On the arm of Swiss tennis player Stan Wawrinka is tattooed a quote by Samuel Beckett: “Ever tried. Ever failed. No matter. Try again. Fail again. Fail better.”

Over Christmas, vegetables, bananas and insulation foam washed up on beaches along England’s south-east coast. They were from 16 containers spilled by the cargo ship Baltic Klipper in rough seas.

“Size matters” sounds like a tabloid cliché, but for evolutionary biologists the size of the human penis is truly a puzzle.

Compared to other great apes, such as chimpanzees and gorillas, the human penis is longer and thicker than expected for a primate of our size.

If the primary role of a penis is simply to transfer sperm, why is the human penis so much larger than those of our closest relatives?

Our new study, published today in PLOS Biology, reveals a larger penis in humans serves…The Conversation (Full Story)
