_"Snakes eat lots of kinds of animals and the best way to knock them out is 
going to require a whole range of toxins," he says.
_"By gaining access to the whole treasure chest of molecules you've got a 
much more diverse arsenal."_

 ...which flies in the face of what I've learned about evolution:  natural 
selection operates on the individual, not on the Class, Order, Family, or 
even the Genus........isn't stopping a heart just as effective whether 
feeding on mice or deer? (to give one example).

part of me suspects that the whole "testes" connection, is just parallel 
development...at best.............at worst, contaminated samples or sheer 
coincidence.

 after all, some of the "sources" mentioned in the article, include snake 
eyes.
