Revealing the truth from 7,000 years ago, why every man must take 17 wives

According to research by scientists, until the time of 5,000 years ago, the number of men on Earth began to recover. During the previous 2,000 years, the number of men was so small that no one had to be alone in the world, so each guy had to take . 17 wives.

The above situation occurs when the Earth population is estimated to reach a maximum of 20 million people. The law of reproduction does not change, the number of boys and girls born is equal. However, an imbalance occurs when about 9.5 million men die young.

Stanford University scientists (USA) explain, this is the result of constant competition between clan groups in Europe, Asia, Africa and the Middle East. They found surprising biomarkers, through archaeological evidence. By the time 7,000 years ago, humans had grown to a level sufficient to generate competition between community groups and the Earth was crowded enough for clans to clash.

As previous studies, 12,000 years ago, society began to evolve from nomadic hunters to agricultural communities. They suddenly became aware of property ownership . Clans find settlements stable and do not welcome intruders. Resources are finite, from which conflicts arise.

In the battles, this group's goal is to destroy all the other men of the group to eliminate the losing power of the losing team. And for 2,000 years men have killed each other until the world is almost entirely women.

Scientists call this event "World War Zero". Fortunately, when women become overcrowded, clans have found a way to live more peacefully and gradually restore humanity.

Not long ago, scientists had studied that men would become extinct due to reduced chromosomes. Accordingly, studies conclude that the Y chromosome of male sex determination about 200 million years ago contained up to 800 genes but with time, currently, the number of genes in the Y chromosome is only 30.

The results of this study raise concerns that the remaining 30 genes will disappear at some time in the future. The Y chromosome is no longer available, meaning that men will become extinct.

"Will the Y chromosome disappear?" - This question has made the world scientific community divided into two factions: trust or protest. The protesters argue that the "gene amplification" response mechanism is doing a good job of protecting its degradation. The other group is relatively pessimistic, believing that this mechanism only It's like the "last step" for Y, before disappearing completely.
