Nature's response to urban sprawl | DW Documentary

- It’s a new and surprising chapter in the theory of evolution. According to recent studies, it’s in our cities, of all places, that animals and plants adapt particularly quickly to changing living conditions.
Nature's response to the spread of cities is astonishing: Why do catfish in the river of a French city systematically prey on urban pigeons on the banks? Why do female birds on a university campus in California suddenly change their mating behavior? How do mice in New York's Central Park cope with an altered diet of human food waste? How have killifish in the Atlantic built up resistance to deadly chemical waste? And, is it possible for moths to adapt to nighttime light pollution?
New research provides surprising new insights into Darwin's theory of evolution. Nowhere else do animals and plants adapt so quickly to new living conditions as in cities. Biologists have long known that animals and plants occupy new habitats in the vicinity of humans. But now, new genetic analyses show that these adaptations are accompanied by significant changes in DNA.
Even more surprising: these evolutionary changes have not occurred over periods of millennia, but within just a few decades. The process has amazed scientists, who watch as nature transforms even our most hostile man-made interventions -- pollution, light pollution, noise, garbage and dense development -- into creative energy for new adaptations. Some researchers believe that our cities may soon develop their own, brand-new life forms.
What are the implications of these developments for the balance between humans and nature on our planet?

I had a recurring tought for the last few years while walking through few parks of Dublin, Ireland that all these swans and pigeons and other bird species must have a drastic raise of stomach cancer (or other cancers) from eating the highly processed bread-like product (i.e. toast 'bread') that many tourists throw at them. Good to see that there is actually a proper global research effort going on looking at impacts of our 'civilisation' on other living beings.
I would imagine that they are probably fine like how most people are fine eating bread. Pigeons don't live very long, it's unlikely they are going to develop a cancer from bread of all things.
Yeah, I agree with you.
I had a singing thought walking through Dublin that indigenous Irish population is at drastic risk of extinction due to invasive species who don’t belong there but who are being brought in by global elites with ulterior motives. Have you noticed that?
global research that you europeans have focus on money progress technology ommiting the most important aspect of our existence through proper healthy eco system your continent is doomed because the same thing happening to this animals is happening to your population look at the drought in europre because you destroyed ALL your old native forest by the time you get your result from your research your continent has already been destroyed into chaos war famine and viruses...
I mean look at a place like the netherland you europeans bragg and rejoice about the technology and planning allowing to reclaim all this wetland marshland swamps that are vital for errosion and floods because somehow in your small brain you think your science and tech is powerful enough agaisnt nature no it is not and this i why holland in a few decades wont exist it will be reclaim underwater by mother nature.
I noticed an example of this just last night. I live in a city on a river and we have a lot of geese in the area. I was at a very large discount store in an area with some retention ponds that attract the geese. It was a couple hours after sunset on a low-humidity night so the temperature was cooling rather fast. It was near closing time, so there was a lot of empty space in the parking lot, and I saw a large group of geese, about 30, walk into an empty area of the parking lot, and lay down. It seemed an odd place to take a rest, but I think they were enjoying the warmth of the asphalt, which had been absorbing sunshine all day.
I am a beekeeper in New Zealand and i found the white clover study interesting scientists here have developed new strains of white clover but unfortunately my bees struggle to get nectar from them because the flowers are too long for the bee's tongue to reach the bottom of the flower.Hopefully evolution allows them to catch up or i can breed bee's with a longer tongue.
What an odd thought... Never thought I'd see someone say they need to have bees with a longer tongue. ..Welp from America, Goodluck!
Get a good lens/ glass to study with
A breeder is as good as his eye
... and, all the best, to you, D.T. with that endeavour. The power we humans are developing, to exponentially rework and reshape the Earths' environment, is an unprecedented, awesomely immense responsibility, a collective responsibility that is always passed on to the future. I'd like to think and feel that we are capable of dodging a sixth cataclysmic Extention Level Event ...
