We tend to think of evolution as a slow, gradual process playing out over millions of years. But evolutionary biologist Shane Campbell-Staton says nature is now changing at breakneck speed to keep up with the world humanity has built. From tuskless elephants who escape poachers to wolves living in the radioactive Chernobyl Exclusion Zone, Campbell-Staton unpacks how life is rapidly adapting in surprising ways β and asks us to rethink how we can protect the planetβs biodiversity.

I like his shoe game
Geart always love to see Ted videos they are so informative π€
May the Anthroprocene epoch make the Permian-Triassic extinction event seem like a minor footnote in the pages of Earths history. Here's to making scenario SSP5-8.5 of the IPCC assessment a reality.
I love this. Thank you for your research on rapid evolution of adaptation.
Whether we are here or not the planet went through some several climactic changes and I guess that also would have spurred some type of evolutionary process whether good or bad
Love the part where he says " the simplest human whim…can fundamentally alter evolutionary fate" that is true of everything we do. Big or small every contribution to poisoning the earth and oceans with garbage and pollution…and even the tiniest measure of reuse and recycle HELPS evolution…not just for the most beautiful place in any universe…but awful humans too.

I think adaptation is the precursor of evolution.π
Amazing insights
My man chuck d π€£ if he got flavor flav in It would have been amazing. Good talk. Hope you're proud of yourself, bye.π€£π€£
Get yourself someone who backs you up the way random audience member #24 laughed at that Chuck D joke π₯π₯πππ₯π₯
Wow, the wolves and elephants presented here really show the change in heritable characteristics caused by humans. Once rare phenotypes like the ability to withstand high radiation exposures from exploded nuclear power plants or tuskless female elephants can become more common or eventually predominate their populations more often or exclusively and permanently, even while living in the wild. Their biological evolution is artificially caused, which is unnatural selection as opposed to natural selection, the process that Charles Darwin explained so well, and religion poo-poos. But the evidence here is clear. And if we can make such dramatic changes to wildlife and domesticated animals, imagine the changes we could be causing to human beings and our phenotypes even on relatively short timescales. Will we still be human beings or will we evolve into another species? Because looking into our past, the phenotypes of our ancestors made us unrecognizable as human beings using the definition we use today. They amounted to a different species altogether. We changed and could change again, sooner or later. It could be beneficial in a case like the wolves or more harmful like the elephants. If naturally, it's not up to us. Unnaturally, it is.
Reminds me of the misnomer-
"Save the Planet!"
Inspite of man's mismanagement, selfishness and greedy exploitation of earth's resources,
animal life will continue on.
The planet will go on.
Earth doesn't need saving.
Humans on the other hand…
It was an incredibly inspiring talk. Thank you. We are still writing this chapter, that's for sure. I believe it's only just begun.
Pushing a species into extinction is, in my vision, the worst possible crime. Worse than mass murder or genocide to our own species.
Your channel is such a positive force in the world, keep spreading the love.
For a second, I thought he was going to say that the wolves living in Chernobyl develop less cancer than their fellow wolves outside Chernobyl. That would be huge!
Darwin was aware of artificial selection.
Go vegan and save the animals and the planet
The non-sequitur reasoning of human egotism: Step 1 – demonstrate how many ways we are a horrible species, the absence of which everything else on this planet would benefit from; Step 2 – use that information to figure out how to further our survival? Maybe, if you're a fan of stories, you might want to notice that the story we've always told is a delusion of self-justifications and presumptions that somehow we can just completely change everything millions of years of evolution have programmed us to be. And that story is also a tale of horror for every other living thing in our wake. Probably not a great story to do anything with but end with a fade to black. You talk of cancers, but humanity has been the worst cancer this planet has faced. Any "good" we do for other creatures has always been moderately mitigating harms that wouldn't have existed for them in the first place if it weren't for us. And you're not a hero by "solving" a problem you yourself created. We can't just opt out of our essential, destructive nature with positive spins and TED talks. In philosophy the "trolley problem" demonstrates how we perceive morality essentially as a math problem: whatever ends benefits the highest numbers even if at the expense of the lesser numbers is the most preferable. Given that premise, with the millions of species that have died out as a consequence of the existence of humanity, the math suggests that the most moral thing humanity could do is be the next to go extinct, taking as few other species out with us as possible. Caring about this planet inevitably means rooting for a post-humanist future in which everything else can thrive.
This is something I've thought about. I'm glad to see it on a TED Talk.
Cool insight and glorious imagery
really shocked ,by the fact that we think really alike. well I hope we might work together in future,,currently I am just a student but soon I will be among greatest scientist that world will ever see

That comment "We live in a time when we are literally etching our decisions into the DNA of the species that live in, on and around us" was trully INSANE. I had never thought of it that way
Chuck D was OG
Do you know the first elefant killers is a billiard and piano players.
And then safari brits hunters.
Oh no its impossible π
