Hank Green, you left out rattle snakes with defective rattles. Before humans were killing rattle snakes with shotguns, the snakes with defective rattles were uncommon, but now that humans have shotguns to kill them, the silent snakes are more common. These silent rattle snakes do shake their tails, but without producing a telltale noise, and thus are causing more snakes bites....

If you do and don't have the patience to wait for the dandelions to leave on their own (they will eventually), the best remedy is usually to use some fertilizer. The dandelion's competitive edge over grass is that it has very deep roots and can draw nutrients that is out of the grass' reach. It usually doesn't take much improvement of the top soil before the grass gets the upper hand and forces the dandelion to move to pastures more ... umm I mean less ... green.

I have observed rapid evolution over the course of some 40 years. Two examples. A species of clam that lives near me in Florida in the mud used to be randomly bright pink, light pink or white. A parent could have all three in the hundreds every time they reproduce. So if you were out collecting their shells you would be likely to see all three colors in equal amounts. Shell crafters, people who make decorative objects from seashells often pick brightly colored shells to harvest as opposed to planer looking shells. Shell crafting has been going on since the sailor's valentine craze of the Victorian era but it has grown to a wider scale here in Florida so much so that some county's ban harvesting live shells altogether. So due to the popularity of brightly colored shells, the crafters would harvest only the pink ones leaving the white ones to survive to reproduce. In 1979, as I said, the color demographics were more or less even. Today, you will easily find the white ones but hardly ever will you find either of the pink shades. A similar thing happened with it's distant cousin, another clam but that one comes in a huge variety of colors ranging from all white to every color of the rainbow and often many colors at once. At least that was the case again 40 years ago but today, the demographics of that clam is roughly 80% white and 20% multi colored. And like the other species, any parent can reproduce any of the colors and in fact will have a thousand offspring at a time and every color of the rainbow will be represented in one mass of eggs but mostly today you see white ones. I predict that 2nd species of clam will be 96% White in 40 years and 99% white in 120 years and in a few more centuries, all color will be bred out of both species. There is also a species of sea snail that when first discovered was up to 18" long and quite heavy. The snail would simply keep reproducing throughout it's life and just get bigger and bigger. Due to harvesting preferences being for the largest display worthy specimens, you never see this species over a foot long any more. But also this species tended to reproduce only after it reached 10 inches in length. A malacologist once told me that they simply didn't reach sexual maturity until they were 10 inches long. Prior to that any offspring would be deformed or sickly. Recently I have observed specimens as small as six inches laying eggs and when I examined some under a microscope I found they were perfectly formed. I saw one in a museum once that was 22 1/2 inches long. It was accompanied by an egg case that was 2 1/2 inches thick. The egg cases I see today are half an inch thick. It's basically the same species but now I think we could call today's version a sub species, a sort of pigmy version of their ancestors. To my knowledge no specimen of that species over 14 inches long has been seen alive since the 1970's. All this said, they are actually a very common species. I could go out into the harbor near my house at low tide and there is a 75% chance I could fill a shopping bag with them in an hour. Smaller specimens have little commercial value but the foot long or nearly foot long specimens sell for about $50 in souvenir shops.

Re. the cliff swallows with shorter wings being more manouvreable; that's exactly the reason that later versions of the Supermarine Spitfire had their wings 'clipped' in WWII - i.e., the wings had the outer tips removed. The clipped wings increased their rate of roll, enabling them to go from straight and level flight into sharp turns significantly faster, and it also improved their speed at low altitudes.

The thing about sea microbes is interesting. About 10 years ago when I first started going to school for biology, I got into the DIY bio scene and was discussing possible avenues for research with one of my professors. I mentioned plastics in the ocean and the utility that a microbe that could eat them could have, and her response was, paraphrased "That probably isn't a productive avenue for research. Developing a novel trait like that isn't really something we can do very easily, but nature will probably deal with this particular problem on its own soon enough. Bacteria are always finding new metabolic pathways and I doubt they will take long to find a way to exploit this new carbon source that has suddenly shown up in such massive quantities." It's interesting to see her hypothesis panning out only a decade later.

I believe spiders are evolving in cities too. They generally avoid the light. But they learned to construct their webs near the lamps on the street or outside a house, because moths and other insects are attracted to the city's lights. Moths in highly polluted areas are also grey-colored.

Very interesting, thanks. However the Cliff Swallows story raises some questions for me.. longer wings will have higher metabolic costs to grow as well which would also make short wings a useful adaptation for survival. This isn't a contradiction to the idea that increased manouvreability might help cliff swallows escape from car accidents or catch insects better when they are in low availability but as with any evolutionary question there are a variety of factors that can be operating.

I wonder if birds in cities or other noisy places have evolved for their calls to be heard amidst the din of the city by other birds over longer distances. I remember sitting at a traffic light once in a noisy city and being able to hear a robin call very loud above all the other noise.

