This story begins with the hypothesis put forward by Morton, Stone and Sikhs from Ontario (Canada). The hypothesis that they needed to explain the strange phenomenon: the female menopause. In fact, we are – living creatures – three billion years of evolving in that direction, as efficiently as possible to play in the offspring. Literally every crevice used to improve in this regard. And now here please: at the crown of the evolution of the female somehow loses its ability to reproduce well before the end of life, when she was still quite healthy and just gain experience, read too many columns on educational psychology, learned to bake tasty buns with cinnamon for kids – that kind of nonsense?
If you want to know the people, look at the depth of their own: that you are the person that you are able to understand better than anyone. It looks like our Canadian researchers – all three of them male – have followed this principle. And they found in their souls this: Buns and experience in the education – is, of course, the beautiful features of a woman, but put next to Scarlett Johansson – or for that matter, Sasha Grey – and that this governess with her buns and heart tells you which way to walk. To the left, of course. It remained to make this intuition as a rigorous scientific hypothesis.
The hypothesis was as follows: for human males have long favored young females more mature females, mature females were leaving fewer offspring. In the end, it turned out that the selection pressure – the same pressure that forces the individual to preserve their fertility – is no longer working on older females. As a result of mutation, which defined the early loss of female fertility, have ceased to be removed from the population. These mutations have accumulated. And, finally, to fix – have specific feature of Homo sapiens.
You do realize that if not selected, would we still have a handful of primeval slime, silly hodgepodge of chemicals. All that we are different from the volcanic slime won selection. A selection of works by definition, those who breed. Those who do not breed – from the Pope to Freddie Mercury – in the eyes of the evolution of dust and nothing malootlichimy from the chaos and silly to ask why they are what is, and not vice versa. It’s just a coincidence and slag.
