So I set up a lizard race track, and I fitted the race track 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 race track.
You might be wondering why we're racing lizards, and I promise it's science and definitely not an underground lizard-gambling ring.
There are more than 400 species of anoles throughout the Caribbean, Central and South America, and the southeastern U.S.
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-Staton, and this is Human Footprint.