Red clover is your answer ✌️
We plant that on a plot that has been heavily planted the year before, after it blossomed etc we mow it off and let the soil take everything from it. Our Buckfast bees love the flowers and it replenishes the soil as well
then they are suposed to be pollinated by butterflies or smth else... not bees need to change, humans need to change
The biomass of a city (excluding humans, pets and pigeons) is paltry, and cannot compare to that of a forest. These creatures are hanging on for dear life. DW is putting a bright face on a dire situation.
As said in the Bible, cities are not beneficial for the ecological order of things, including us.
Wildlife is hanging on for dear life everywhere at all times. We humans just forgot how that's like.
@@HeortirtheWoodwarden So loss of habitat caused by humans is just part of the order of things? By that logic, you could justify extreme levels of cruelty toward these creatures.
True. Sweet talks don't make the situation look good. We can't go blind. We are destroying nature.
Wonderful documentary, as usually expected from DW. Inspiring and encouraging research. Thank you.
And let's not forget humans are evolving rapidly in cities. Just compare how evolved democrats are to rural republicans!
... yay, THERE, Henry-!!!
It-Is, As-If, &, As-Such, that there, co-insidingly appears to be, a seemingly simultaneous mundaneity, and yet, a most Mysterious & Alchemical aspect to nature ...
I've ways been interested and intrigued by urban wildlife. Glad to see there are people who have the same interest and are actually intimately involved in the study of the same. 👏🏾👏🏾👏🏾
Have no fear about sprawl..NASA lied believe it or not...The Team I work with found the binary solar system in 2013..The 00Skyview Team..The Gov in 2003 using the Subaru telewcope..
The party is over for 90 percent of the Human Species no later than the end of 2024...Plug this into everything else going on....We have over 1 million photos since it arrived in our inner solar systen since 2017 alone...And just so happens to be the Dragon of vRevelation 12..I write accademically..
Agreed 100%!
@@danielrobledo3132 Is my reply above your?
And hopefully they can improve the urban natural ecosystems
I'm only a minute in so I dunno if it's mentioned, but urban coyotes in the States have an interesting adaption story. I think there's a documentary about it somewhere - or I'm mixing that up with the Coywolf documentary.
The best and most well covered documentaries out there. Good job DW
All the time.
Another amazing, and interesting documentary as expected from DW. Thank you.
Excellent documentary, thank you for sharing it with us. I would be interested to see more on this subject.🖤🇨🇦
Brilliant doc as always. Instead of we adapting to the nature, we are forcing the nature to adapt to our lifestyle.
thats a bad morale to have :D
... and, may the "force"ing be with you, too, Sachin-!!! ...
This documentary is really top-notch! 👍
Great work. Insightful and informative!
I think it may be beneficial for those watching this to research the difference between evolution and adaptation. It seems that they use these interchangeably.
Absolutely. There are no new species being created in the examples given here.
Adaption is not evolution yet it's incorrectly called so.
Quite an interesting documentary, this one is. I clicked Like for this, plus added it to four of my playlists. After all, we should all be interested by this kind of information.
Absolutely love this program. Thanks for putting it on.
Amazing .... So intriguing to know that evolutionary processes have accelerated but not pretty sure if this acceleration will be good or bad eventually. Overall, it was very informative. Gives me the inspiration to study different species around my house.
And A.I. will accelerate the process even quicker.
Excellent content, as usual 🤩
Amazing documentary! Thank you 🙏
No one's talking about how fantastic the musical score for this is
We created this need, and every creature on Earth recognizes that change is necessary - except us.
Just an awesome video from DW. Every government should focus on species to maintain ecological balance. Thank you.
Thanks DW....as always.. amazing documentary....
Thank you for your support!
DW is the gold standard of documentaries. Always cerebral.
Brilliant presentation
In the third grade I remember I had a teacher that was teaching us about adaptations and I said to the teacher aren't adaptations just evolution? The teacher denied evolution was ever a thing a refused to talk about it. There's a reason I still remember that lol
Nature evolves and survives. Nature in all forms is a powerful force we should all respect.
God is the powerful force that created nature.