Obviously, this is just one person's observation and my subjective interpretation of it, but when I started driving here in the UK in the 1970s it was really common to hit a rabbit on the road. They'd just run out in front of you, particularly at night. Folklore stated that they were attracted by the headlights. Now, forty five years later, this very rarely happens; you often see rabbits on the verge, but they almost never run out any more. It has occurred to me that rabbits with a behavioural tendency to run out into traffic may have gradually died out (by being hit by cars), leaving survivors that don't have this tendency. Of course, this would require behaviours as well as physical attributes to be passed on genetically, but it's just a thought.

They became quite the spider hunters and I left them alone mostly because they do an excellent job keeping other spiders away. Since they began showing changes, I haven't seen any other web-making spiders in my home. Of course, these new cellar spiders seem to totally ignore pretty much anything but other spiders. They will eat their own without issue. I do think they might be on the verge of collapse because the past few years I have seen very very few of them compared to just five years ago.

Another rather famous example of this is the Peppered Moth also referred to as Darwin's moth. A Peppered Moth is typically white with small black and gray spots which help them camouflage against the pale bark of the trees they live on. Although there was a melanistic version, it was rather rare because it was more easily spotted by predators thus not surviving to pass on it's genes. During the industrial revolution the tree bark in cities was stained black from pollution. This caused the melanistic form of the moth to thrive in cities while the white form declined. That trend continued until the mid 20th century when clean air laws put an end to the pollution and within a few generations the melanistic moths began to decline and the white colored Pepper Moth returned.

Fascinating and well-done; kudos. And one more argument to add to our arsenal when dealing with the intellectually challenged; thank you. There is a finch (or similar) in England that would go south to Africa for the winter but many stuck around to take advantage of the many bird feeders, as the English are wont to do. Those birds quickly developed significantly shorter beaks. Happened within just a few decades in the period after WWII.

Hello ! In a city road in England the road was boarded with light coloured trees. Those trees were full of white butterflies. Then a factory opened its doors. The exhaust of this factory turned the trees dark brown. In the space of two years the butterflies turned dark brown. It is not a case of evolution but simply adaptation. Phil. Peace.

Another interesting rapid evolution example is the Australian cane toad. It was introduced as a natural predator for the cane beetle and has become one of the most destructive pest species in the country as has spread all the way from the East coast to Darwin in the North/West. This is a REALLY long way and involves travelling through a number of diverse environments. This has led to physical changed in the species. The cane toad populations that are found further West display features that would be beneficial in travelling the large distances required to reach a new habitat before it becomes saturated with members of their own species. They are significantly larger than the parent species and also have comparatively longer legs. Basically, this invading species has adapted traits that serve well for the vanguard simply reaching a new destination first and dominating the region before the smaller and shorter legged competitors arrive. Additionally, native species that live in areas which have become inhabited by cane toads have also evolved to accommodate their presence. The Australian Red-Bellied Black Snake has evolved a smaller head because those with large enough jaws to ingest a poisonous adult toad died very quickly after doing so. Also, several species of Australian bird have developed a preference for flipping toads onto their backs and eating the non-poisonous parts of the toad. While this was initially believe to be a learned behavior, birds that are raised in captivity and never see other birds doing this do now seem to instinctively go for the underside of toads when encountering them for the first time.

You forgot another very distinct evolutionary pathway for mosquitoes. Urban mosquitoes are very different from their “wild” counterpart (people who went into forests know what I’m talking about). Through selective breeding, we created a new species of mosquitoes. They are smaller, more agile and more careful. They come out only when it gets darker. once the light goes off, they try to remain still, preferably on a darker surface. Also, they come out to fly maximum 1-2 individuals at a time; Even though, there could be 10 more hiding in the shadows.

I'm very happy to see this video. The problem that troubled Darwin greatly was there seemed to be so few fossils of 'intermediate' species, those that showed gradual speciation. Darwin believed that evolution was slow and proceeded by gradual steps. Nowadays we know that just a few changes in genes are enough to bring about rather dramatic and abrupt change in the species, so that in just a few generations the old population would have been replaced by the new due to selection pressure. If conditions then remain static for a long time, these populations would remain static until again confronted with quickly changing selection pressure, whereupon the speciation change would take place within a short time. Hence the paucity of 'intermediate' species. Well done, keep it up!

Fascinating 😊thank you so much !

That part with the fish reminds me of something. People are encouraging fishermen to use nets with larger holes so small fishes can escape and breed. I assume that they assume that those small fishes they're targeting are supposed to be the young fishes, the plan was to make sure those young ones would still be breeding in order to make sure there will be always be more fish in the future. The flaw in this is that not only the younger fishes will escape the net but also small species of fish and fishes that are runt. Now, natural selection took place, we are getting even smaller fish. p.s. The idea of using fishing nets with large holes and its supposed benefits are introduced to us when we were kids. I even remember seeing it on tv.

also want to point out the radiation ata chernobyl has led to some interesting adaptations as well.

