- So why is there such a variety of species in almost every type of
- biological environment, when they ultimately came from the same
- ancestors? The more similar they were, the more similar their needs.
- How did variation come about? Granted, all humans today are extremely
- close genetically. But how would you have explained the existence of
- the Neanderthals, who, by almost any evolutionary time scale, walked the
- earth only an instant ago? Or would you like to assume they were
- just as smart as us?
-
- As for nature requiring a sacrifice of certain abilities or organs, cave
- studies have clearly shown that, without need, abilities and organs can
- atrophy faster than they evolved (cave animals have no color and can't
- see). It seems plausible that something as supposedly genetically
- complex to maintain as intelligence might atrophy rather quickly without
- selection (I'm speaking of a time scale a bit longer than what would
- pertain to arguments about low academic achievers having more children
- in modern society, etc.).
