Ah, the dangers of taking an analogy too far...

In biology we usually talk about whether a species survives or not.  
The analogy fails because in browser security, having an exploitable 
hole in one browser is unacceptable.  The goal isn't to throw a range 
of genetic diversity against a potential extinction event and hope that 
a few individuals make it alive out the other side; the goal is to 
provide a secure browsing experience for *all* users.