Amazing... very insightful. A topic of my interest
A beautiful documentary ❤
This could be a series! There are probably as many examples of this phenomenon as there are cities. I personally have seen raccoons that seem far more clever than their "country" cousins!💚🌲👍🤙✌️
Squirrels and rats, too! I've read that's because of the extra protein they get from trash cans and such, but I think it's also because the ones that aren't smart enough to avoid getting run over or trapped don't reproduce much.
4:31 Toronto!
First the SkyDome, then Southbound on Spadina Avenue at Ft. York Boulevard
Very interesting, very informative, very well done. Thank you.
Wow DW! Another brilliant documentary. The world is wiser. Go raibh maith agaibh
Those are some beautiful catfish at the beginning!
Thanks for posting
Thank you for watching!
Maybe they need to reduce lighting in some areas while moths are laying eggs. Likely they are food for some species that will suffer. Seems I have read something like a city accompdating needs of wild life to function and survive.
Needed to fall asleep to something. Perfect 👍
Great video!
Superb. Documentary. Like always , I can tell you about one more amazing example here in berlin, our city fox who are well adopted to city life and roam freely
... and the cityfied rabbits ...
Loved it!
Fascinating.
I purposely let milkweed grow in my front garden. And now they're all over my front yard! But that's okay if I can help the monarch butterfly species. And in the fall, the pods open up and make this soft silky material that birds use the following spring. Only then do I remove them. Some other creature lays eggs on the milkweed, it's kinda gross, they're EVERYWHERE!! They lay their eggs on top of the leaves.
Catfish is an invasive species. They grow fast and hunts very well as we can see in this documentary. In Asia, catfish released into rivers and lakes by ‘ prolifers’ has caused the reduction of other indigenous species.
One must put the native animals above all others, no releasing pets into the wild, trapping and humanely euthanizing invasive species (yes even feral cats), etc.
@@user-zy4wv7yx1z So many dead song birds yes .
if cities are altering evolutionary changes in the animals and insects what changes occur in humans?
Class!👍👍👍
How does changes in our gut bacteria cause changes in our bDNA in response to environmental changes. On such a level that it becomes inherited. I would love to know that answer.
Very interesting, there is more we do not know, then we know. And it will be always like that, thanks
The catfish hunting the pigeons was definitely a new experience I was not expecting that it reminded me of crocodiles hunting zebras in Africa
Ive heard of large catfish hunting and eating humans before
I've heard of large humans hunting and eating catfish before.
@@glenncordova4027 humans hunt on anything. See how they hunt for money in this capitalism.
Nature conservation is important
Hey @DW, The subtitles are mispositioned. They're stuck in the middle of the screen. This has happened to more recent videos.
Hi @Perhaps Yes, thanks a lot for pointing out this problem and drawing our attention to it. We're looking into the technical issue and hope to resolve it for all recent titles as soon as possible. Thanks for your feedback and apologies for any issues caused.
So fascinating but sort of causes me to pause, like what could come.
I'm a chick forest technician from Montreal! Wilding up my lawn was nothing short of death threats from the dated!
"You must keep your grass perfectly green and cut to this exact height! Flower beds must match your neighbor's, or else!"
35:19 classic statistical pitfall. Forcing a pattern when there's none.
It's almost evenly distributed, how did they come up with a linear regression
Given enough time, nature is infinitely malleable and resilient.
amazing!
Interesting research, send the bill to the polluters !
Now people can make pigeon fishing lure to catch these fish. You don't need to cast far anymore.
Used to see so many monarchs when I was a child. Now, I am surprised if I see just one during their migration period.
I remember trees covered in orange that looked like they were breathing as the monarchs moved their wings.
But there's little to no milkweed growing on the edges of fields and in the windbreaks.
Glyphosate and BT corn have broken their only breeding ground.
So we see less as biodiverse habitat disappears.
28:09 Scorton Creek in Sandwich Massachusetts??
Awesome nature
Those two words next to each other like that in this context are redundant.
Nature: awesome
Awesome: nature.
Same thing.
great documentary, but please remove the annoying audio..
