English. I can understand her fully, both the way of speaking and the topic
I've got the Spanish version of the visual guide of the human body, and it's fascinating. And soon I will be receiving her book, shown here on this video, about the evolution of us
Great, great, great, dr. Alice Roberts
I wish I had such an amazing lecturer ❤️❤️❤️🤍🤍🤍
Professor
ALICE WAS BORN IN BRISSEL ERE, BRISTOL.
Hadn't ever thought of it quite that way before. It reminds me of Microsoft's operating systems, glitches and workarounds.
Hi Dr Alice, You are simply fascinating. The way you explain Science is mind blowing. I always thought that You are the Carl Sagan of the Human Origins !
Best Wishes to You.
🌿🍀🌷🌹🌹🙏
If i had teachers as interesting as Alice i might have liked school and learnt something!
is that the only reason?
@@MrDaiseymay Good question.
For example, a teacher cannot make a student do their homework - only the student can do that. If a student doesn't want to study in order to master the concepts being taught, then they won't study and they won't learn.
Recently purchased your Kindle book, excellent analysis and descriptions. Multicellular life has come a long way in 500 million years, 🦠 to 🐋 🤗
A good explanation. I always wondered why knees were not more robust.

can someone link me to the tweet or thread on desired human body changes at 8:05?
Yes wonderful point, I have often thought too many scientists have no idea of what other scientists do. It's time to get some synergy going and find a way to link these types of research. Then progress will really take off.
Aw,I love you Alice!
what a beautiful and smart lass Alice is :)
Omg, this dress is mindwarping.
Wonderful content
Thanks for sharing and hello from Texas
Thanks for watching!
Alice is so easy to listen to.
There has been a tv series called ‘Your inner... ‘ (fish, reptile and monkey) where also the nerve was mentioned. I hope you do a program about the book ‘The incredible unlikeliness of being’ and can’t wait for the series you mentioned.
Big fan of yours Alice, read all your books and came to see you at Birmingham town hall a couple of years ago, on the Tamed tour.
I was wondering what your views on gender differences are and what you think of the idea that gender is socially constructed.
What a charming young Lady she is, I love her programs and try to watch all of them, they are so informative. For a subject to study in relation to evolution, it would be good to investigate if the body could use the food and water we consume more efficiently so we don`t need as much.... that would change the world in a big way :-)
There is. It's called fasting. Or simply cutting back. On the evolutionary
scale, our bodies are still in the hunter gather mode. What this means is
there are not 3 meals a day for them or us. `There were times long ago when
food was scarce and people had to go long periods without food. There is an
old Egyptian saying. " 1/3 of the food you eat is for your health. The other 2/3 is for
your Doctor.
What a wonderful clip! It makes me so… sad…feeling such a longing to know Professor Roberts… yet knowing that I never will.
The recurrent laryngeal nerve in the giraffe is a thing of wonder.
A PDF of the 1991 illustrated book, From the Beginning - The Story of Human Evolution can be downloaded here: www.davidpetersstudio.com/books.htm It is updated and expanded to include more fish, reptiles, etc. here: www.reptileevolution.com
You can question what perfect is? When do you achieve that? Who or what decides that and in what environment? We keep on evolving, so its also not static…..
Science doesn't look for perfection in nature. Perfection in nature is really an abstract concept which religions and myths originated.
@@indricotherium4802 why in your opinion religion originated perfection in Nature?
im interested in what she thought of changes in her own body when going threw her two pregnancies.
Prof Roberts: If you're exploring our fascination with and dependence on archetypes, it would be interesting to relate our use of them to the functioning of our brains, that is, the neural modelling of the world around us as a way of navigating and coping with the world. There's an obvious evolutionary angle insofar as this ability to model the world in complex ways is a key reason for our success as a species.
WEll said.
I would like to ask Alice if we are still physically and emotionally evolving? For instance, she mentioned our weak lumber area and subsequent problems that have occurred because we started to walk upright while our spine had only developed for being on all fours most of the time. And are we developing into a more intelligent species or are we just standing on the shoulders of giants?
Steve Norman
I was interested in the idea of are we still evolving as well. During one of the conversations with Richard Dawkins the evolutionary biologist, that I watched, somebody asked him that exact question. His answer was “who in our society are having the most children?”
