British scientist Steve Jones (no relation to the ex-Sex Pistols guitarist) claims in his new book Y: The Descent of Men that human males don’t have much of a future. Not only have average sperm counts declined in recent decades, but the Y chromosome itself is slowly but irrevocably devolving into uselessness. The result, as Jones tells Britain’s weekly Observer: “‘The chromosome unique to men is a microscopic metaphor for those who bear it,’ Jones concludes. ‘For it is the most decayed, redundant and parasitic of the lot… From sperm count to social status, and from fertilisation to death, as civilisation advances those who bear Y chromosomes are in relative decline.’… ‘the Y chromosome will eventually disappear and be taken over by another sex-determining mechanism.’
