Because of the way reproduction works we inherit mitochondrial DNA from our mothers, and males inherit their Y chromosome from their fathers. As errors occur in each generation comparing mitochondrial DNA will tell you how closely related to someone else on the maternal line and we all appear to be related to one "Eve" line about 200,000 years ago - which is about when the modern human species first appeared in the fossil record. On the paternal side it was recently believed that us males shared a common ancestor about 60,000 to 140,000 years ago.
But that was before someone sent a sample from Albert Perry to a genealogical testing lab. If you are interested in DNA testing - or in human evolution - see "Why is Albert Perry's DNA si interesting?" on my other blog.
One of the reasons this Newsletter has not been so busy recently is that I have been spending more time "Trapped by the Box"!
