Early adverse experience as a developmental risk factor for later psychopathology: evidence from rodent and primate models.

«The higher levels of these proteins in human milk are consistent with the well - established perspective that human babies, compared to other primate infants, are born at a slightly earlier stage of development and require higher levels of specific proteins that will nurture them as they mature,» Lemay said.

In tamarin primate families, the males care for the babies from an early age, providing as much, and sometimes more, care than the females.

Because this behaviour is encoded in the same region as in other primates, it may be there from birth or earlier, the researchers say.

In addition to being the oldest known example of an early primate skeleton, the new fossil is crucial in elucidating a pivotal event in primate and human evolution — the evolutionary divergence that led to modern monkeys, apes and humans (collectively known as anthropoids) on one branch, and to living tarsiers on the other.

«The tiny size and very basal evolutionary position of Archicebus support the idea that the earliest primates, as well as the common ancestor of tarsiers and anthropoids, was miniscule.

Therefore, tooth - combed primates probably did not originate as early as molecular biologists have claimed.

A fossil that was celebrated last year as a possible «missing link» between humans and early primates is actually a forebearer of modern - day lemurs and lorises, according to two papers by scientists at The University of Texas at Austin, Duke University and the University of Chicago.

It doesn't, however, present the fossil as «the missing link» — a direct bridge between humans and early primate ancestors.

Under the proposed NIH policy, taxpayer funds would be allowed for experiments in which human cells are added to early - stage embryos of all animals except nonhuman primates, such as chimpanzees and monkeys, because they are so similar to humans.

The Broken Hill skull is the first early human fossil found in Africa and provided the primary evidence to support Darwin's theory of evolution, proposing humans as the natural descendants of primates.

Stress regulation in children is important for understanding the development and prevention of psychiatric disorders.1 Environmental factors that operate at key points in development may shape affective and behavioral regulation and hypothalamic - pituitary - adrenal (HPA) axis function in children, much as environmental factors have been shown to shape HPA regulation in rodents and nonhuman primates.2 Early experiences in rodents exert lifelong organizing effects on stress responsivity.

Early life stress as a risk factor for mental health: Role of neurotrophins from rodents to non-human primates

Interestingly, nonhuman primates subjected to early abuse and deprivation also are more likely to engage in violent relationships with their peers as adults.134 as in humans, males tend to be hyperaggressive, and females fail to protect themselves and their offspring against danger.
