Signed hardback copy of Professor Sykes' second book.
A Future without Men - Genetically speaking, the big difference between men and women is that where women have two X chromosomes, men have one X and one Y chromosome. It is surprising that one chromosome difference out of our total of 46 can have such an important consequence. Is this relatively small genetic variance really sufficient to explain the differences between the sexes, not just the physical but the psychological, social or even cultural? Prof Sykes takes us on a fascinating exploration into the science of sex and gender, and takes a scientific look at what makes men tick. His research has shown that the all-important male Y chromosome is getting smaller. As the generations pass the female X chromosome is taking over. Women are winning the evolutionary battle of the sexes. The shocking conclusion is that men, slowly but surely, are headed for extinction.
