Abstract sex differences in brain and behavior of animals including humans result from an interaction between biological and environmental influences. Male birds particularly, for example roosters, tend to have physical features that differ from the females and also differ significantly in size. This is also true for the differences between men and women concerning sexual orientation.

Sexual differentiation is mediated by three groups of biological mechanisms: Sex differences in appearance are often more pronounced in nonhuman animals than in humans. Early actions of sex steroids, more direct actions of sex-specific genes not

Human and animal sexuality have certain elements in common, but also many differences.

In fact, it couldn't be otherwise, taking into account that human beings are immersed in culture and civilization, two symbolic realities that are absent in the animal world. This means that human sexuality is historical, unlike in the animal world. Therefore, the way we think of sex and the way in which All behav-ioural differences in animals and humans develop under two major types of influence:

Biological factors including mostly genes, their expression and hormones, and environ-mental factors recovering multiple forms of influences of parents, peers and congeners, in general, associated with various forms of learning. There is no human counterpart to lordosis (at least not as an unambiguous, estrogen-dependent postural display of sexual receptivity in females), and human sexual behavior is so shaped by experience and learning that it seems to defy hormone actions that are critical to the display of animal sexual behavior. This despite the scientific evidence showing that sex differences in physical aggression are universal across human societies, have a cogent evolutionary rationale, manifest in most other mammalian species, and have well-worked-out biological mechanisms. Sex differences in appearance are often more pronounced in nonhuman animals than in humans.

Male birds particularly, for example, roosters, tend to have physical features that differ from the females and also differ significantly in size.

The researchers also found that, in all animals and humans, few sex differences occurred while organs were developing. Instead, they increased sharply around sexual maturity. We caution that the costly imposition of sex analysis on nearly all animal research entrenches the presumption that human brain and behavioral differences are largely biological in origin and overlooks the potentially more powerful social, psychological, and cultural contributors to male-female neurobehavioral health gaps. A large number of morphological, physiological and behavioural traits are differentially expressed by males and females in all vertebrates including humans.

These sex differences, sometimes, reflect the different hormonal environment of the adults,