The audience nervously laughed knowing that was not the intellectuals that are having lots of children.
I'm sure we are still evolving in many random ways. The problem is, that evolution occurs over millions and billions of years. Don't hold your breath waiting to see some changes. The real question is whether human beings will still be present on the Earth long enough for further evolution to occur.
Be interesting for her and a certain astronomy professor to make a programme about astro biology and alien evolution.
Brilliant woman.
I find the ideal of perfection to be imperfect. A perfect cube with perfect sides and edges is boring, add some imperfections and it gets interesting. That ideal is true for all living creatures that use sight, sound, and smell for picking a mate. We focus on an imperfection that we see as attractive, a mole on one side of the face in the right spot and is the right size, the size and shape of the lips might be smaller or larger than perfect, one eye might not be the same size and shape of the other but subtly different, might smell a distinctive way, might have a voice that's not perfect but just sounds perfect to your ears... It is the imperfections as well as perfections that attract mates together.
JETWTF, if you ever attend a Japanese Tea ceremony, you'll note that the cup in which the ceremonial tea is served is not perfect. That's deliberate, as Japanese ceramic artists will introduce imperfections to otherwise perfect cups. Their reasoning is that nothing human can be perfect, and anything that appears perfect hides the imperfection within. Better that it be seen.
I think most of us, all miss the severe complications that have to occur in order to be able to do, simple, taken for granted tasks, like digestion. The process of breaking down food, extracting the nutrients, getting rid of the waste. food for thought is that the gut designed or created has to know what food substances it has to deal with in the first place and cannot take time to tweek the design, or we would starve. As we know that in order to survive we have to ingest a certain number of calories and process their nutrients. It has to work from the get go. Further as the brain controls most of the operations of the body, I refer to it as the control centre, it has to be at a certain stage of creation, from day one or the bodily functions would not operate. we are all aware how complex the brain is, that a simple stroke can paralise the whole body in an instant.
Yes, and absorption of nutrients had 3.2 Billion years of evolution to start before complex life even began. The Human gut didn't start out as 1% of a human gut, it has it's origins in the absorptive surfaces of simple multicellular organisms. The octopus' oeophagus runs through the middle of its brain, so evidently there are many ways to develop a digestive tract from a small multicellular, innervated, simple organism.
Come such a long way since time team
Not forgetting that for any society to be successful you need a wide range of body shapes and sizes, as well as mental capabilities and outlooks. You cannot have one type of mind and body otherwise perhaps there's a risk we would all want to do the same tasks/ jobs.
You know this how? Please demonstrate that a society with only one body shape and size (for adults) cannot be 'successful' according to a stated definition of success. Demonstrate a causal mechanism that ties success to diversity of body shape and size and mental capabilities and 'outlooks'. You're just speculating from a preconceived conclusion.
Wished I hadn’t lost it. Back in the 1970s, Scientific American put out a special edition, where the authors redesigned the human body, without the mistakes.
I have no complaints.......;)
Feedback is part of Engineering Design, another name for learning Evolution, or natural Intuition.
Hi Professor Alice Roberts....
just going on the intro title of this youtube vid....As an aethiest I think of our planet in a different way to the average god worshiper,all things bright and beautifull all creatures great and small etc etc....my take on things Prof Alice.....is TIME.....this alone will see our beautifull planet go full circle and become the natural paradise it was before our mechanisation ruined everything thereafter......man (you & me) is hard
wired to forge ahead to make things
easier and better for themselves.
We don't have that much time on our beautiful planet but humans biggest evolvement is our knowledge base through learning from our predecessors.Our brain power knows we need to dump our bone structure and go semi android but that kills the human esq being which is US......just a thought....X
Paul,you wrote, "man (you & me) is hard wired to forge ahead to make things easier and better for themselves." I respectfully disagree. We seem to have little "hard wiring" -- something that alludes to the original digital electronic computers that had circuits designed to perform only one function -- instead, we seem to have remarkably fluid brains capable of adapting to a variety of circumstances, like injuries.
