Florida lizards evolve in just 15 years

Fearful of invading Cuban anoles or brown anoles, the native lizards reportedly began perching higher in trees, and, generation after generation, their feet evolved to become better at gripping the thinner, smoother branches found higher up. (Source: Nature World News)

 

A native lizard species from Florida has demonstrated some rapid evolution – in as little as 15 years – due to pressures from an invading lizard species hailing from Cuba, according to a recent study cited in Nature World News.

To put this in perspective, researchers say that if human height evolved as fast as these lizards, the average American man, standing 5 feet 9 inches tall, would soon shoot up to 6 feet 4 inches within 20 generations.
