Mysteries of human reproduction
Although nothing is more natural than the reproduction in humans as in any other life form, does not mean it’s simple. Very basis of living matter, essential for the perpetuation of the species, reproduction is a process of bewildering complexity and as we deepen the study’s more, the becomes overwhelming. And if our species, in addition to “the usual” unknown cellular and molecular mechanisms of this phenomenon, there are a number of specific human enigma that human reproduction differ from that of many other mammals and make it, in many respects, a bizarre phenomenon. Here, explore a brand new book, some primate reproductive oddities, some of which are “exclusively” human species for which there is still no solid explanation, but assumptions.
The book that will appeal to guide us through the twists and turns of human reproduction, from an evolutionary biolgică and is called How We Do It: The Evolution and Future of Human Reproduction; its author, Robert Martin, is a noted American researcher specializing in the study of breeding primates – the mammalian order to which they belong and the tail monkeys and man. Robert Martin is a member of the Committee on Evolutionary Biology at the University of Chicago and responsible biological anthropology research in the Field Museum, in the same city.
40 years of studies on primate reproductive helped prof. Martin to understand the complexity of this process, to discern the particularities of the different species of primates and thus to understand in what respects are and what matters differs reproduction human species from other species more or less closely related to us. Here are some of the issues discussed in his book – surprising aspects related to the composition of the human reproductive system, reproductive physiology, pregnancy and childbirth – and convince us that man is unexpectedly similar to many other primates, but that does not always helps to know and understand their reproductive biology, which remains in many ways mysterious.
Why people are “wasting” sperm?
Here’s the first oddity: why, during life, a woman produces only a few hundred eggs, while a male produces sperm trillion? For each egg produced by a female in the menstrual cycle (period between two successive menstruation, which includes a series of changes that occur in the ovaries and uterus for possible pregnancy), the man who tried to fertilize do this “mission sending “hundreds of millions of sperm in each sex. A method of reproduction seems very expensive and inefficient! Why such a waste of sperm?
Short answer and sec is “not known.” Answer funny – a joke cited by the author in the book – is “because none of them stops to wonder which way to turn.” A response-hypothesis is that perhaps the best solution to this problem was simply organic to create a large egg to be a stationary target for a lot of sperm that are moving towards it.
Joke or not, the fact is we do not know why the development of such right things, and not only to us but to other species of primate and non-primate mammals even.
