  • Holmes talks about the Y chromosome. Claims of its impending demise are starting to look premature, however. Far from being a rotting husk, the modern Y, tiny though it is, is turning out to be a highly evolved and surprisingly important part of men's wider genetic endowment, responsible for far more than just maleness. It is easy to see why some biologists thought the Y was destined for oblivion: it is all on its own. But even though it has lost almost all of its original set of genes, it has gained others: 61 of the human Y's 78 genes were not present before the first inversion took place.
