Now, researchers have identified the genes that helped early humansadapt to eating plants and new animals as they conquered the world. Variants of genes, which are involved in the digestion of fat, were keyto help human beings thrive in extreme environments. And a new analysis of the genes suggests that Europeans still can be adapted to adiet based on agriculture. The genes, known as FADS1 and FADS2, are enzymes involved in the digestion of fatty acids. Professor RasmusNielsen, of the University of California, Berkeley, told Satan that genes could have helped our ancestors to adopt a lifestyle more mobile.' the authors who originally observed this pattern in Africa suggested that it could be caused by a switch from a diet high in animal fat, alternative diets that allow human beings to greater mobility and linked to Marina sources and could therefore linked to the expansion of theanatomically modern humans in Africa makes some 60,000 to 80,000years. ' PLANTED genes seem to have been white frequent natural selection throughout the history of humanity as our diet has changed as a result of the new hunting or agricultural practices ', said ProfessorNielsen.As early humans moved into new environments, strong natural selection acted on PLANTED genes, according to researchers. "It has changed in various ways in different parts of the world," said Professor Nielsen.' in general, see selection favoring alleles associated witha diet rich in animal grease outside of Africa, most so that within Africa. 'Possibly, as modern humans outside of Africa, mammals were found with new opportunities for big hunting.' Natural selection favored the mutations in genes that helped early humans to digest new food groups. While those who possessed the variants of genes were able to assimilate new foods, to survive and have children, those who did not have the favorable genes of fashion died out. Mutations in thegenes of fashion have been key to help the Inuit adapt to a diet rich in fat. Inuit have adapted to eat marine mammals such as walruses, seals and whales, which are protected from the cold by a thick layer of fat. And variants of favorable trends also helped humans adapt to a vegetarian diet in the India. As part of the study, the researchers compared genes of fashion 101 skeletons of the bronze age to the Europeans of today. They found that the genes from the vagaries of the Europeans have changed to adapt to a grain-based diet. 'our study shows that there has been a new transition in Europe, where a vegetarian diet-related alleles have been favored, probably due to the emergence of agriculture and the switch to a vegetarian diet,' said ProfessorNielsen. But they suspect that Europeans today continue to evolve toadapt to changes in the diet. 'We hypothesize that the Europeans may be in the process of adaptation to a diet rich in fatty acids derived from vegetable sources, but relatively poor in fatty acids derived fromfish or mammals,' said Professor Nielsen. agricultural diets 'introduction and spread of agriculture in Europe probably produced a radical change in diet in populations that have adopted this practice.' would have led to a higher consumption of grains and other foods of vegetal origin, in relation to the populations of hunter-gatherers.' THE GENES OF FASHION
The genes, known as FADS1 and FADS2, are enzymes involved in thedigestion of fatty acids. FASHION stands for the fatty aciddesaturase. Genes have interested scientists because they have beenkey in helping the primitive humans adapted to eat plants and new animals as they conquered the world. As early humans moved into new environments, strong natural selection acted on genes of fashions.Natural selection favored the mutations in genes that helped early humans to digest new food groups.
While those who possessed the variable gene variants were able to assimilate new foods, to survive and have children, those who did nothave the favorable genes of fashion died out.