HANK, I have an excellent candidate for a follow up to this: the Hawaiian rock wallaby. This species evolved from a single, sibling pair of Aussie rock wallabies, who escaped captivity in the 1940s, due to a tropical storm. Since their original habitat was so severe, and their dietary needs so extreme, it was at first assumed they'd have died off quickly. Nope. This sibling pair had lots of babies, who mated with each other, etc., until they were discovered in the 1990s, with differences in size, colour, diet, and most importantly, genital arrangement and chromosome structure, making them unable to mate with the species they came from. Unlike feral pigs, which destroyed many natural habitats, these wallabies ended up fitting in, and even help disperse seeds of various of their new food sources via their feces. As for this video, I love it. I have often wondered if animals were evolving to adapt to cars existing, especially every spring, when animals end up dead all over our roads. I hate that it takes the slower, dumber ones dying to help their species evolve.

Great job on the video! I do want to point out a couple times you accidentally replaced the word adaptation with the word evolution, which can cause a lot of confusion. We see variations of subspecies that cannot breed with other variants as a result of rapid adaptation when forced quickly to adapt to new conditions all the time. When you use the word evolution, it implies an all together new species, not an adapted subspecies. Example of evolution being a mosquito that evolved into a new kind of beetle, rather than a mosquito that adapted to subspecies of mosquito. I’m simply pointing a common fallacy that creationists have a hay-day with, so please be careful. Still, great video, and keep up the good work.

I travel a lot by road here in Australia. Kangaroos seem to be particularly prone to road traffic. They are active generally from dusk to dawn and tend not to move away from approaching cars or trucks - they are likely to stare stupidly into the headlights until it's too late. I've often wondered if there is a measurable change in behaviour for kangaroo populations now compared to, say, the 1950's when road traffic started to really ramp up. With a kangaroo "generation" being around 6-8 years, that's about 10 generations since the 50's. You would think that evolution would favour more road wary individuals. My experience suggests not - there are still a LOT of kangaroos being naturally de-selected... But I'd be interested to learn if anyone has formally studied this.

Just to put this in perspective, last year when traveling on the Eyre Highway from Ceduna to Norseman (about 1200Km), I did an informal and highly unscientific count of carcasses along the way. Doing a count over 5Km or so at various spots and then averaging and extrapolating. My estimate was 10,000 carcasses over that 1200Km stretch of road. Australia has about 800,000Km of roads. If we take a stab at 25% of those being outback major roads, we're looking at about 2 Million carcasses at any one time. Which doesn't account for how many over any given period of time. Australia's kangaroo population is around the 50 Million mark. If anyone has better information, please feel free to correct this.

Note however that this is often referred to as "micro evolution" and relies on the presence of DNA information already present in a population. This DNA data then suppresses other variants, and if kept for long enough, will eliminate the other variants. As such this type of evolution is dependent on destruction of data.

There is something going around about urban Darwinism. How species in cities and around huge human communities adapt to their environment. Like example there was a plant that use to have no shells on it's seeds in an area. In a span of ten years they evolved to have hard shells and be prickly. Another example were catfish that were in a pond in the center of community (more like a small river.) Pigeons gathered at the edge of the banks. So over a span of a short time I think like ten or less years they've adapted to sneak up on them and snatch them like ninjas from the waters edge. And this expand of humans is causing species to evolve and adapt faster in order to survive.

As much as these are terrifying, they're quite interesting. I wonder how the animals on earth would look like in 50 years later.

“Let's be clear. The planet is not in jeopardy. We are in jeopardy. We haven't got the power to destroy the planet - or to save it. But we might have the power to save ourselves.” ― Michael Crichton, Jurassic Park “Life breaks free. Life expands to new territories. Painfully, perhaps even dangerously. But life finds a way.” ― Michael Crichton, Jurassic Park

I remember reading in my biology text in High School, back in the 70s, about a species of of moth in England that was various shades of gray; specimens collected at the beginning of the 1800s, when compared to specimens collected at the beginning of the 1900s, showed a noticeable difference - the earlier ones had a noticeably greater amount of lighter gray as compared to the latter ones, which were noticeably darker. The naturalists noticed that the moths, which spent significant time perching on tree-trunks, were harder to see on the trunks, as the tree-trunks were, in many areas, darker due to soot from large numbers of nearby furnaces. This made it harder for birds that preyed on them, to spot them. So the species had originally been a lighter gray, as that made it harder to spotted by the predacious birds, but selective pressure had previously mitigated against the darker ones, as standing out on the lighter (earlier) tree-barks.

