Fun Fact: Your teacher told you to watch this and your test is coming up soon.
mines in 30 minutes 🤪

@@boubacarbah2759 hope you did good :)
@@alex-ln2ut nope i failed :(
@@boubacarbah2759 aw it’s fine lmao bio is hard🥶🥶🥶 im have physics right now n have no idea what im doing 🤩
Watching this for biology class during quarantine
Same
same
Yessir
Yup
yeah me too
You are literally my teacher.
Seriously the most simplified and comprehensible explanation on cladograms I have so far discovered. I'm currently cramming for my Biology final the night before and throughout the entire course I struggled to completely understand cladograms and you've changed that for me in less than 10 minutes. Thank you so much!

CAUGHT
hi. an interesting question: according to evolution fly and mosquito split off about 250 my ago. fly
generation is about less than one month. so even if one generation mean
only 1 new mutation we will need only 10^8 month to change his entire
genome. or about less than 10^7 years. so fly and mosquito are suppose
to be different in about their entire genomes from each other. far from
reality.
The high rate of mutations you propose does not need to occur in to achieve the observed diversity, esp. in sexually reproducing organisms. There is strong pressure for stability for genes that penetrate to expression; due to the fact that its likely any particular genetic mutation that occurs in an offspring may be deleterious to an organisms survival, thus, causing most many mutations to never be passed down. For this reason, dramatic evolutionary changes in genomic groups tends to occur in "fits and spurts", in response to changes in the environment. The most dramatic changes to the environment, such as separation of once-unified land masses, meteor strikes, volcanic eruptions, will tend to result in correspondingly dramatic changes to genomic groups. That is: mutations suddenly have more potential than before. Or, in the case of a two groups of the same species becoming isolated from each other, certain types of mutations that would have been "diluted" out within a few generations of interbreeding (think red hair and black hair humans) may become the norm (certain areas of northern Europe have extremely high concentrations humans with having red hair.
as a 52 year old Army Retiree, that was extremity helpful. If I had teachers with tools like your way back in the 70's, I wouldn't be in school now.
Studying for my final now and I knew this would be the best place to come! Thank you so much!!!! Good luck to everyone else on their finals :)
I honestly don't know what I would do without any of your videos....Thank you so much! You have literally saved my grade.
I respect you so much. Thanks for putting up good videos.
I've been watching your videos for years and I couldn't thank you enough.
lmfaooo they look like

terry good eye I didn’t think that until I looked at this comment
Put that thing back where it came from or so help me!

@@domingopablo9613 The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. Ding A single lap should be completed each time you hear this sound. Ding Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start.