Interesting
Of the three video clips "in the Dutch capital of Amsterdam" at 4:33 to 4:47, only the third can be Amsterdam. The first is certainly Toronto, Canada, and the second is probably New York, N.Y.
Killifish that far north, I didnt think they where able to live that far up.
That *fan service* at 7:58 hahahahaa
Plant fields of milkweed. I recall them as a child. They grew along rail tracks we lived by next to the city zoo. They are not weeds. please people do not pull them drom your garden or fields. Wish I had some here. Saw one along the road near unbuilt property. Now it is being deveoloped and it is gone. It has pricklies but is needed.
Unplanned experience of all time, right👍
I learned about caterpillars 🐛 transforming into butterflies 🦋 in kindergarten back in 1988. 😀
Good video but having background music throughout was annoying.
Although the evolutionary study results will be fascinating.
Documentary gets in a way for me to watch my ads.
I don't know what species of catfish we have here, but I saw one swallow dead animals like chicken, even the spongy layer of discarded diapers.
I often tell this to people who buy catfish.
Seattle has a huge population of rats along Elliot Bay by the grainery that fills ship hulls withgrain, etc. They beg visitors to the park for hot dogs. You have to clap to get them off the sidewalk to go to the bathrooms. They were looking at providing bird predators to thin them out. They need to reduce the spillage of grain from the silos.
Interesting documentary, but guys....
There is a voice-over of a scientist stating that there is evidence, while the material on screen shows there is no evidence?
The scatterplot shown at @35:16 with the corresponding r^2 of 0,19 (which basically tells you there is no relationship).
Also, what exactly are you showing? standard deviation distance (x axis) vs the average GMIS?
For a scientist, this is cringing...
It's not a proof, it's a narrative.
It shows that _perhaps_ there is more hydrogen (from hydrocarbons) in the city than in the country.
Agreed. Anyone with any sort of basic knowledge of data analysis should be able to look at that plot and see that there's no pattern. Pretty disappointing! I get that they're trying to build a story here, but lying about it doesn't help anyone.
certainly some coastal marine species will manifest adaptive behavior
around 25:30 Why weren't the White-feet mice released at the place they were caught ?
Trapped in a black box, taken to a place of mutilation and released in a foreign land, far away from the family borough. But then, that's the US way, look what they did to Black-feet Indians.
don't start at @9:58 you will get the wrong idea out of context
Yes the fish eats the invasive birds woho.
Anyone think we should be helping are ecosystems more even in the citys.
I've noticed raccoons, coyotes, deer, owls and even falcons living in suburban neighborhoods.
You can find all of them right in Manhattan.
we are in risk but the nature...
EXCELLANT WE HUMAN ALSO SURVIVE IN EXTREME CONDTION LIFE IS TO LIVE ADOPT AND SPEREAD EVERY LIVING BEING HAVE TO MAKE THE BEST FOR SURVIVAL THAT IS WHAT LIFE IS ALL ABOUT THANK YOU SIR
Catfish are long lived. How can evolution be involved. In the same small urban area I have watched two occurrences of a cat and a fox pairing up with each benefiting from foraging and hunting strategy. Kittens and foxlets are off the menu so it is a trait of tolerance inherited through nurture?
It's learned opportunistic behavior.
Coyote and badger team up to hunt prairie dogs and rabbits.
Why not cat and fox?
Can we propagate milk weed and scatter the seeds. I would plant them.
why can't I seem to move the captions?
Yeah they seem screwed, only on this video.
Yeah it's an issue for most recent DW videos.
Hi @Brovck, thank you for your comment and drawing our attention to this problem! We apologize for any issues caused and are looking into resolving the technical problem for all recent titles as soon as possible. Thanks for watching!
@@DWDocumentary really enjoy the content!! Thanks for looking into it DW Team!
I instantly heard that the man talking was a fellow Dutch by his accent 😭
So Heat Islands would be better suited for plants and animals from farther south of their range.
How do you manage to make all your videos exactly 42 minutes and 26 seconds?
Milkweed is disappearing due to Monsanto seed company and Round-Up.