The adaptation this video describes has a name, EPIGENETICS, an inbuilt system in all living organisms that governs gene expression. It is today known that even the changes in the beak size and form of the famous Galapagos Finches are not evolutionary changes in the traditional sense, but due to rapid epigenetic adaptation. These adaptive changes are also reversible. The video does refer to “adaptation” several times, but mixes it up with “evolution”, which is a completely different concept. Nor are the black and white mots and example of evolution, maybe not even of epigenetic changes, it is more probably, both variants existed already, the industrial sooth in England gave just the black ones an advantage. These days the white moths are back.

If the snakes can shed off the metal accumulation, we could research in breeding the high-melanin aquatic snakes that withstand high metal concentrations, then process the shed skin to have metal recovery or refining.

great idea. next step is figure out how to get bacteria to do that in a much shorter time

@@jjrusy7438 As far as I know this is already under investigation. First to bind unwanted elements, but I'm sure they think about harvesting some elements in the process too. Might be interesting for elements that are highly diluted and hard to get. But I would not put too high hopes in that.

Increased concentration for biology might be parts per million instead of parts per billion, so no it wouldn't be useful for processing.

jj rusy only problem there is the containment, it’s probably much harder to collect from large areas populated with those bacteria, so we’d have to keep it in controlled situations otherwise we just have bacteria collecting and then releasing all our good resources and letting the stuff hurt other creatures unnecessarily.

You are one of the best spokespeople for DARWIN and Sir. DAWKINS would have made you his personal ambassador. Love your content man and keep it up

There was a simar story with regard to crystalline structures in material science and the thought that infinite sums could have finite answers in mathematics. All of these sound vaguely like the rise of "ok Boomer" in response to those who are stubbornly hold onto outdated ideas. I guess scientists, mathematicians, and other experts are just as human as the rest of us.

I saw those lectures

Salmon, Herring and Cod are HEAVILY commercially fished compared to any "sport" fishing.

the main difference between natural selection and evolution is that natural selection is the differential survival and/or reproductive success among the individuals within a species whereas evolution is the change in the heritable characteristics of a population over successive generations.

I'm not sure if this counts as evolution but I sometimes have tree frogs sit and wait on our large porch window since my grandma's lamp is nearby and the bugs are attracted to it. At times a couple do this at the same time. However, this leads to potty issues because of them. During the day they stationed themselves behind the house tile ridges until night falls. And at times depending on the weather or time of day, Moths and sometimes other types of insects bathe(?) in the mornings all over our porch.

Ever heard the saying "exception from the rule"? And all changes shown in the video were gradual (even with the elephants) and minor compared to the complexity of the organisms involved; the only really interesting (and rarely directly observed by us) thing was the speciation of the mosquitoes - but they are still mosquitoes, so the overall change was minute (just the first step of speciation).

They probably exist a long time but in the 60s various bugs were found that enjoyed eating Jet fuel. Petroleum is a natural product and comes to the surface all by itself. Somehow, most of it is eventually consumed by bacteria like critters.

Great, now let bacteria eat nuclear waste, this would be useful :D

Longer wingspan=speed? Shorter wingspan=maneuverability? Before you clarified that I just assumed that longer wingspan was slower, and got sucked into vehicular turbulence easier, due to both the slower speed, and the increased surface area (higher area/mass ratio=increased reaction to turbulence).

It sounds to me like the first one about the cliff swallows is backwards. It make more sense that the shorter wings allowed them to eat (done daily) and car frogger (dogging) was a by product and something they became better at but didn't have do everyday. 🤔

All I’m thinking about is future rabbits evolving the ability to matrix out the way of my car.

Hank Green, I myself have noticed an example of extreme evolution right here in Charlotte, NC. Twenty-five years ago, I used to work in downtown Charlotte often, and there were roadkill squirrels absolutely everywhere. About two and a half decades later, this is not that case. The main thing that I've observed that is likely responsible for this change is their fleeing behavior. When I started to observe them, they would dart across the road to get away from one vehicle, then instantly double back on themselves and cross the road again. This was likely a way to confuse and outrun predators, but it does not work well with vehicles. Twenty-five years later, I've noticed both that they dart across the street a single time and keep going, and also that there is vastly less roadkill than before.

@mraggressivestoic8442

Or as the area built up and the human population increases, more structures are built on either side of the road, and above ground power lines now provide bridges so they can go tree to tree without crossing the squirrel speedway

Hank talks and i listen. That's just how it is. Regardless of the topic.

Also with African elephants, they are now only about 2/3 of the size that they used to be, compared to over a century ago. All the big ones got wiped out through hunting. The genes that produces the gigantic ones is pretty much eliminated. It's similar with the tuskless elephants. The tuskless gene may of only made up a small proportion of their population, but the ones with tusks nearly got wiped out in that region.
