I’ve been learning some about rabies and learned about rabies causing hydrophobia. This is just a theory, I’m not saying I know anything about this topic to be knowledgeable, but if we could get someone with rabies to not fear water, could they survive?
Yeah its the prime example that evolution isn’t perfect just happy with good enough.
Also a great detriment to the “grand design”
It also illustrates a funny bit of the logic of multicellular non-clonal creatures: the germ line is the species. The other 99.9…% of you is just a fancy delivery mechanism, so it makes sense to add something seemingly super impractical to the anatomy if it slightly helps the sex cells.
