Humans are slightly modified apes.The evidence from genes ,as well as from anatomy,is overwhelming..The DNA in every cell in your body is a testament and witness to your close relationship to chimps.no matter how much this fact makes some people uncomfortable or upset.We know this without a single fossil human showing the transition from apes.
But how long ago did humans and apes diverge.
Using the molecular clock scientists have worked out the divergence between humans and apes to between 5 to 7 million years ago and no earlier than 8 million years ago.