What we do have that makes it easier to forge better futures are: a) knowledge about how the future happens; and b) brains that seek social connections. When we put these together, we get groups of people who share ideas about what a better future for them would be. These people can then pool their resources and work together to realize the futures they've envisioned. None of these require abandoning our natural bodies -- we need only abandon the notion that the future is beyond our control.
You went on to say, "Our brain ... knows we need to dump our bone structure and go semi android . . .", which I find suspect, to say the least. If we choose to become cyborgs, what might it be like? And how about those who either can't afford to be cyborgs or choose not to? Given the chance, I wouldn't -- I remember encountering The Microsoft Blue Screen of Death too often to be confident that my semi-android body won't respond properly to my thoughts (like "I need to get the heck out of this burning building before it collapses on me!") at a critical moment.
On the other hand, give me the opportunity to remodel my existing body so it's more efficient and less apt to break (I've had three surgeries to correct a hiatal hernia, for example), and I'd likely take it. Whether that remodeling is accomplished through conventional surgery, nanobots working from inside, or through genetic engineering matters little as long as there are few (preferably no) adverse side effects, short recovery time, low cost and easy access to all people, matters little to me -- especially if it's in for a penny and reducing a few pounds -- in the right places, of course!
Someone should make youtube and tik tok fitness influencers watch this. Then hopefully they'd shut the hell up and go and do something productive. Always got time to listen to Prof Roberts.
I've often wondered whether the widespread use of cesarean sections will have an evolutionary impact on female hip size and infant head size in Homo sapiens.
Do you think that humans might, one day, be incapable of giving birth without surgical intervention?
I think both of you might eventually be right. An intriguing proposition but evolution happens so slowly it may be overtaken by human intervention. Eg. We might find a better way to ease the process. Or we might just make ourselves extinct, which would also solve the problem.
It would have been interesting/handy if she had shown the 're-modelled' human being.

The pouch would be somewhere to put your hands to keep them warm in winter
But i fear it would end up like a hanbag :D
Whatever is not perfect of the body , the mind fixes that through entering a state of mind called being in love . For those everything is perfect .
If evolution has taken us to this point in time and how we look, then surely it also shows that some people are taller, wider, non uniform in colour, hair, eyes, depending on ancestry. So evolution will continue to diverse our make up.
We're no longer evolving in geographically isolated pockets, though. International travel has made us one gene pool again, so the diversification that happened because of geographical isolation is unlikely to continue.
That's because we've dispersed & developed in diverse environments. We ought to converge now we've negated that dispersal & adapted our environments. However,the core of evolution requires diversity to work
Steven Hawking in his "Theory of Everything" talks about the "imperfection" of the universe and it is because of this "imperfection" that our universe is able to support life. Perhaps the reason human bodies are "imperfect" is because they have to adapt to changes taking place in an "imperfect" universe?
Ummm huh? I must have missed that.

I’d like to know when people are born who are different, when does the tipping point occur when you have a percentage of the population “more evolved”. It’s quite easy to spot the evolutionary back pedal, when one sees for example webbed toes. But what are the leaps we are making forward? Will society adjust for those who are left behind.......until they become extinct in the general population and just crop up as the occasional back pedal.
here is a picture of the model. I'm not sold on the 'improvements. Marsupial is a good idea though, but she could be a bit more pouchy.. imgur.com/gallery/hMUquVC
How long till we evolve to sit comfortably in airline seats?

I went to five recycling centres yesterday and they only recycle rubbish, not one of them recycle old men. 🥴
My wife and I life model for artist and have applied to become medical models at a medical school.
I think that science (and science fiction) seek improvement and repair of defects in the human (and animal) bodies. Genetic engineering, bionics and cybernetics are some examples.
i knew about that fish nerve, giraffes have something similar
The larangial nerve... it connects the brain to the voice box by taking a detour around the heart and back up.
This is what you get with evolution and also machine learning. Once a useful pathway is found it's very expensive to roll back and check if there was an even better solution. Plus a process like evolution can't 'roll back' cos is just a blind process.
Hello, Alice Roberts. I have watched heaps podcast many of your history of Britain. Well worth watching. I'm Australia and in the construction industry and see history through construction.
We could apple AI to the human body or brain. Elon Musk has some good ideas for the changes to our is a body and evolution.
The perfect body requires the perfect environment. If the environment changes...the body must change...survival depends on it...evolution demands it.

