The nature of homo erectus a hominid species

Homo erectus Homo erectus Where Lived: These features are considered adaptations to a life lived on the ground, indicating the loss of earlier tree-climbing adaptations, with the ability to walk and possibly run long distances. Compared with earlier fossil humans, note the expanded braincase relative to the size of the face. Microscopic study of the teeth indicates that he grew up at a growth rate similar to that of a great ape.

There is fossil evidence that this species cared for old and weak individuals. The appearance of Homo erectus in the fossil record is often associated with the earliest handaxes, the first major innovation in stone tool technology.

Ranges from 4 ft 9 in - 6 ft 1 the nature of homo erectus a hominid species 145 - 185 cm Weight: Paleoanthropologists are constantly in the field, excavating new areas, using groundbreaking technology, and continually filling in some of the gaps about our understanding of human evolution.

Homo Erectus: Facts About the

Below are some of the still unanswered questions about Homo erectus the nature of homo erectus a hominid species may be answered with future discoveries: Was Homo erectus the direct ancestor of Homo sapiens, our own species? Data suggest that increasing body size, greater reliance on animal food resources, and increased range size were part of a web of factors that facilitated the initial early dispersal of H.

Was one of these factors more important than the others? Are the fossils from earlier time periods in East Africa, and from Georgia, all part of a single species Homo erectusregionally variable in size and shape? Or are there actually several species of the nature of homo erectus a hominid species human represented by what we are now calling Homo erectus?

Did Homo erectus grow up in a more human-like pattern and rate, or a more ape-like one? Was Homo erectus the first early human species to experience an adolescent growth spurt? Natural history of Homo erectus. Yearbook of Physical Anthropology 46, 126—170.

The tall bodies and large brains the nature of homo erectus a hominid species Homo erectus individuals required a lot of energy on a regular basis to function. Eating meat and other types of protein that could be quickly digested made it possible to absorb nutrients with a shorter digestive tract, making more energy available faster. There is also speculation that honey and underground tubers may have been significant food sources for Homo erectus.

Known as the Acheulean stone tool industry, it consisted of the creation of large cutting the nature of homo erectus a hominid species like handaxes and cleavers. Increased reliance on a broader set of tools may have helped Homo erectus survive during changing climates. In either case, there is general agreement that it descended from an earlier species of Homo e. At the beginning of its time range, around 1. Sometimes they were even found at the same fossil sites.

D3444 This elderly male belonged to a population of Homo erectus that spread from Africa to the Caucasus Mountains in western Asia. Most of his teeth fell out long before he died, and his jaw deteriorated as a result. Members of his social group must have taken care of him. His teeth indicate that he grew up quickly, at a rate similar to that of a living great ape.

His is one of the most complete early human skeletons ever found.
