Continuation of the debate last week, this article will seek to investigate whether human procreation is a product of evolution, and in what proportions, which is to undergo cosmetic surgery procedures that will be experienced by men and women. Basically in this article I will proof in three phases to be considered:
Everything is like our evolutionary heritage of our ancestors, primates, as inferred from our closest primate relatives?
· What are the major evolutionary events separating us from our closest primateRelatives?
· How can we expect these events is to our evolutionary patterns of reproduction and transformation that is reflected in the cosmetic surgery procedures?
Sex among the primates
There is no uniform code of sexual behavior in our closest primate relatives. Gorillas, chimpanzees and bonobos all "do it" differently.
Gorillas are less closely than the other two together, but they offer an instructive contrast. Male gorillas keep harems with a small group ofEngaging women sexually strictly controlled by a single dominant male. Competition among males for dominance is fierce, but with the final rule, men and their harem live in isolation from other families. The consequence is that male gorillas large, muscular body to have, while female gorillas are much smaller and with little signs of reproductive receptivity.
Chimpanzees and bonobos are similar, but much reproductive patterns. In both species,Women show openness towards reproduction with swelling of the genitals. Are also in the two types of women generally promiscuous, even though chimpanzees are more women than men are, the pair bond, even if for a short time.
Human Touch
People are much different than our ancestors, primates, from which we separated by three major evolutionary changes:
· Bipedalism
· Larger brains
· General hairlessness
How these three possibleChanges have affected human reproductive patterns?
Bipedalism is the first evolutionary change that separates humans from other primates, the five to six million years ago, when the australopithecines differed from the ancestors of chimpanzees and bonobos. Bipedalism would be expected to create many changes in sexual selection. First, the presence of large, muscular buttocks, an inherent side-step our position is, if reading from their ancestors lived in swelling thatreproductive signaled openness as a sign of the continuous recording standby.
This effect would have been most pronounced among our early ancestors who had changed between a bipedal and quadrupedal stance, both increasing muscle mass, his head down to where the signal would be read.
This pattern is created during the transition phase, the signal will be missed if our ancestors were in full on two legs, with less visual contact with the signal so that aDesire, ie a sexual selection pressure in favor of the signal comparable to some extent more fully visible while standing. Enter the unusually large human female breast. As an unusually large? Consider this comparison with our nearest primate relatives.

Note also the relatively large penis of the male people who are also following bipedalism, making the penis would be elected easily visible. If men were standingto expect sexual selection of women for a larger penis, although the role of the larger penis is more likely to Male display male dominance battles than sexuality.
One can also expect that will increase the signals of bipedalism facial area, leading to greater selectivity in terms of facial shape and expression.
Larger size of the brain seems to have both a driver and a response to use tool for our early ancestors, which were rapidly accelerated througheven other primates, our ancestors found themselves with free hands.
The larger size of the brain had a negative effect on the human side of birth, already by the changes in the pelvic area caused by bipedalism tense. To understand the difficulties in transferring the child by the big brains behind the vaginal opening pools, human women who would meet her children at a slightly earlier stage of fetal development had a higher survival rate, eventually leading to the currentSituation in which people the birth of a child whose brain is only 29% of adult size compared to chimpanzees, which give birth to children, whose brains are almost 50% that of the adult size.
The cost of premature birth? Human children are helpless at birth than any other animal, including the marsupials. Anyone who has a child who knows what that means months or even years of dedicated service. How could a woman be expected is for a child during the leadership of the lives of our extensiveAncestors have led to foot in every corner of the world to spread? She would need help. Could it help to get from other women, but our closest primate relatives, jealously guard their offspring out of the hands of other women, so this seems an unusual source of help for early humans. So where a woman could help in caring for their child? In its mate.
Human men put a lot of work in the education of their children, not only in terms of food and shelter, butone-time investment. But in order for a woman in a position to disclose the investment strategy of the man, the woman and the man must expect seamless bond that may be appropriate, the five or six years, the old for a human child enough to go last, and contacts to make are to be bound by a peer group for the protection.
To support this commitment to the people developed a complex series of mating rituals for the display of pre-and post-sex sex emotional attachment. All cultures that share. Most of these rituals include face-to-faceCommunication, both verbally and nonverbally about appearance and by kissing and touching the bare skin. Develop skin-to-skin contact with the medium through which people began to what we are today, "erotic love." As an integral part of the susceptibility to erotic love, the bare skin was a desirable quality in men and women, creating a feedback loop of sexual selection, to the almost complete loss of hair from the members of both sexes.
Cosmetic Fallout
If thisAccount of sexual selection in human evolution is true, we would expect that many people try and avoid false indicators of a positive change in the genome, ie, they would want to look beautiful in a way that had been sexually selected in our evolutionary history. In other words, we would expect cosmetic surgery procedures to the center for about three loci:
To distinguish between 1) the chest area, male and female sexual dimorphism;
2) The face to improve the signalHealth
3) hairlessness and healthy skin.
Let's see if this is the case.
According to statistics from the American Society of Plastic Surgeons (ASPs), the surgical procedures directed at a specific area of the body other than the face, were judged 72% of the chest, under the direction of breast augmentation and breast lifts for men and breast reduction in men. About 58% of all cosmetic treatments were addressed in the facial area, including eyelid surgery, facelifts, rhinoplasty,and a variety of facial injections, mainly cosmetic Botox. In addition, most other applications for the management of hair and gives skin a healthy and youthful appearance given by microdermabrasion, laser skin resurfacing, laser hair removal and obliteration.
So it seems that evolution has in fact affected human sexuality, which means that we are left with the mystery of why the females of our species and not the men who are so devoted to ornaments. Althoughone could argue that men means investing heavily in children, the incredible toll that takes a woman giving birth that women invest still more, why, then women would be so much more ornamented than men? We will investigate this issue further in the next installment.
