Not a single 'bit' has been disproved to date. This theory is in fact a body of facts, no wonder its taught as fact. Not only are we evolved from apes, we are in fact still apes.
Wikipedia:Most ape species are rare or endangered. The chief threat to most of the endangered species is loss of tropical rainforest habitat, though some populations are further imperiled by hunting for bushmeat.
How true, that humans are apes, and in my opinion, the most endangered.
