Men, after all, may not become extinct. Y chromosome has lost only one gene in 25 million years
The ‘weird’ male Y chromosome has finally been fully sequenced. Can we now understand how it works & how it evolved?
Y chromosome bears genes that determine maleness and make sperm — but it’s also small and seriously weird
Men are slowly losing their Y chromosome, but a new sex gene discovery in spiny rats brings hope for humanity
But the evolution of the new gene comes with risks such creation of several different human species
