Planet dolan what animals have learned . to use the subway and obey traffic . signals what animals showed a rapid mass . evolution over the course of just 15 . years usually evolution takes millions . of years but here are ten ways creatures . are evolving right now before our very . eyes. i'm melissa and today i'll be your . narrator number 10 subway dogs the . subway system of a major city is . difficult enough to navigate for humans . like even if you're still looking at the . map and a dozen people have already told . you how to do it it's still confusing . but the stray dogs of moscow have . figured it out. they get on and off at specific stops . catch a nap on the ride and even hop off . and use the seats if there's room . they're also known to obey traffic laws . when above ground crossing at crosswalks . and only when the light turns number-9 . blind cave creatures for a creature to . evolve into not having eyes seems like . more of a de-evolution than anything . isn't losing your eyes moving in the . wrong direction well most of these . creatures can't really see much anyway . living in total complete darkness of a . deep cave and food is scarce as well so . energy is at a premium so since they . weren't using their eyes anyway they . just stopped developing them by doing . this they can serve 15 percent more . energy by not needing to use their brain . power and vision in fact several cave . dwellers are evolving to the point where . they are developing brains without any . vision centers at all number eight . tuskless elephants elephants originally . developed tusks to help them fight off . predators that was then now elephants . most deadly predator are humans and . tusks don't help them fight off human . predators they draw them poaching has . become such a serious problem that it . has actually changed the gene pool for . elephants previously around 2 to 6 . percent of african elephants were born . tuskless now it's closer to 98% as . elephants born with tests are frequently . poached for ivory in the past decade . about one-third of africa's elephants . have been killed for their tusks the . ones that are left get to live long. enough to breed and that always includes . the tuskless ones number 7 dachshund . resistant. you fish the indigenous zouk people of . mexico have had a ritual in which they . travel into a dark cell fear cave to ask . the gods for a good rainy season and . good harvests part of the ceremony . involves purring a hirable paste into . the water that is toxic to the cave fish . which incidentally are one of those . previously mentioned creatures that . evolved to lose their eyes the practice . was eventually banned by the mexican . government over ecological concerns but. ecologists have decided to study the . long-term effect of the ritual on the . fish and found that over time the fish . had evolved to become resistant to the . paste . number six poison immune mice some . european house mice particularly those . from germany and spain have evolved into . being poison resistant but it wasn't. something that happened through natural . selection over time . instead they inbred with an algerian . species of mouse that they had been . separated from for over a thousand years . this led to a rare gene transfer usually . seen only in plants or bacteria the . crossbred mice are resistant to poison . and not sterile like many cross bred . animals number five flowers with a bird . purge the rat's tail is a type of . flowering plant native to south africa . that relies primarily on birds for . pollination and because they rely on . birds for pollination they evolved in a . very specific way unlike most flowers . the rat's tail grows a flower at the . base and has a long branchless stem . growing above it birds perch on the stem . hang upside down and reach down into the . flower at the base of the plant to drink . its nectar scientists now believe that . this was an intentional evolution and . that the stem was grown specifically to . be a bird perch number four taani oil . color change tommie oils come in two . different colors a light grey and a . reddish brown the northern european . burt's generally have adopted those two . colors for camouflage the brown ones . blend in better with trees the gray ones . blend in with ice and snow as a result . gray owls are far more common in . northern europe especially finland where . it tends to snow more but over the past . 50 years there has been a steady . increase in the brown color tawny owls . as the climate warms and winters become . milder the brown coloration is more . advantageous and more owls of that color . are surviving and breeding number three . climbing lizards one of the most . stunning. examples of a species rapid evolution . has happened in the green anoles a small . lizard native to florida the brown anole . a closely related relative is an . invasive species native to cuba but they . are bigger and stronger than the green . annalee and quickly dominated the ground . as a result the green annalee has no . choice but to climb up and live in the . bushes and branches where their larger . cousins couldn't get to them this has . led to an incredible rate of evolution . in just 15 years the green annalee has . developed much larger toe pads with. stickier grips to better adapt to living . higher up in trees the rate of change . would be equal to the average human . height increasing from 5 feet 9 inches . to 6 feet 4 inches in a matter of 20 . generations number 2 chemical immunity . and fish the hudson river is not the . friendliest ecosystem for decades . general electric dumped over a million . pounds of toxic chemicals into the river . before environmental regulations came. into play in the 1970s and finally told . them to stop poisoning the river but the . chemicals known as pcbs are still there . resting on the river bottom and they're . very harmful to the atlantic tomcod one . of the rivers most plentiful native fish . the chemical exposure should have wiped . out the tomcod but instead it actually . mutated their dna to blunt the toxic. effects of the chemicals that's good for . the tomcod but bad for the larger fish . that feed on them not knowing that . they're about to chow down a toxic fish . number one bedbugs that won't die if you . see a bedbug the first thing you need to . do is kill the bedbug and then make sure . you kill its entire family that usually . involves sprays and bug bombs made to . poison the little pests death but in new . york city those tricks aren't working . anymore they're building up a resistance . to two common chemicals when used by . exterminators the other found in sprays. and insecticides commonly found in . stores the poison still kills them for . now it just takes an awful lot more than . it used to over time maybe it will even . make them stronger down . this video was made possible by our fans . over on patreon thanks for your support . guys thanks for watching catch you guys . next time .
