walnut

Think about evolution, according to evolution we came to what we are now, from ape to yuppies.
And since evolution theory says that there is always evolution as long there is life,
then we are still developing, unless a big rock from space says no.
I imagine a toothless mouth, a straw-mouth, for sucking fluids, maybe two million years from now,
and a brain with the size of a walnut.
