In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...
Research shows synthetic chromosomes can be transferred to human cells with potential to improve viral resistance ...
Neanderthals, the closest cousins of modern humans, lived in parts of Europe and Asia until their extinction some 30,000 years ago. Genetic studies are revealing ever more about the links between ...
The ape sex chromosomes have now been fully sequenced. Rapid evolution has led to extreme differences in the Y chromosome between species, whereas the X chromosome experienced much less dynamic ...
The human Y chromosome, responsible for male sex determination, has forfeited 97% of its ancestral genes over the past 300 ...
