evolution: both men lost their "masculinity"

In a race of human evolution has bypassed the monkey, "paid" for the increase in brain penisovoy loss of bone. Not a bad replacement, or so-so? Those men who answer "so-so" really have a reason to take offense at the evolution that has been selected bakulyum (penisovuyu bone). And it certainly would be very useful to them, once present in many mammals, in particular, almost all primates, including the closest relatives of human - chimpanzee.
All other members of the sterner sex to inform you that according to research conducted by David Kinglsi and his colleagues at Stanford University (California, USA), loss of bakulyuma, which provides a permanent male "combat readiness" is a realistic price for the opportunity to go far ahead in evolutionary terms from relatives in the image of the primates. Research reports were published today in the journal Nature News.
By the way, the scientists who have made this discovery was not studied comparative anatomy of man and ape. Theme of their study was much broader and deeper - namely, how we differ from apes at the molecular level. They used a unique approach. They are looking for is not what a man can have, and no monkeys, but on the contrary - that they have, and we do not have. As a result, it was found 510 DNA sequences present in the genome of the chimpanzee and man have been lost during evolution. Almost all the detected sequences belong to the so-called non-coding regions of the genome. These areas do not contain information about any protein. However, they can affect the "protein" (coding) DNA band, lying in close proximity. As a result of the influence of protein production from these adjacent areas may inhibit or increase.
Two of the identified regulatory DNA sequences located near the androgen receptor gene and a gene that is responsible for the suppression of tumors. Once the DNA into the genome controls implanted in experimental animals, it was found that the first of a series of controllers stimulates the formation of just the very bones in the penis, as well as the growth of whiskers. But it is not our usual "human" and sensitive "cat" the antennae, called vibrissae.
The second DNA sequence is even more interesting. In short, her loss has enabled man to increase the brain. Because the gene that makes tumors grow, and its regulatory sequences present in monkeys, but suppresses tumor growth and nerve cells in the brain.
Given that examined only 2 of 510 DNA sequences of monkeys, it is difficult to imagine how much more molecular evolution "surprises" we can get.
The international scientific community has appreciated the opening of American Scientists. After all, it was the most obvious confirmation of the hypothesis that evolution - it's not just the accumulation of information, but also periodically to get rid of disturbing, unnecessary data.
