Modern human DNA contains bits from all over the Neanderthal genome, except the Y chromosome. What happened?
Neanderthals, the closest cousins of modern humans, lived in parts of Europe and Asia until their extinction some 30,000 years ago.

The Y chromosome is a never-ending source of fascination (particularly to men) because it bears genes that determine maleness and make sperm. It's also small and seriously weird; it carries few genes and is full of junk DNA ...

All around us, insects are speaking to each other: jockeying for mates, searching for food, and trying to avoid becoming someone else's next meal. Some of this communication is easy to spot—like the flashes of fireflies ...

The sex of human and other mammal babies is decided by a male-determining gene on the Y chromosome. But the human Y chromosome is degenerating and may disappear in a few million years, leading to our extinction unless we ...

In mammals, the distinction between male and female at the chromosomal level is due to the X and Y chromosomes. Typically, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY). The Sry gene on ...
