Scientific proof: The louder the monkey's howl, the smaller its testicles

Will there be a monkey connection with those who like to ride a large car, the horns are loud and tease women?

Howler monkey (Howler monkey) was named the most massive terrestrial animal. Their buzzing sounds up to 140 decibens, equivalent to gunfire or firecrackers. Not surprisingly, the male howler uses this special ability to appeal to the howling monkey.

Recently, a scientific study published in Current Biology shows an interesting fact: The bigger the monkey, the bigger its two testicles become and the size limit.

The words "empty cries" are proved to be true in mathematics and physics, at least with the monkeys.

Specifically, after comparing the testicle size of hundreds of monkeys, a team from Cambridge University came to this conclusion.

"We found the male boar monkey with the nail bone (the horseshoe-shaped bone is located on the line between the front of the neck in the middle of the chin and the cartilage), the voice is low, usually with smaller testicles. children . " , Leslie Knapp - researcher primate and author of the study said.

"Male howling monkeys with smaller nail bones often live in larger populations of males, larger testes."

According to the research team, this is evidence that the opposite of the ability to produce sound and sperm production in monkeys.

Knapp also points out that the monstrous monkeys must always try to scream as loudly as possible to create a monopoly in the whole female population.

The study evokes the vision of big-hearted guys, big-car rides, puffs and teasing women on the road. In short, the "empty boxed" sentence was proved to be true in mathematics and physics, and now it is true for the animal world, at least the howling monkey. The "bucket" we mentioned here is the testicle.
