The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage. For the earlier history of the human lineage, see Timeline of human evolution#Hominidae, Hominidae#Phylogeny.
The evolution of eukaryotes, and possibly sex, is thought to be related to the GOE, as it probably pressured two or three lineages of prokaryotes (including an aerobe one, which later became mitochondria) to depend on each other, leading to endosymbiosis. Early eukaryotes lost their cell walls and outer membranes.
The illustration is part of a section of text and images commissioned by Time-Life Books for the Early Man volume (1965) of the Life Nature Library, by F. Clark Howell. [4] The illustration is a foldout entitled "The Road to Homo Sapiens". It shows a sequence of figures, drawn by natural history painter and muralist Rudolph Zallinger (1919 ...
The authors argue that many of the basic human adaptations evolved in the ancient forest and woodland ecosystems of late Miocene and early Pliocene Africa. Consequently, they argue that humans may not represent evolution from a chimpanzee-like ancestor as has traditionally been supposed.
The earliest known fossils of anatomically modern humans such as the Omo remains from 233,000 to 195,000 years ago, Homo sapiens idaltu from 160,000 years ago, and Qafzeh remains from 90,000 years ago are recognizably modern humans. These early modern humans possess a number of archaic traits, such as moderate, but not prominent, brow ridges.
While the human body clock is a complex trait shaped by social and cultural norms as well as genetics, Neanderthals, who evolved at high latitudes in Europe and Asia for hundreds of thousands of ...
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.
This is a list of dates associated with the prehistoric peopling of the world (first known presence of Homo sapiens). The list is divided into four categories, Middle Paleolithic (before 50,000 years ago), Upper Paleolithic (50,000 to 12,500 years ago), Holocene (12,500 to 500 years ago) and Modern ( Age of Sail and modern exploration).
