Reply to comment by sennbat in Forest lizards have evolved genetically to live in cities — traits include longer limbs for sprinting across open areas, and larger toe pads with specialized scales for clinging to smooth surfaces like walls or glass by marketrent

Well, yes and no. There are certainly points of separation beyond which interbreeding either doesn't happen, extremely rarely happens, or results in a non-viable offspring.

This is one of the reasons I brought up the topic of ring species. They demonstrate an entire spectrum of interbreeding specimens, the ends of which either do not or cannot interbreed despite living in the same location.
