After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
The earliest known evidence for African H. erectus, dubbed Homo ergaster, is a single occipital bone (KNM-ER 2598), described as "H. erectus-like", and dated to about 1.9 Ma (contemporary with Homo rudolfensis). This is followed by a fossil gap, the next available fossil being KNM-ER 3733, a skull dated to 1.6 Ma. [16]
In 1972, fragmentary fossils of anatomically modern humans were found at Chouqu and Gangzilin, in Zuojhen District, Tainan, in fossil beds exposed by erosion of the Cailiao River. Though some of the fragments are believed to be more recent, three cranial fragments and a molar tooth have been dated as between 20,000 and 30,000 years old.
A new discovery of fossils dating back 1.5 million years is giving scientists fresh insight into the behaviors of human ancestors known as hominins. An international team of researchers said ...
While there are now fossil hominins twice as old as Lucy, she remains a paleoanthropological rock star. ... she was the oldest known and the most complete skeleton of an early human ancestor when ...
The brains of these early hominins were about the same size as that of a chimpanzee, and their main adaptation was bipedalism as an adaptation to terrestrial living. During the next million years, a process of encephalization began and, by the arrival (about ) of H. erectus in the fossil record, cranial capacity had doubled.
The human fossils found in the layers of sediment were originally difficult to date. Between Laotian laws protecting the remains and contaminating charcoal that had washed into the cave, several ...
The earliest evidence of fundamentally bipedal hominins is a (3.6 mya) fossil trackway in Laetoli, Tanzania, which bears a remarkable similarity to those of modern humans. The footprints have generally been classified as australopith, as they are the only form of prehuman hominins known to have existed in that region at that time. [37]
