Problem: Researchers in Puerto Rico found that in urban habitats, crested anole lizards have more scales on their toes and larger toepads that help them grip surfaces compared with anoles in the native forest habitat. The researchers estimated that this anole population had been exposed to urban environments for 30-40 years, which corresponds to 100 or more lizard generations. What hypothesis might explain this observation? Need Assignment Help?
This could not be an evolutionary change because evolution can't happen this rapidly.
Crested anoles are naturally tolerant to urban environments.
This anole population is evolving to better adapt to urban surfaces such as glass and concrete, which are more slippery than the surfaces in the native forest habitat.
This is an example of Lamarkian evolution.
