Genes and the
environment have an effect on human biological variation in seen characteristics, physiology, disease susceptibility, intellectual competencies, frame length and life span. Though human beings vary in lots of tendencies (which includes genetic predispositions and physical features), any people are at least ninety nine% genetically comparable. Humans are sexually dimorphic: commonly, men have more frame power and females have a better frame fats percent. At puberty, human beings develop secondary sex traits. Females are able to pregnancy, commonly between puberty, at around 12 years, and menopause, around the age of 50.
Humans are omnivorous, capable of consuming a huge type of plant and animal fabric, and feature used hearth and other kinds of warmness to put together and cook dinner food since the time of H. Erectus. They can survive for up to 8 weeks without meals, and 3 or 4 days without water. Humans are generally diurnal, snoozing on common seven to nine hours consistent with day. Childbirth is risky, with a high risk of complications and demise. Often, both the mom and the father provide care for their kids, who are helpless at delivery.
Humans have a large and relatively evolved prefrontal cortex, the area of the mind associated with better cognition. They are relatively shrewd, able to episodic reminiscence, have bendy facial expressions, self-attention and a theory of mind. The human mind is capable of introspection, personal notion, creativeness, volition and forming views on existence. This has allowed extraordinary technological improvements and complex tool improvement viable via complex reasoning and the transmission of information to subsequent generations. Language, art and exchange are defining traits of human beings. Long-distance exchange routes might have brought about cultural explosions and aid distribution that gave human beings an advantage over other comparable species.
