You seem to fundamentally misunderstand: Humans aren't from apes. Humans Are apes. Thought the categorization of animals into whatever group is indeed constructed by humans, it's not just arbitrary, or some kind of joke secretly shared among millions of scientists over hundreds of years.

I wrote this long series to help people understand and to de-mystify the complexity of the science behind it all. That is to say, just because it's too complicated for us to understand as individuals doesn't automatically give credence to doubt.

Perhaps you can start Here Where I pretty much began this series, and work your way through =)
