Humans are more closely related than we commonly think
Disclaimer - the last thing I want to do is to start a religious debate on HN.  So, please, don't down-vote me because I'm going to mention Bible here.
But I find it interesting that the Individual Ancestors Point is not that far off from the Biblical estimate of the Earth's age of about 6,000 to 15,000 years.
So forget about "planting" the planet with "fake" fossils, Adam and Eve are right on the same timeline as the IAP.
Which really isn't that surprising because that basically indicates the age of a modern human being, capable of passing down stories through an invention of a language, and eventually writing them down.
So, at least in this case, the Bible got the math down fairly well, and I'm bringing it up purely as a historical document here.
