Ernst Haeckel, the famous German anatomist of the nineteenth century, argued that the orangutan is anatomically more similar to humans than are any of the nonhuman African apes. This led to
changing the species name for humans, temporarily, from Homo sapiens to Pithecanthropus sapiens.
the search for early human remains in the East African Rift Valley.
Charles Darwin’s inspiration to change his theory of human origins.
Eugene Dubois’s inspiration to search for the earliest human ancestors in Asia.
During the period 2.5–1.0 mya
several hominins, including but not limited to Homo erectus, Homo habilis, and various Australopithecine species, were alive at overlapping time periods, just as earlier periods saw several species of Australopithecine alive at once
the great diversity of hominins known from earlier periods was quickly trimmed down so only Homo erectus existed, alone, for most of that time.
there were two species of early hominin, Homo habilis living in Africa and Homo erectus living in Asia.
there was one widespread species of hominin, Homo erectus, with so much variation that early anthropologists thought there were several species existing side by side.
Homo erectus fossils date to
3–1 mya.
2.5–0.5 mya.
1.8 mya–300,000 yBP.
1.2 mya–800,000 yBP.
Dubois’s Pithecanthropus erectus finds consisted of
only skull fragments, so it was not known if Pithecanthropus erectus was bipedal.
only leg and other body fragments, so it was not known if Pithecanthropus erectus had a human-size brain.
a molar, a partial skull, and a femur, which indicated that Pithecanthropus erectus walked only partially upright, but had a human-size brain.
a molar, a partial skull, and a femur, which indicated that Pithecanthropus erectus walked much like a modern human but had a brain intermediate in size between a modern human and a typical nonhuman ape.
Homo erectus differed from earlier hominids in having traits such
a smaller brain.
larger teeth
a bigger sagittal keel.
a larger brain
What are the differences between Homo habilis and Homo
Homo habilis shows a reduction in the size of the face relative to the brain case.
Homo erectus shows a reduction in the size of the face relative to the brain case.
Homo habilis generally has a greater brain capacity than Homo erectus.
Homo erectus generally has a smaller brain capacity than Homo habilis.
Homo erectus’s cranial capacity
is always less than 1,000 cc.
is always more than 800 cc
ranges from 650 cc to 1,200 cc.
ranges from 900 cc to 1,200 cc.
Homo erectus’s high degree of adaptive success is evidenced by its
increased reliance on material culture
apparent increased intelligence.
reliance on unchanging environments.

often considered the same species and immediately ancestral to Homo sapiens.
often combined into one species, which is called Homo habilis.
