Spiky Penis mystery solved



Researchers at Stanford University in California think they’ve identified how humans lost the spikes our ancestors had on their penises. It’s thought the loss of a particular bit of DNA that controls a hormone gene is likely to be behind the change. It was believed the spines were used to remove the sperm of competitors who had mated with a female. It’s thought that the loss would have reflected a more monogamous reproductive strategy.
