200,000 years ago: Modern humans (Homo sapiens) evolved in Africa; they gathered and hunted food, like earlier human species. The date of 200,000 years is based on the oldest known H. sapiens crania and the estimated age of convergence (back in time) of all the mitochondrial DNA diversity recorded in living human populations.

To celebrate the 150th anniversary of the Origin of Species, here's a list—by no means exhaustive—of some of the biggest advances in evolutionary biology over the past decade. These advances include not just a better understanding of how this or that group of species first evolved, but insights into the evolutionary process itself.
Robust hip bone and lengthened thigh bone indicate that human ancestors could walk farther, faster and more easily. By 1.8 million years ago: Early humans dispersed from Africa to Asia. By 1.6 million years ago: First major technological innovation. Hand axes are made. Hand-axe technology persists for more than 1.2 million years.
See Article History. Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed zoologically, we humans are Homo sapiens, a culture-bearing, upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
But in the late 1900s, evolutionary biologists began to detect small but significant changes taking place in a handful of species. In the past decade, many more cases of natural selection have come to light, and scientists now realize that species can adapt quickly to changes in their environment.
Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
The typological system used by Morgan and Tylor broke cultures down into three basic evolutionary stages: savagery, barbarism and civilization.
Edward Tylor, one of the main scholars in the field of early cultural evolution, asserted that all cultures moved up almost a ladder of progression through three main stages of progression, which were savagery, barbarism, and civilization.
The two effects of dividing food-gathering labor, the camp and the dependence of the sexes on each other beyond reproduction, were the first great steps toward modern human culture. Sharing of resources and its concomitant division of labor led to a divergence in both the biological and cultural evolution of the sexes.
Humans acquire culture through the learning processes of enculturation and socialization, which is shown by the diversity of cultures across societies.
TylorTylor maintained that culture evolved from the simple to the complex, and that all societies passed through the three basic stages of development suggested by Montesquieu: from savagery through barbarism to civilization.
Stages of Evolution of Man. The family to which human beings belong is called Hominidae. It was in the Miocene age that the family Hominidae split from the Pongidae(apes) family. Dryopethicus was the first in the evolution of man in the stages of evolution and some believe him to be the common ancestor of man and apes.
1. Introduction. Fire is universally accepted as important to human life, with myriad expressions and uses in the modern world [1–7]. It was regarded by Darwin as the greatest discovery made by humanity, excepting only language [8].
cultural evolution, also called sociocultural evolution, the development of one or more cultures from simpler to more complex forms. In the 18th and 19th centuries the subject was viewed as a unilinear phenomenon that describes the evolution of human behaviour as a whole.
The study of the evolution of the human species can provide insight to understanding the violence, aggression and fear around us today. Humans have evolved as social, empathetic, collaborating and altruistic beings in small groups sharing common identities.
