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]
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.
Researchers say the discovery proves the theory that some ancient human ancestors were neighbors
Two species of ancient human relatives crossed paths 1.5 million years ago. Fossilized footprints in Kenya captured the moment, according to a new study.
While there are now fossil hominins twice as old as Lucy, she remains a paleoanthropological rock star. ... I was walking on sediment 3.2 million years in age searching for the fossilized remains ...
Stone tools found at the Shangchen site in China and dated to 2.12 million years ago are considered the earliest known evidence of hominins outside Africa, surpassing Dmanisi hominins found in Georgia by 300,000 years, although whether these hominins were an early species in the genus Homo or another hominin species is unknown.

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.
