I think humans may have descended from reptiles.
wee, everything originated from the sea, that is where life began.christians say 'my grandfather wasn't a monkey and neither was his', in fact evolution takes thousands of years and is caused from genetic mutations, and the most adaptable genes will survive. the less adaptable will die off therefore leaving the more adaptable genes to reproduce, and this explains the changes in body shape, brain size everything, and explains why people are born with abnormalities because our bodies are still mutating.
There is proof, In England there is a butterfly that was dieing out because the males had a gene which caused them to die of an illness prematurely, and nature preservers all across the country gave up hope and thought it would go exstinct, when it got down to literally the last few pairs left, they found that one of the males never had the gene and was still able to mate and so eradicating the defective gene altogether, because those who had it died out and the ones that never, survived, passing their genes to their offspring, and so eradicating the bad gene altogether. Now the numbers are steadily rising.
