Questions… and answers

Do you think that:

The human is the fattest primate

  • Because her baby is born helpless, that ‘s why he needs heat, and the adipose layer, which is considerable against those existent to the other kindred primates, has the role of protecting him of cold in the savannah ? (the official variant in science at this moment)

Mayr, E., „De la bacterii la om- evoluţia lumii vii „, Humanitas, 2004 p.308-309

  • or because there was a time in her evolution when she lived in a semi aquatic environment, and marine mammals have a considerable adipose layer which they keep the whole year, not seasonal, like animals which hibernate (the aquatic theory of humanization, unofficial, contested in science) ?

The human baby is so helpless compared to the baby of other primates

Because selection favoured a bigger brain, in fact the intelligence it supposed? The brain increased a lot before birth, but its increase was possible until one point. That point was represented by the birth channel, limited by the bipedal walking; meaning that if it had been bigger, then the ability of walking bipedal would have been affected. Then the baby is a premature with 17 months, continuing his increase with a pace similar to the one in the intra uterus life, in fact continuing his intra uterus life after birth, reaching subsequently the development stage that the chimp cub has at birth.

The size of human increased from Australopithecines, to Homo genre (Homo erectus) and then to the present human

is it also because of brain increase? For a bigger brain, the baby was bigger, that ‘s why mother became bigger. She became bigger in order to have the strength to hold her baby in her arms. This is also the cause for the fact that sexual dimorphism (in this case the difference of height between females and males) decreased in comparison with Australopithecines.

Human lost her fur

  • to defend herself against parasites? Mammals without fur have fewer parasites.

Pagel, M. and Bodmer, W. „A naked ape would have fewer parasites „, Proc Biol Sci. 2003;270(Suppl 1): 117 “119 doi: 10.1098/rsbl.2003.0041.

Or, the older variant

  • for the helpless baby to receive easier her mother ‘s heat?

Mayr, E., „De la bacterii la om- evoluţ£ia lumii vii „, Humanitas, 2004 p.308-309

Human lives more than chimp

  • because she needs more time to study. A selection factor was given by hunting, whose practice is difficult and required several decades to assimilate. This means that human lives more because learning hunting selected the individuals who live longer; by this they were better hunters. To compare, Albert Einstein was 26 years old when he started to teach others the Theory of Relativity, although nobody taught it him

Finch, C. E.,. Stanford, C. B. „Meat-adaptive genes and the evolution of slower aging in humans „, The Quarterly Review of Biology, March 2004; 79 (1)

Human has a slower development, a slower maturation, in other words, a slower life compared to the chimp

  • because a slower development is related to a bigger brain? Indeed there are certain correlations between the two phenomena. But the slower development permitted longer learning, accumulating knowledge for longer time.

Morris, D., „The naked ape: A Zoologist ‘s Study of the Human Animal ” McGraw-Hill Companies, 1967

And if you think that this is it- let’s see another idea

Menopause appeared to human

  • for grandmothers to dedicate to grandchildren ‘s education, teaching them to gather roots (although the fitness increases, meaning the ability to have viable descendants must be the result of natural selection, the selective advantages are measured in this)? Theoretically, indeed, investing in grandchildren of other relatives leads to the survival of their own genes, but the education of a child must have been then extremely expensive

Hawkes, K., et al., „Grandmothering, menopause, and the evolution of human life histories ” Proc Natl Acad Sci U S A 1998;95:1336-1339

Do you want a theory which answers all these questions at the same time? And in several phrases, (in fact in several words, phrases come to explain) without hypotheses and supportive postulates? If you don ‘t give evolution another chance, you can find this in „Civilization of famine/ the human evolution seen from another angle „. 100% Evolution. Still, it is a new science; Darwin ‘s theory has just reached 150 years from publishing. If medicine was so young, we would still recommend bleeding for all kinds of diseases. We should give a chance to a science that is still young, but it shouldn’t remain young. It ‘s time ˜antibiotics ‘ were invented in evolution too.

This book will be soon available in English.
