A new evolutionary theory explains how seriously small early human populations survive despite the risk of transferring certain inherited hindrances to their offspring.
Anthropologists from New Castle and York University examined how their earliest au- thorities survived during periods of declining population and how they developed an early humanoid model, such as "Precise Monkeys."
In the past, in the past, a small number of people were being dragged into the land that allowed them to avoid rattles and other opponents or to benefit from emergency sources. Thus, they become isolated and form a genetic "bridgehead" that transmits the inhibitory genes.
Researchers suggest that these groups have experienced a new type of selection print. Here is not a selection for the benefit of the people with the best genes, but a selection that would benefit those who have to cope with the difficulties that their genes put on them.
Researchers also claim that our ability to show compassion and communicate, as well as to learn new behaviors by experiencing and experiencing socialization, derives from our coping strategies that allow our ancestors to overcome these genetic bottlenecks. By doing so, our ancestors turned the "obstacle", such as weak jaws, hairless bodies, short powerless arms and straight legs that could not climb to the trees, into opportunities to prepare a platform for future human evolution.

From the School of Arts and Cultures "This is a new way of thinking about 'health,'" says Nick. This is not about having good genes because half of the offspring 's genes come from one another. In such a case, the probable mating pool is extremely small and people either accept the proposed genes or never reproduce them. In some cases, close roots had become breeds that cross species boundaries in some. "
"Wherever disability pups are likely to bring to the world, the most 'healthy' individuals are those who can help their offspring with their weaknesses. A little smarter, a little more flexible and a little more compassionate would have been an advantage "
Researchers suggest that human and non-human primate races have often separated and then recombined, and that the traditional evolutionary model of evolution must be replaced by a network of separated and reunited gene flows.
From the Department of Archeology at York University. Isabelle Winder says that this work could change the interpretation of DNA records by anthropologists. "The evolutionary model of networks with parallels to other groups of animals and plants has important implications for DNA studies in anthropology."
"Molecular biologists generally explain genetic information by taking a hierarchy and statistically large populations into account. Such an approach may work for bacteria or fruit flies, but anthropological evidence can not be sequenced. It appears that humanoid populations are separated and then reunited so that small and noble molecular clocks can cause acceleration, slowing, and even backflow. "
Research published in the Internet Arcaeology magazine challenges the "Modern Synthesis" of evolutionary biology, which does not include hybridization and assumes that populations break up into isolated segments by breeding to form a constantly separated lineage hierarchy.
The father of the research team is critical of the assumption that survivors in these populations will be genetically superior to the disappearing ones, and draws attention to disabled people who are unlikely to survive without the social assistance found in archaeological records.
