Human beings, writes social anthropologist Ernest Gellner, are not genetically programmed to be members of this or that social order. You can take a human infant and place it into any kind of social order and it will function acceptably. What makes human society so distinctive is the fabulous range of quite different forms it takes across the ...
The Great Acceleration is the dramatic, continuous and roughly simultaneous surge across a large range of measures of human activity, first recorded in the mid-20th century and continuing into the early 21st century.
Human history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers.They migrated out of Africa during the Last Ice Age and had spread across Earth's continental land except Antarctica by the end of the Ice Age 12,000 years ago.
Diamond, who explicitly opposes racist evolutionary tales, [96] argues that the ultimate explanation of why different human development on different continents is the presence or absence of domesticable plants and animals as well as the fact that the east-west orientation of Eurasia made migration within similar climates much easier than the ...
While it is undisputed that early humans were hunters, the importance of this fact for the final steps in the emergence of the genus Homo out of earlier australopithecines, with its bipedalism and production of stone tools (from about 2.5 million years ago), and eventually also control of fire (from about 1.5 million years ago), is emphasized ...
The evidence on which scientific accounts of human evolution are based comes from many fields of natural science. The main source of knowledge about the evolutionary process has traditionally been the fossil record, but since the development of genetics beginning in the 1970s, DNA analysis has come to occupy a place of comparable importance.
Human activity – intentional, purposive, conscious and subjectively meaningful sequences of actions. Agriculture The arts – vast subdivision of culture, composed of many creative endeavors and disciplines.
Earliest development of bilateral symmetry, mesoderm, head (anterior cephalization) and various gut muscles (and thus peristalsis) and, in the Nephrozoa, nephridia (kidney precursors), coelom (or maybe pseudocoelom), distinct mouth and anus (evolution of through-gut), and possibly even nerve cords and blood vessels.
