XXXX man

Most mammals have it.

Dogs, bats, walrus and most monkeys - what connects the males of these species?

They all have a bone in a sensitive place: the penis. What made the human skeleton lack an internal "stiffener"? Are we losing something?

Although this may seem unlikely, most mammals have an additional bone with an elegant Latin name baculum. The mysterious element of the skeleton is usually located at the base of the male penis of most mammalian species - from bears to bats. It may have a residual form and size of the nail, but in some cases it reaches a large size - the baculum of the walrus measures up to 60 centimeters. The dice of the penis are deprived of some species of monkeys, rabbits, pounding, elephants, hyenas. And people.
