Question:
I am doing a paper on the exploration of why two different types of venom evolved in snakes. I was wondering if anyone could point me in the direction I need to go? Or if anyone has a possible answer?


Replies:
I have found much information on different venom types but not about why they have evolved. Like most "why" questions in nature we can say "because it works," meaning that both types have been successful survival strategies for their species. I found one interesting old (1944) reference that discusses the evolution of venom (c. 18), but makes no suggestion as to why two different types evolved. It is: "Snakes Alive, and How They Live" by Clifford H. Pope.