Alice darling, could Pandemics, mass droughts, famines, ignorance , along with natural disaster's, etc play a part in it ?
What an elegant accent!. Where is it from?
England ?? 😂🤣😂
It's a West Country accent. She's from Bristol. There's a Wikipedia page about her (Alice Roberts).
It's a modern day, evolved, pirate accent. Back in the day, a lot of pirates hailed from the English West Country, namely places like Bristol, which is where Dr. Roberts is from.
If you listen carefully, there's a rounded quality to her "r" sounds, which is an echo of that stereotypical pirate accent, with its ripe "yaaar" sounds, that we all know and love so much.
@@Plons0Nard considering there are about a hundred and sixty different English accents I'm going to say that might not be quite as specific as he wanted.
So she's a modern day evolved Dread Pirate Roberts?
🤣
Difficulties of child birth are an after effect of superior intellect evolution. It's strange that human hips didn't evolve at a similar rate. Perhaps staying narrow to be able to run faster ? As far as human anatomy not being perfect, that may be so but it comes pretty darn close IMO. For example the modern ratio (average) of arm length to leg length is exactly where it needs to be in order to survive walking erect. Or our ability to see movement, color differences & depth of field are balanced perfectly for our physical make up. Walking upright w/a 9lb. baby inside puts an enormous strain on the lower spine imagine moving that weight out 7 inches to a pouch. Twins would require a wheel chair. Even minor changes to our species during primal development would lead to extinction. (w/the exception of the recurrent laryngeal nerves as you say.)
Having a pouch would also fix the need to carry a purse around, too.
Socasso Vegetus. I love the marsupial solution. I always wondered why God didn't include this in humans, a supposedly more highly developed species. The womb doesn't need to be so large or complex. There is no drastic dislocation and relocation of internal organs. No labour and birth pains because the embryo is the size of a jellybaby . 90%of infant development including suckling then takes place outside the body, inside the pouch which expands to a purse and then a handbag. When a baby 'roo is at near child development it can operate and feed outside on its own. but if danger threatens it can pop back in the pouch and the mother can make off to safety at speed. All very elegant and practical. Then I realised that God couldn't do any of those improvements because he doesn't exist.
So, does a chimp have an appendix or wisdom teeth? It wasn't fun having mine removed
Actually yes all of the great apes and many other mammals have an appendix. Also all of the great apes have 32 teeth.
Removing wisdom teeth just became common as the human jaw became smaller.
An appendix should be even more useful for them because they eat grass/plants so much
Where does she get the time and money to become a professor of half a dozen related subjects and a doctor of medicine as well?
The flaws and suboptimal design features in the human body are also explored in a great book by Prof. Nathan Lents called "Human Errors".
Stephen Bedford
I saw a short talk by him on here, probably during the book launch. Have you read it? What did you think of it?
As any dinosaur will tell you... Perfection only lasts as long as everything stays the same...one asteroid on your plate and perfection vanishes in a mushroom cloud.
Or pandemic virus, global climate change, nuclear war...
Yes! ....and every time that a creature, plant or organism on our planet goes extinct, the opportunity for evolution of that species ceases.
I had a leaky valve so I suppose that's the same thing. I never thought to ask why! Shame on me, and the doctor never bothered to say it either, did he know?
Perfection is a subjective judgment. And you have relative perfection and absolute perfection. And you have 'fit for purpose' perfection. My car lasted for a more than reasonable 18 years, is that not perfection of a sort? Maybe the body is perfect, it is maybe more a state of mind that says one thing or the other? My state of mind is different from hers.
I don't think Perfection is really subjective at all although it could be depending on how you define perfection. I would define perfection as being Flawless for its function. An automobile is not perfect because it's operation overtime wears out the automobile. If it were Flawless - it should be immune to such a thing.
The human body by comparison has numerous natural aspects that are not Well Suited to how humans live. Our backs for example are very fragile for the type of Leverage walking upright applies to them.
The laryngeal nerve is quite inefficient since dips into our chest before going back to our brain.
Of course I suppose one could say that all things are subjective depending upon the defined context. If we define perfection as Flawless for its necessary operation - nothing is perfect. If we define it as good enough and makes me happy - well nearly anything could be perfect.
