History Incipient Beginning With Uncivilized First Primate-Hominid Species.

a)      What changes in the body of primates had to occur for hominids to walk upright?

What was the first hominid to walk upright?

Homo erectus, or the first humans to walk upright, lived longer than we previously thought, according to new research.Dec 19, 2019

b)    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.

History and Geography

Eugene Dubois first identified and described a new human-like set of Indonesian fossils at the end of the 19th century, naming the specimens Pithecanthropus erectus (upright, ape-man) because of their combination of bipedality and a brain size much smaller than living humans. Dubois had specifically been looking for the missing link between apes and humans, and for him the combination of a human-like body and ape-like brain represented just that (Shipman 2002). Subsequent discoveries in the 1920s and 1930s from the site of Zhoukoudian, China, of fossils with similar characteristics-originally designated Sinanthropus pekinensis-raised the question of a possible evolutionary relationship between these regional samples. Today, these two samples, along with a much larger collection of fossils from Asia, Africa, and Europe, are most commonly referred to simply as Homo erectus.
