The palaeolithic diet and the unprovable links to our past

Sex, genes, the Y chromosome and the future of men

The Y chromosome, that little chain of genes that determines the sex of humans, is not as tough as you might think. In fact, if we look at the Y chromosome over the course of our evolution we’ve seen it…
