Question

Can you describe in detail the environmental situation and cultural inventions and capabilities concerning Homo erectus leaving Africa?

Answer 1

Homo erectus :

Upright man :

Homo erectus is an extinct species of archaic human from the Pleistocene, earliest occurrence about 2 mya, and is one of the first recognisable members of the genus Homo.

Those dates mark the end of a long run. Homo erectus was the first known human species to evolve modern body proportions—including shorter arms and longer legs that indicate an upright walking lifestyle that permanently traded the trees for the ground. The close relative to Homo sapiens was also the first hominin known to leave Africa, and Homo erectus spread more widely than any other human species except our own.

The geological work suggests that the dozen Homo erectus individuals died upriver and were washed downstream by monsoon flooding, then were caught in debris jams where the ancient river narrowed at Ngandong. At that spot, they were further buried by channels of flowing mud.

At least their skulls were. The research team also offers an explanation for why the rest of the Homo erectus skeletons went missing

There are a number of fascinating evolutionary questions that can be asked of H. erectus. The species was not only geographically widespread, it also had a long temporal span in the hominin fossil record (Antón 2003). With its earliest appearance in the fossil record from localities in the Lake Turkana Basin, Kenya, sometime around two million years ago, H. erectus populations persisted until near the end of the Pleistocene, as evidenced by fossils from Southeast Asia. Homo erectus thus presents paleoanthropologists with the challenge of trying to interpret fossil variation in the context of both widespread geographic and temporal distribution.

What is the evolutionary relationship among fossils that share many similarities, but also subtle differences, separated across time and space

Features:

Increased body size

Increased brain size that is encephalization

Reduced post canine dentition size

Increase in technological intensification

Homo erectus inventions

Homo Erectus Tools. Homo erectus was the first to use fire and sophisticated tools. Unlike earlier hominins that developed crude choppers and flakes, Homo erectus produced sophisticated stone axes and used sharp stone cleavers and finger-size scrapers used slice off chewable sizes of meat.

Capabilities and skills

They were able to walk and run long distances. They could control fire and cook food. They created more tools & weapons for butchering and hunting, such as stone axes and knives. But it is considered that their hands weren't as well adapted for tool making.

Special about them are  The extinct ancient human Homo erectus is a species of firsts. It was the first of our relatives to have human-like body proportions, with shorter arms and longer legs relative to its torso. It was also the first known hominin to migrate out of Africa, and possibly the first to cook food.
