  • So I set up a lizard racetrack, and I fitted the racetrack with different surfaces.
  • One was tree bark, one was metal, like fence post metal, and then one was painted concrete.
  • And then I took high speed video of these lizards racing up the racetrack.
  • You might be wondering why we're racing lizards.
  • I promise it's science and definitely not an underground lizard gambling ring.
  • There are more than four hundred species of anoles throughout the Caribbean, Central and South America and the Southeastern US.
  • That diversity has made them an unlikely hero in the science world because of their remarkable ability to adapt to different environments.
  • Biologists like me have studied them for decades and published literally thousands of papers on them.
  • But one thing we're still trying to answer is how these lizards are evolving to thrive in yet another major ecosystem, cities.
  • It turns out these scaly city slickers are adapting to urban life in some really surprising ways.
  • I'm Shane Campbell Stayton, and this is Human Footprint.
  • Juan Ponce de León founded the settlement that became San Juan, Puerto Rico in one of the oldest colonial cities in the Americas.
  • Five hundred years later, that tiny colony has grown into the third largest city in the Caribbean islands.
  • But amazingly, you can still see native wildlife here.
  • If you walk through the city, you'll just see them on everything.
  • Kristen Winchell is an expert in urban evolution.
  • She studies lizards called anoles, which live all over the American tropics.
  • For Kristen, anoles aren't just a scientific inspiration, they're also her artistic muse.
  • I guess, first of all, what is the greatest animal and why is it anole?
  • I don't know, they're just fantastic little critters.
  • They're so expressive and so charismatic.
  • And I mean, they're also great for scientific study.
  • If you can't tell, I'm a big anole fan too.
  • I used to catch them as a kid in South Carolina, and I've been studying them since grad school.
  • Kristen and I actually worked together on anole research here in Puerto Rico.
  • I feel like most people, they're like, okay, I want to study them like in forests and things like that.
  • You decided to go study them in the city.
  • It was because I was looking for a species that might be adapting to urban environments.
  • Came across anoles and started reading about their rich evolutionary history and rapid change after you modify the environment.
  • I just had this moment where I was like, if this is happening, it's in these guys.
  • Once you know what you're looking for, animal adaptations can be easy to spot.
  • You see, species that live in different habitats have different traits.
  • big toe pads that help them stick to leaves in the treetops, long legs that allow them to run fast on the ground, short legs that help them climb without falling on the tiniest twigs, and so on.
  • Kristen's question was, which of these traits, if any, would help the gnolls survive in the city?
  • All right, let's find some lizards.
  • Kristen and I studied the Puerto Rican crest of the anole.
  • Step one is to find out whether urban and forest anoles are different from one another.
  • Say it, and the lizard jaws will deliver.
  • Yeah, there's a female right there.
  • So we hit the streets to catch some lizards.
  • She's squirrely.
  • You're too slow, Kay.
  • Stop embarrassing yourself on TV.
  • I had one, and then I let... Yeah, OK.
  • Thanks, Shane.
  • Well, it's real nice.
  • Invite me on your show and then make fun of me.
  • Catching anoles is a delicate, scientific process involving a fishing pole and some string.
  • You go out in your hiking boots and your field clothes, you're going to get a lot of looks.
  • You can dress casual, like you're going out on for a little walk, even bring a little boom box with you.
  • That helps a lot because no one walks around doing sketchy stuff, listening to reggaeton.
  • Got him first.
  • Hey, bud.
  • We measure with a digital x ray all the bones in the body.
  • And you can see that they have these enlarged toe pads on the floor and the hind feet.
  • And so if you were to zoom way in on those, you'd be able to see these tiny scales.
  • And those let the lizards cling to the smooth surfaces.
  • So for the Puerto Rican crested anole, what did you find?
  • One of my initial findings was that in the city, the lizards had longer limbs relative to their body length, larger toe pads with more of these specialized scales on the toe pads.
  • Okay.
  • These are exactly the kinds of adaptations you might expect to see in cities based on what we already know about anoles living elsewhere.
  • They're clinging to things like glass and metal and even painted concrete, which is a lot smoother than anything you find in the forest.
  • And so there's kind of this combined selective pressure on toe pads, making them able to cling better and limb length, making them able to navigate the structural environment better.
  • The urban lizards were different, but the real test was whether they could actually outperform their forest dwelling counterparts when facing a uniquely urban challenge.
  • So I set up a lizard racetrack, and I fitted the racetrack with different surfaces.
  • One was tree bark, one was metal, like fence post metal, and then one was painted concrete.
  • And then I took high speed video of these lizards racing up the racetrack.
  • What I expected is that the urban lizards would be able to run faster on the concrete and the metal and the urban substrates.
  • Those are the environments that they were living in.
  • Yeah, exactly.
  • And so they'd be better at doing that than the forest lizards.
  • What I found, though, was that the urban lizards were just faster overall.
  • On anything?
  • On anything.
  • Even like bark and stuff that's in forests?
  • Even bark, no matter what angle, no matter what structure we put on the track surface, they were faster.
  • They're just hot rods?
  • Mm hmm.
  • In grad school, I studied how anoles in Texas, where the polar vortex causes rare but intense cold snaps, were adapting to the cold.
  • When I found out about Kristen's work in cities, I realized her urban anoles could be facing a different kind of extreme.
  • When I came down and tried out this big idea of our anoles adapting to cities, one of the things that I measured was body temperature and air temperature.
  • Cities create what scientists call urban heat islands, areas with much hotter temperatures than the surrounding landscape.
  • So a few years ago, Kristen and I decided to find out how urban and forest anoles responded to extreme heat.
  • Sure enough, urban anoles could take the heat better than forest anoles.
  • And we even found a few of the genes that affect heat tolerance.
  • These adaptations aren't unique to any one city.
  • We found the same differences between urban and forest Anoles again and again, all over Puerto Rico.
  • We can think of cities as the big Petri dishes that are replicated on a much larger scale.
  • No two cities are exactly alike, but for Anoles, all cities have some things in common.
  • To survive on the streets, Crested Anoles evolved longer legs, bigger toe pads, and better heat tolerance than their forest relatives.
  • And it happened fast.
  • Some of our urban study locations have only been cities for thirty years.
  • That's evolution in overdrive, even in lizard time.
  • So is this a feel good story of animal adaptability?
  • I think it's a big mistake for us to think that all animals are going to be able to adapt their way out of this.
  • We still are going to lose a lot of species as urbanization progresses.
  • Only two of Puerto Rico's ten anole species are found in cities, and just one, the crested anole, is really thriving.
  • So yes, some species can adapt, but the ones that don't get squeezed out.
  • I mean, that's another reason why we should be studying the plants and animals that are doing well here so that we can maybe engineer cities to be a little more favorable to wildlife.
  • So typically, when we think of ecosystems, we think of things like forests or deserts.
  • Should we consider cities as ecosystems as well?
  • Yes, absolutely.
  • And we should consider them as distinct ecosystems, just like we do all those others.
  • Some folks aren't as comfortable as Kristen is with calling cities ecosystems.
  • But the more I learn about urban biology, the harder I find it to think of them as anything else.
  • Cities aren't going anywhere.
  • And life on Earth is going to have to figure out urban living or be left behind.
  • So I'm going to keep cheering for Team Urban Anole.
  • Thanks for watching.
