First human ancestors to live on the savannah So far, scientists have been unable to detect the sudden “moment” of evolution for any species, but they are able to infer evolutionary signposts that help to frame our understanding of the emergence of humans. The conventional timeline placed our species in Australia at no earlier than about 47,000 years ago, despite some archaeological and genomic research hinting at a much earlier arrival date. This video describes the important events in the timeline of human evolution As our ancestors’ intelligence increased, they developed the ability to make increasingly more complex stone, metal and other tools, create art and deliberately produce and sustain fire. These changes have resulted in dramatic increase in brain size and the reorganisation of the brain in which some parts, such as those involved in learning, have developed more than others, such as smell and vision.

This article is a discussion of the broad career of the human tribe from its probable beginnings millions of years ago in the Miocene Epoch (23 million to 5.3 million years ago [mya]) to the development of tool-based and symbolically structured modern human culture only tens of thousands of years ago, during the geologically recent Pleistocene Epoch (about 2.6 million to 11,700 years ago). Humans are classified in the sub-group of primates known as the Great Apes. The ancestors of today's modern apes (gorillas, orangutans, gibbons, chimpanzees and humans) first appeared in the fossil record about 27 million years ago. In devising such scenarios and filling in the human family bush, researchers must consult a large and diverse array of fossils, and they must also employ refined excavation methods and records, geochemical dating techniques, and data from other specialized fields such as genetics, ecology and paleoecology, and ethology (animal behaviour)—in short, all the tools of the multidisciplinary science of paleoanthropology. It is the subject of a broad scientific inquiry that seeks to understand and describe how this change and development occurred.

The nature of specific fossil specimens and species can be accurately described, as can the location where they were found and the period of time when they lived; but questions of how species lived and why they might have either died out or evolved into other species can only be addressed by formulating scenarios, albeit scientifically informed ones. However, the age of the oldest remains of the genus Homo is younger than this technological milestone, dating to some 2.8–2.75 million years ago in Ethiopia. These skulls are all casts of original fossils. Evidence of toolmaking dates to about 3.3 million years ago in Kenya. Max Planck Institute for Evolutionary Anthropology. Russell H. Tuttle is an active Professor of Anthropology, Evolutionary Biology, History of Science and Medicine and the College at the University of Chicago. This ancient primate has not been identified and may never be known with certainty, because fossil relationships are unclear even within the human lineage, which is more recent. Cranial capacity: the capacity or size of the brain case and therefore the brain. The primary resource for detailing the path of human evolution will always be fossil specimens.

Darwin never claimed, as some of his Victorian contemporaries insisted he had, that “man was descended from the apes,” and modern scientists would view such a statement as a useless simplification—just as they would dismiss any popular notions that a certain extinct species is the “missing link” between humans and the apes. | Xiujie Wu. Timeline of human evolution.
