Though the lizards may seem like a portal to a bygone era, their habitat and survival faces serious threats today.

Matt McElroy hopes to answer how and why biological evolution occurred in the past, and what role thermal adaptation played in this process.

Studying hybrid zones offers a unique view into the evolutionary processes that either generate or extinguish species.
