A century of anatomical and phylogenetic studies have determined that snakes evolved from lizards. 90 million years ago the snakes story begun. The first pre-snake recognized ancestor appeared 90 million years ago in Argentina. But one thing to say: We don’t know where she came from!
I’m really interested on evolution in snakes. How they evolve? Why? How? against what odds? against which species and with the help of whom? how genetics changed and what are their genes capable of?
By te way I made an Snake Identifier iOS app available here.
To have a solid foundations on evolution and biology is crucial for any conscious being that wants to become a scientist. Curiosity and imagination are powerful tools for succeeding in the never lasting journey.