taking notes during quarantine. no finals this year WOOHOO wish it was my senior year rn
why senior year? I was a grad of 2020... and no graduation ceremony :(
I'm now in college which is all virtual.
@@abigailf.6212 awww I'm so sorry that's the only terrible thing about that and I hope they somehow pay u back for that it's a very special moment❤️
Kellen Willliams welp I was homeschooled, the program I was with wasn’t able to do it, so probably not :(
and once again Mr. Anderson saves us all
Hey man! Thanks a lot, helped so much towards me understanding this!
Have never commented on a TH-cam video before, but this was simply exceptional.
I have to make a parsimonious cladogram for my Comparative Vertebrate Anatomy class from different types of cereals and this really helped me understand how to make my own! Thank you so much!
Thank you! This is the only video that didn't put me to sleep.
0:30 “I’ve named them after myself, of course.” 😂😂
It is very helpful, and I am ready for the phylogenetic lessons coming soon. Thank you!
Wow! This really made sense. The textbook doesn't even come close! Thank you so much!
Thank you for explaining my college evolution class❣️💙
My bio teacher doesn't teach very well, but these videos REALLY help and make sense
this was great, you really helped me understand cladograms better!
Thank you! Your teaching is incredible! :)
Such an amazing explanation... thank you very much good sir!
Thank you! Very easy to understand.
Great video
Woah😊
This was actually really helpful
Also love the Cacodemon at 3:11
Thank you so much! I owe it to you. 👍👌
This was very helpful thank you
"aliens didn't come down and spill my milk" 😂 I'm dead 💀💀💀
please come back alive
thank you so much, it was so helpful
First thought it was a Beholder when I saw the thumbnail... Thanks for the great content!
Thanks sir very helpful for INJSO . Best resource out there...
Thank you!!!!! So helpful, I understand it now!!!!!
thank you so much mr. anderson!!!!
Thank you Mr Andersen! :)
Thanks m8! Biology state test in a few hours, really helped.
Your videos are excellent. I find them easy to understand and follow. Thank you
This really helped me for my test ☺
(aliens): 'Oh crap...he's on to us!!!'
This is so cool. This is why I bloody love science!
thank you sir you are the best !!!!!!!!!!!!!!!
What would I do without you!
Wow thanks mr A!!!
Very good!
thank you so much!
I'm watching this for class in class I don't appreciate being called out in the comments
WONDERFUL!!!
I actually thought Andersenii aquaticus was real before you said.
this guy is making a strait living out of this channel
Thanks so much!
nice explanation :)
So if appearances are similar does it mean genealogy will also be similar? If we assert common ancestor as is done here just by looking at the similarities are we not saying that genealogy is implicitly proven to be related without any evidence ?
thx Mr Anderson
Yay it is 2 am and I’m currently taking notes for my AP bio class Thursday ☺️
Update : oh would you look at that. I actually love this lesson &’ it was uploaded on my birthday
This comment was uploaded 5 years ago. Ive got an ap bio exam tomorrow and I’m curious to know how you did in the college board exam 😭
Thank you thank u thank u
My god that's Helpful
This is very good. I teach a course called "Human Nature and Human Values", which focuses on biological explanations for social and political behavior. I have to give the students a week or so of evolutionary biology and cladograms are one of the things I need to explain. This does my work for me.
March 2021 nanuet anyone?
what’s good bio classes
just have to say you are the best
tomorrows the ap bio test! i thank u for clearing up cladograms
How did that to?
1:33when that cladogram came outta nowhere bruh😂. How did he even know where to put them!
The power of editing
Thanks this is really interesting but what it wrong with your pond?
Your the best!
how would the closeness between lemurs and humans vs lemurs and tarsiars relate?
and how do you know...?
i need help on what common ancestors are
At around 4:19 letter H should IMHO branch out from the main trunk from between D and A as mouth is also present in F and E. Current red branch implies F and E does not have a mouth. Maybe I'm wrong though. Please enlighten me. Thanks.
+Adolf Szabo no
Is that jane goodall
I saw that too!! Was a fun little thing to add
The simple is anwer is usually correct
My cake was eaten and my dad said it was the cat.😓
Just a questionn... then how about the circle with the eye only... couldn't it also be that the mouth was lost? just like how the eye was lost?
Damn those aliens for spilling my milk!
thanks!!
Can cladograms represent punctuated equilibrium or is it always gradualism.
Great video! thanks :) so much more interesting than how my professor puts it lol
6:24 does that mean the lemurs and lorises are closely related to each other? Or the bonobos are closely related to humans
There's 7 minutes and 17 seconds I'll never get back
What's the difference between cladogram and a phylogeny though?
kittycat123e phylogeny is the study , cladogram is used in studying characteristics
OMG
THANK U. U SAVED MY ASSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
KID: THE ALIENS SPILLED MY MILK MOMMY
MOM: IT WAS THE CAT HONEY
KID: ALIENS..... IM SURE
What the crap does this have anything to o with his video????? STOP TRYING!!!!!!
I would have appreciated you as my Biology instructor in High School....I did well though I could have done better. Some how I learn faster the way you just explained this info.
Thanos snapped and my milk spilled.
So does a clade hypothesis that a blackbird and bat have a closely related black flying common ancestor?
birds and bats do have common ancestor.
but it was not that recent, their common ancestor was some sort of amniote like 300 million years ago, before they split into sauropsids and synapsids
they looked like small lizards that evolved from their amphibious ancestors.
but it was not flying. and i dont know which color it was.
AP test on monday, just watched all the videos in biology playlist
what program do you use to make your videos
how do you know if different related organisms are species or sub species?
so where all studets?
nice
please make a video as to how to make a strict consesus tree >~
This video eclipse my 1 hour lecture where lecturer sprouts nonsense
Paul Anderson is the G.O.A.T
Greatest Of All Time🙏🏻
So, I have to use 8 characteristics for each of 6 mystery creatures, upper and lowercase letters representing primitive and derived traits....none of the creatures have exactly the same lowercase letter (the primitive trait). How the heck do I start this?!

What if he had to choose between the cat or dog that spilled his milk
my bio test tmrw 🙏🙏
I say that H would actually be near D-A because putting it near A-F wouldn't make sense. However putting it near D-A would make sense because D shows the eye, and H shows the mouth. So it evolves into a eye-mouth-arrow-circle monster. hats why it should be near D-A. :)
=) thanks.
You know, I never thought of this before-- I could use a cladogram to build a character sheet in creative writing. Then I could sort my chapters according to which characteristics I wish to reveal. Not exactly the standard, but maybe I can expand the implications of the word "creative." :)
if you respond to this after 7 years you are a legend
POV: your biology teacher had you watch this.
I mean, this is better than doing actual classwork
