What are common methods of differentiating between early hominid stages of human evolution?

Question

-height of the fossil remains

-size of pelvic bones

-geographic location of the fossil remains

-written records left by the early hominid stages

-the complexity of the tools used by the individual stages

Answer 1

Forget written records. early hominids had no written languages.

Height

dentition

pelvic bones can help identify whether or not the creature walked upright.

Skull (brain case) capacity (how big was their brain?) 750 to1300 cc.

geographic location may be important in identifying whether or not a fossil is related to other known fossils.

complexity of tools is also a factor in identifying the division of labor and social structure.

Answer 2

The skull and the ribcage are the most defining elements!

Tools, geologic layers, and location support the evidence collected.
