Scientists analyze the key monogamy of evolutionary history

In general, monogamy is considered as a social and cultural practice, but a partner has a biological substance? This is said by scientists.

Is monogamy something natural? Scientists, philosophers, sociologists, and long list of specialists have requested this year. Although different positions, many times monogamy is a type of evolution, especially among mammals.

But far from any prejudice or moral attitude, why do they have a single-breed pair, for example, for men to reproduce the children's product and genetic material? Why do some animals create single-member bonds? The famous example is prairie mice (Microtus ochrogaster) All partners will continue throughout their lives.

How have you defended monogamy from science?

As explained before, there were two hypotheses: the first "advantage" is that the pair guarantees a better health for both children. Others, defended by researchers from the Cambridge University of the United Kingdom, were published recently in the journal Science, He says that monogamous couples serve to guarantee women's protection.

New study!

Recently there was an interesting research, a genetic study of the time … 450 million years! And that has made them amazing.

What did he say?

They found a universal reason for seemingly faithful species.

The document was published in the journal Academy of Sciences Academy Procedures (PNAS), when a single monogamy is conceived to create a link with a single partner, it is at least a season, because the child defends and defends work.

Important information: The researchers still do not consider animals that are still in monogamy.

What have they studied?

According to these sites, the scientists studied five species of pairs: four mammals, two birds, two frogs and two fish, each monogamy and not monogamous,

It was enough to get animals, but when they did, they had a five-fold optimal sample, and that's why monogamy became independent in the evolution of vertebrate species.

Rebecca Young, the first author of research and research at the Austin Integration Biology Department, explained:

Our research has been evolving over 450 million years ago, that is, all of those species had a common ancestral ancestor.

It has never been the time of evolution that has ever happened, but the scientists wanted to warn and take risks.

What they found …

The researchers analyzed the brain's brain in the brain of 10 species, with changes that occurred. And despite the complexity of monogamous behavior, they found that there were the same changes in gene expression. That is to say, 24 genes with significant male-like patterns have been found.

In other words, gene groups were activated or deactivated in non-monogamous species in 10 species. Genes with higher activity in monogamous species are related to neuronal development, learning, and memory.

Fresh data: scientists believe that genes capable of remembering and adjusting their brain help friends to recognize their members and enjoy their presence. Aw.

For this reason, social behaviors such as fidelity are suggested as to how the genes interact with anger.

And human beings? We do not know if we still choose fidelity because of the presence of this genetic signature, that is, in our case, it is more complex because social and cultural policies intervene. How will we really do it?