The word we use for anything that is not perfect is imperfect. We wouldn't bring up the word perfect for something that falls well short of perfection. We might in the case of something that we consider almost perfect, though you then have to ask how you know it's almost perfect and if you do, why do you live with the almost perfect when you can identify what is needed to bring it to perfection.
@@jarodstrain8905 - the spine is flawless/perfect for the job it was designed for. It's when the user overloads /abuses the spec tolerances that problems will occur.
The spine design that this Prof. Alice is asking for will be totally unstable & unusable because she is only thinking about improving 1 thing without realising the catastrophic consequences her change will make to the whole design specifications.
Evolution is never ending
Before listening to the video, I'm going to go out on a limb and say because evolution is always an issue of adapting which means it's building on what's already there.
Perfecting the body would mean that there had to be an engineered designed plan - and evolution is a process that doesn't have a plan.
Isn't adapting to survive changes in the environment a pretty good plan? No, evolution doesn't have a predetermined goal. it would be a pretty dopey plan if it did, as 'changing environments' is what our planet is good at. Any predetermined goal, or fixed creation would soon become extinct (in the planetary timescale).
@@splitpitch A predetermined plan a little like the anti vaxxers in a world with a century of global pandemics ahead...? Mother nature....she's such a bitch...and there's no arguing with her either!
@@splitpitch Now your just being logical.
I have a question, if an asteroid killed all the dinosaurs how come mammals escaped that catastrophe why didn't even a single dinosaur species escaped to continue the existence of their species ? This might be a silly question perhaps.. but I really would like an answer
:-) Birds and reptiles
Hey Bruh, it's because Mammals were tiny AF and the mammals that were around and survived were rodent critters probably hiding in the ground gopher style, weasel style, etc
It is an interesting question. We already know that mammals were quite small and diverse enough to survive post-apocalyptic event.
We do however, also know that majority of dinosaurs were very small also, so it would make sense for some of them to survive.
I understand that birds are descendants of dinosaurs, but they existed at the same time as their ancestors.
Its really quite surprising how many creatures have been around even before "Dinosaurs" that lived through that 65mil year ago thing...
Warm blood?
Well Keep on evolving
God made man and made all things not evolution
@@paulfellowes878 Yes Paul. Gen 1::27, “So God created man in his own image, in the image of God created he him; male and female created he them.” For these people to think that they could design the human body better is just arrogance. Rom 1:22, “Professing themselves to be wise, they became fools” keep standing brother!
I would have eliminated the sinuses as well. I think we only use them to catch colds these days.
Google 'what does a sinus do?' I think I'll keep mine!
@@mickleblade Because of the way our faces evolved, the maxillary sinuses drain from the top, so are more prone to clogging up and getting infected. So this is another 'design' flaw, which supports evolution not intelligent design.
Alice, think of the woman's birth cannal as a birth right, way of passage. What l mean is think about the life and transition of a caterpillar, into a butterfly, and if you tamper with the cacoon of a butterfly as it is hatching the butterfly will only last a few hours before it dies, is like most living things needs that struggle of life begginings, a right of passage. Another would be the hatchling of a bird, and so is the woman's birth cannal, as apposed to sesarian section. It breaks the bonding mechanism mother to child.
You do realise that human child birth is prone to complication precisely because of our evolutionary history of having to walk upright and run in a just a couple million years. The selection pressures of nature ordained that a high peri-partum mortality was a price worth paying for narrower, stable, upright pelvises.
Just because canal birth is natural, does not mean it's automatically good. Malaria is natural. The reason we have modern medicine is to subvert nature, and all the better for it.
every stage in evolution is an add on to every stage that was taken before, it is like time it cannot go backwards and start from a more strategic position, so going forward new stages are restricted to fit the frame work in hand. In more basic terms a horse could never evolve, even over an infinite amount of time into any other animal. In regards to perfection that is difficult to even imagine but what I would say is that we have tampered in the Evolution process of ourselves by using un natural interventions, and especially by medications and Toxins. We are actually in a stage of De Evolution where we are corrupting all that went before and all that lies before us and we are now acting like Gods with the power to re create but I fear we will rue these actions in time to come....
