brantgoose: You'd be surprised how many of your genes you share with your dog. Or with mice (about 50%). Or even with bananas (25%). I suspect that American and Canadian poltiicians are mostly bananas.Since the advent of genetics and gene replication on a large scale, scientists have been using mutations in genes shared by humans or shared with other species to not only track the movements of people in prehistory, but also to figure how how closely species are related to each other.The gene clocks (such as the Y-chromosme and mitochondrial DNA) may run at different speeds, but the mutations do occur with regularity, which enables scientists to build a family tree for humans and for life in general.I've been reading books genetics and genealogy lately, especially the British population, since they are covered in the most detail.It is complicated and fascinating, but much has been and can be learned.There is a lot of misunderstanding among the general public, however, of what all this means. This is particularly true of nationalists and racists. They think the genes can be used to support their favourite prejudices. Not so.Take my Y-chromosome, please!Oops! That is ruder than I intended.But seriously, the Y chromosome is used to track the movement of men (through war, trade, slavery, etc.). All men have one, and only men have them. They have 17 genes, one of which turns a girl fetus into a boy fetus at six weeks after conception. That is all it does. The other 16 genes are largely involved with sperm production and quality. That is all they do.But you can use the junk DNA (non-coding for proteins and apparently largely used only for spacers in the gene code) to track the ancestry of men.All men have a lineage consisting solely of men--their father, paternal grand-father and so forth. All women have a lineage consisting solely of their Mother, their Mother's Mother and so forth. These two lineages are the only ones consisting entirely of one sex or the other. A ...
