Homo erectus 8

Homo erectus


Early African Homo erectus fossils are the oldest known early humans to have possessed modern human-like body proportions with relatively elongated legs and shorter arms compared to the size of the torso. 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.

When and where did they live?


Some relevant fossils

How tall and heavy were they?

Eugene DuBois, a Dutch surgeon, found the first Homo erectus individual in Indonesia in 1891. In 1894, DuBois named the species Pithecanthropus erectus, or ‘erect ape-man.’ At that time, Pithecanthropus (later changed to Homo) erectus was the most primitive and smallest-brained of all known early human species; no early human fossils had even been discovered in Africa yet.

Homo erectus got its name because it was the first species to walk completely upright without stopping.

They lived in Northern, Eastern, and Southern Africa; Western Asia and East Asia, between about 1.89 million and 143,000 years ago.

The first fossils attributed to Homo erectus were founded on the island of Java in 1891. DuBois found his first specimen, an angled red skull.

How they lived

The tall bodies and large brains of Homo erectus individuals required a lot of energy 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. Honey and underground tubers may have been significant food sources for Homo erectus.

They created large cutting tools that may have helped Homo erectus survive during changing climates.Campfires occur during the time range of Homo erectus. They were used for cooking and sharing food; they were places for social interaction, and also used for warmth and to keep away large predators.