Now, hydrogen being the most common element...like they say... No I know hydrogen isn't exactly water but these fairly basic fish seem to have evolved a workaround against a nasty chemical and live to swim into the future..
To me, that tells me that there's plenty of planets up there with living things in the water or waterlike equivalent, despite whatever odd toxicity may also be present in the biosphere of the wider universe... Cool stuff.
I don't know how I feel about this doc, of all the fine ones from DW. First, I live in Kathmandu, a population of millions that feel like kazillions. But the city sits in a valley (talk about a heat/pollution bubble) surrounded by pure paradise. I have no doubt the evolution of numerous species is going on right now inside the city, but the city is still connected to the countryside, and the wildlife reflects that. We even have plenty of monarchs, bees and frogs left still. So second, my point is not to give up on making cities more habitatal for ALL species, instead of letting them mutate to become impervious to our shit, like PCB. And finally, this doc FAILED to correlate these urban mutations to our own species and missed a chance to point out that, like the pigeon-devouring catfish, we too are evolving into a snappy species that has to find alternative food sources!
Catfish is good food. Very expensive here in USA.
How much?
I really wanted to see a pigeon drown... NOT! Thanks for that...
Adaptive ability and evolution are two different things
thanks for the NEW !!! documentaries' keep up the good work 99% of tv is wretched filth or a waste of time
I THINK THIS TYPE OF PROGRAM SHOULD BE ON TV INSTEAD OF SOAP OPERAS N GAME SHOWS N SITCOMS WHO ARE
NOT FUNNY ANY WAY AND IM USING ALL CAPITAL LETTERS BECAUSE IM PISSED OFF AT THE KIND OF PROGRAMING
THAT SURVIVES ON TV AND I WANT THE TV STATIONS TO KNOW IT
IF I COULD GIVE THIS PROGRAM 100.000 LIKES I WOULD
I get where you're coming from but TV stations don't care. Soap operas are very popular as are reality tv shows though goodness knows why. I rarely watch TV just some sports and documentaries and the odd film but as long as people watch what we would consider drivel that what will be broadcast. I'm very grateful for TH-cam and providers like DW.
Have we crossed the point of no return in terms of damaging the planet? There is no such point. We need to trust that our thought, which is our greatest quality, can change nature. We only need to understand the direction to which we should aim our thoughts. What should we think about? What condition or state should we aspire to and ask for?
In order to save our planet, we should think about positive human connections. That is, how can we, in our connections, keep nature safe? How can we all together protect our world? If we truly wish to better our planet, then we should see people holding a concern for how to positively connect everywhere that we look.
It has nothing to do with recycling or other activities that we commonly associate with as being sustainable. If we come closer to and consider each other, that we will reach an entirely organic, perfectly connected and round state, then the negative forces will disappear from the world.
We need to understand that if we start thinking better about each other, then the planet will recover from all harm, because our thoughts are the strongest force in nature. Likewise, our negative thoughts about each other are entirely to blame for damaging the planet. That is why the more we recycle and invest in energies and activities that we commonly think of as being sustainable, the worse our planet becomes. Nothing will work to benefit us until we reach a state where our attitude changes toward each other for the better to protect and improve our planet.
Hellalujeh DW!
This guy is crazy I’ve lived in Texas in New Mexico and Oklahoma. The wildlife is getting more prevalent bc their are less farmers and more people move to the city. Less people hunt than ever before so wildlife population is growing.
It depends what the countryside is used for. Here in Europe, there is very little actual wild areas anymore. Almost all the surface is used for some sort of crop or the other. Weat , vegetable or trees. I think the US has more space that is not intensively exploited.
Wonderful😁❤🌍🌈!!!
Hello how are you stuff in the between friends makes it take way too long. I'm motivated.
Excellent documentary, but there's no instance of any research from the global south--makes it seem like all science is always done by the north. I know that at least in urban ecology there's so much great work being done elsewhere. Filmmakers must ask themselves if they're being represenative.
Might be better to remove invasive species catfish, and add a new fish to thearket.
