The dandelions in my front lawn have you evolved. They used to grow on long stems, which I mow down. Now the dandelions produce flowers that sit right close to the ground, lower than the blades of my lawn mower. If I stop mowing for a period of time, they still grow close to the ground and do not extend long stems up.

But dandelions are beutiful and who wants a dull, flat, sterile looking lawn anyway? ;-) Oh well. 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.

[@nunyabiznez6381]

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.

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.

I had (and still have to a small degree) a population of cellar spiders in my home that evolved to be bigger and to move a lot slower (maybe to conserve energy).

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.

I think the speed of evolution is relative to the likelihood of the animal with the weak traits being killed off. Deers exist in huge numbers and only rarely do a few adventurous or young individuals have a run in with a car, so it's not a big enough factor to influence evolution. Deer also benefit from the fact that human drivers have evolved new driving habits to avoid hitting deer, so their cars won't get totalled. It's a two way street!

[@jamindavey]

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.

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.

[@christaaffe8251]

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.

[@maksymvoitovych4492]

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.

This happens to bears in arctic areas too. If you have a brown bear in a temperate area that starts to see a lot of snow, it will be highly visible and struggle to hunt, whereas it's white cousins would suddenly have an advantage. This works both ways, with white bears struggling to hunt in areas that see less snow than in the past and their rarer brown offspring having an immediate advantage.

[@HerrMisterTheo]

That's industrial melanism. They didn't "die off", the ratio between melanistic and non-melanistic moths changed. They're the same species. Now whether the overall number of moths was affected, I can't tell you. Btw, since the soot isn't a huge problem anymore, the white moths dominate again.

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.

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.

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.

[@KARAIsaku]

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.

They should’ve had a high and a low cut off for fish length so that fishing exerts divergent evolutionary pressure (i.e. two viable ecological niches, being “too small” or “too big”). As those two groups don’t have any actual mating barriers, they would intermingle to create more medium fish than can be fished. By only exerting evolutionary pressure to be smaller to increase fitness, we’re just making the fish smaller and smaller

[@williamweigt7632]

Water Under The Bridge Gillnets only allow a narrow size range of fish to be harvested. Smaller fish can get through the webbing; while much larger fish do not become entangled (“gilled”) easily. We use such nets to regulate our harvest of salmon and other fish, to keep the harvest sustainable, here in Alaska.

[@waterunderthebridge7950]

Nice to hear that there’s actual thought put behind some fishing operations :D Seems like a big chunk of the world probably hasn’t though, otherwise they wouldn’t have discussed that topic in the video

[@Sauvenil]

most places that offer sport fishing have "slot limits" where you're not allowed to take fish that don't fit the slot. (Basically, they're too big or too small.) And they don't screw around with the penalties - potentially hundreds of dollars per fish.

[@Chillerll]

@@waterunderthebridge7950 They don't necessarily do that to protect the fish though. It is expensive to transport, clean them, remove the guts, and package the fish. You don't want to do that with small fish which has not as much valuable meat on it.

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).

[@thelionoob]

where I live, a decade ago it was extremely common in the spring for sparrows to make nests on roof tiles. Now I haven't seen a nest like this in 3 years or so. What happens is, I live in a poor area and most houses have cheap roof tiles that don't insulate heat at all, but help during harsh winters and are hail-resistant enough. Its undulated shape makes easy nesting places for sparrows and they used to build nests there in the spring, but when summer arrived the tiles would get extremely hot and would cook the chicks until they jumped off too early and got eaten by dogs. That probably gave the sparrows that avoided roofs for nesting an advantage and now all of them make their nests in places like trees. Also, in a town 4 hours away from here the sparrows have way more contrasting patterns while the ones here have more grayish, muted colors. That town is way less urbanized than here, so my guess is: more humans = more cats = more predation = more need for camouflage rather than attracting mates Theres a lot of other physical and behavioral changes on birds here as the years pass, but I haven't quite figured out all of them yet.

Man those turn-headed sea snakes would make a great regional variant of Ekans. Ekans already has dark and light stripes normally, and it is a Poison type. So a solid black one that is Steel/Poison with the ability Shed Skin. I mean Game Freak already did the dead bleached coral ghost Cursola.

[@WebWingRecords]

I might add Cheetahs as an example of this at least in three behavioral sense. Cheetahs have been shown to be adapting into pack animals as opposed to solitary feline hunters in real time. I'm not sure of this is the same kind of hyper speed evolution you were talking about in this video but I think it is the coolest example.

octopus too - which has SERIOUS potential to lead to further evolution, since octopus are largely held back my solitary life, after their parents dying to give birth to them & so being unable to pass on any learned knowledge, each generation having a reset - until humans cause them to create "octopus cities" where they can learn from other octopus :)

[@jakeapplegate6642]

Lilac Lizard octopi are extremely vulnerable to brain damage because of their lack of a skull. Squid have a donut shaped brain that actually has its esophagus run through the middle and can give themselves brain damage if they try to swallow something too large. These are a couple of the reasons that hold them back from becoming more intellectually advanced.

[@lilaclizard4504]

@@jakeapplegate6642 octopus also have multiple networked brains, one in each tentacle & the ability to regrow tentacles & brains in them & we don't yet understand exactly what information is relayed between these brains & in what way, so even if they were prone to brain damage (which is highly questionable) that certainly doesn't indicate a likely obstruction to intellectual advancement, I mean humans have a tendency to get bruising or swelling in their brain that leads to brain damage due to the hard skull crushing the brain when it happens, along with a tendency to desire sports like football that are of high risk in causing thee concussions. octopus avoid all these issues with their lack of skull & also avoid limits on potential brain size

[@KARAIsaku]

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.

A great study done by Peter and Rosemary Grant was documented in the book "The Beak of the Finch" by Jonathan Weiner. The scientists followed the change of the finches beaks during a period of drought. The foods available to them were a selective pressure on beak size. People that don't believe evolution need to read more!
