Men over the next 100,000 years die,






Declared a science complete extinction within the next 100,000 years male Homo sapiens as a species will not take place.


To such conclusion scientists from the U.S. Institute for Biomedical Research ( Mass. ), ITAR -TASS.
The output of the impending disappearance of the men was taken at the beginning of the last decade a number of specialists who have studied the unique Y-chromosome. It is present only in men and is responsible for the birth of boys.
As it turned out, at the time of the appearance of Homo sapiens Y- chromosome gene was 1400. However, modern men, it has only 45 genes. According to the steps of the 2003 estimates, the man remains survive as a biological species from 100 thousand to 5 million years, depending on the speed of further extinction of genes in the chromosome. Cause of the rapid expansion of the Y-chromosome, scientists named it highly vulnerable to environmental changes.
However, U.S. scientists have refuted these findings. After studying the dynamics of the biological development of monkeys and humans, they concluded that what happened to reduce the number of genes in the Y-chromosome does not affect its function and stability. Moreover, the scientific staff of the institute concluded that the historical and biological process of decomposition of Y-chromosome has ceased.
... - Those genes that are in it now and will remain in the structure of chromosomes ...
