Biologists have shown the benefit of severe childhood for future generations
Mouse-males, whose early childhood was spent in a stressful environment, gave birth to offspring that were different purpose, is also an excellent ability to adapt to changing conditions. About the benefits of children's suffering for future generations described in the journal Nature Communications.
Isabelle Mansuy (Isabelle Mansuy) and her colleagues for 2 weeks had weaned calves from mothers and immediately created for the last stressful conditions. Later, mice were returned to their parents. Further, the descendants of these survivors of traumatic experience males were more effective many behavioral studies. Individuals turned out to be more purposeful and adaptive.
And yet scientists have reported that the latest distinguishing features of behavior was accompanied by epigenetic changes in the gene responsible for mineralcorticoid receptor. This substance, as it has long been known, plays a significant role in the stress response.
Most animal experiments have demonstrated that severe stress in the 1st week of life have a negative impact on the lives of individuals: immunity decreases, becomes more desperate behavior, cognitive abilities fall. However some studies have found that transferred after birth stress gives some superiority in the later stages of life. And, in the end, scientists noticed that the useful results of the stress transmitted by inheritance.
