I still see retarded, autistic, and disabled people everywhere I go. If evolution was true then we would be rid of all dumb and disabled people millions of years ago.
You apparently know how evolution works like a kitten knows how a can-opener works. Evolution is not some [darn] magical wand you're making it out to be. Do "retarded, autistic, and disabled(we'll revisit this one)" die because they are just that? No. No they don't. Evolution is natural selection. Why don't these people die? Because we as a society keep them alive via charity, medicine and good old fashioned caring. There is no penalty for being such things, thus they are not filtered out through natural selection.
And "disabled" which encompasses all the above. It's not always genetic. Many things can go wrong in the womb (The mother smokes, drinks, or plays full contact sports against better judgment). Many things go wrong during child-birth. Many things go wrong period. The world is a dangerous place, boyo. And again as a society, we treat these people as just that--people.
"Defective" people breed. What, are you gonna stop 'em? good luck.
And evolution sometimes favors the bizarre, but it's a gambit; not all mutations are beneficial.
If your talking about that monkey skeleton Lucy, then it's just a fraud. They said the same thing back in 1908 about piltdown man. Piltdown man was supposed to be a very old monkey/human, in the development process. All they found was a skull and part of a jawbone and said "THIS IS PROOF FOR EVOLUTION!!!". They made an entire body out of just a jawbone and then they make piltdownman's wife!!!!!! It turns out that the bone a pigs jaw, not a ape man. This happened two other times with two other bones (I'm not going to go into them now) and all of them were proved frauds. This is just another hoax to prove this far-fetched theory.
One bitten twice shy? Science is more refined now.
Sadly, some scientist do jump to conclusions for fame. Are you blaming the whole for the acts of a few? And some are staged by people of your ilk just sour the trough.
