Phylogenetic Trees

I’ve created a couple of phylogenetic trees using the very helpful online utilities at Dean McGee’s McGee Surname DNA Project web site. A phylogenetic tree is a pictorial representation of the relative relationships among different branches of a genetic family. Remember, this is not perfect. It’s a mathematical approximation of who is most closely related to whom, based on the number of differences in the mutations, using known mutation rates. Some people may be more closely related than indicated and some may be farther. Mutations are random occurrences, so we can only deal in probabilities.

Because the extended tree (on the left) is so big, I did not fill in all the dates at the nodes. But here is a link to a table of probable TMRCA (Time to Most Recent Common Ancestor) to help you interpret the data.
