Expert opinion: If the Man has modernized, it is because his testosterone level has ..

The first human beings appeared on Earth more than 200,000 years ago, but it was only 150,000 later that the first civilizations were born. Little by little, man has become civilized, learning to communicate through increasingly complex languages, using different tools and using fire, water, air and earth to facilitate Life, to become this modern earthman of the 21st century whose intellectual capacities seem endless.

But how can this metamorphosis and this evolution be explained? According to a study by Robert Cieri an American biologist and published in Current Anthropology, this is essentially due to a gradual decline in testosterone levels in individuals over the centuries. The scientist draws these conclusions following a careful comparison between a hundred skulls dating back to about 50,000 years ago, from different ethnic groups and more than 1300 others, much more recent. This comparison revealed morphological changes, particularly in the nose, eyebrows, forehead and facial length. The recent skulls show more fine lines than the old ones, even more feminine, hence the conclusion that man has only modernized when his testosterone level has dropped.
