How do you know that some people didn't have hairy babies...then their hairy offspring bred until apes evolved?
You realise what you are saying here, Shan? You are saying is is possible that apes (in other words, different species or
kinds ) can evolve from humans. If this is the case then there is no way you can claim there is any barrier to other species evolving into humans (or anything else for that matter). In other words, your question implies what you creationists like to call macroevolution.
