Homo sapiens vs. homo erectus:?

Question

what is the differences between homo sapiens and homo erectus?

Answer 1

They're the same.

Answer 2

From the neck down, they're virtually identical!

The skull shapes are slightly different which some evolutionary biologists have suggested that Homo erectus may have lasted until about 27,000 BP, in Asia, and contributed somewhat to the slightly different appearance of modern Mongoloid (East Asian/Oriental) Homo sapiens populations!

Homo erectus "Upright Man") was the first hominid to leave Africa. His existence dates from 1.6 million years ago to perhaps 200,000 years ago. However, recent discovers have suggested that isolated populations may have existed even later.

Brain size is put at 850cc, height up to 6 feet and weight was comparable to modern humans.

Early discoveries of Homo Eretus remains were variously named Peking Man, Java Man and Heidelberg Man. His range was all of Africa, most of Europe and as far east as China. Sites in California have been suggested as containing Homo erectus finds. No one had satisfactorily explained how the vast distance from China to California was crossed. Recently a small sample the population of China was tested to determine their DNA. The theory tested was that man developed in Africa, spread out and then further developed in China. What was found suggested that waves of hominids came out of Africa, each developed the race further. The idea how having man develop in several regions and not just Africa has supporters as does the "out of Africa" theory.

Homo sapiens neanderthalenis "Man from the Neander Valley" This species is today considered a "dead end," someone that did not give rise to Homo sapiens sapiens. The latest support has come from DNA analysis of his bones. They don't match with Homo sapiens sapiens. In other words, humans did not develop fro the Neandertals. Neandertals are larger in body then modern humans with massive bones. They have short, compact bodies, with large joints and hands. The body shape suggests they were well adapted to cold environments. They are dated between 200,000 to 30,000 years ago. In some sites (the Middle East at Jebel Irhoud, Tabun, and Skhul) the two species (Homo sapiens, and Homo sapiens neanderthalenis) lived near each other. It has been suggested that an archaic Homo sapiens gave rise to the species. They had to date been found only in Europe and the Middle East. It has been suggested that while the species was successful, they may have a a lower birth rate then the early humans. Given only a 2% lower rate per generation would lead to extenuation.

Homo sapiens "Man who thinks" The archaic form is dated between 500,000 and 150,000 years ago. Brain size is about 1200cc. The species shows strong links and the characteristic of Homo erectus.

Homo sapiens sapiens Modern man. The first know group appears some 40,000 years ago during the Neolithic period. However, new finds are pushing that date back. This is where Cro-Magnum is placed

Answer 4

Humans, or human beings, are bipedal primates belonging to the mammalian species Homo sapiens in the family Hominidae (the great apes). Compared to other living organisms on Earth, humans have a highly developed brain capable of abstract reasoning, language, and introspection. This mental capability, combined with an erect body carriage that frees their upper limbs for manipulating objects, has allowed humans to make far greater use of tools than any other species. DNA evidence indicates that modern humans originated in Africa about 200,000 years ago, and they now inhabit almost every continent, with a total population of over 6.6 billion as of 2007.

Homo erectus (Latin: "upright man") is an extinct species of the genus Homo. Dutch anatomist Eugene Dubois (1890s) first described it as Pithecanthropus erectus, based on a calotte (skullcap) and a modern-looking femur found from the bank of the Solo River at Trinil, in central Java. However, thanks to Canadian anatomist Davidson Black's (1921) initial description of a lower molar, which was dubbed Sinanthropus pekinensis, most of the early and spectacular discoveries of this taxon took place at Zhoukoudian in China. German anatomist Franz Weidenreich provided much of the detailed description of this material in several monographs published in the journal Palaeontologica Sinica (Series D). However, nearly all of the original specimens were lost during World War II. High quality Weidenreichian casts do exist and are considered to be reliable evidence; these are curated at the American Museum of Natural History (NYC) and at the Institute of Vertebrate Paleontology and Paleoanthropology (Beijing).

Throughout much of the 20th century, anthropologists debated the role of H. erectus in human evolution. Early in the century, due to discoveries on Java and at Zhoukoudian, it was believed that modern humans first evolved in Asia. This contradicted Charles Darwin's idea of African human origin. However, during the 1950s and 1970s, numerous fossil finds from East Africa (Kenya) yielded evidence that the oldest hominins originated there. It is now believed that H. erectus is a descendant of earlier hominins such as Australopithecus and early Homo species (e.g., H. habilis), although new findings in 2007 suggest that H. habilis and H. erectus coexisted and may be separate lineages from a common ancestor.

H. erectus originally migrated from Africa during the Early Pleistocene, possibly as a result of the operation of the Saharan pump, around 2.0 million years ago, and dispersed throughout most of the Old World, reaching as far as Southeast Asia.

Fossilized remains 1.8 and 1.0 million years old have been found in Africa Europe (Georgia, Spain), Indonesia (e.g., Sangiran and Trinil), Vietnam, and China. H. erectus is an important hominin because it is believed to have been the first to leave Africa. However, some scholars believe that H. erectus is not the direct ancestor of modern H. sapiens.

A homo erectus skull, Tchadanthropus uxoris, discovered in 1961, is the partial skull of the first early hominid till then discovered in Central Africa, found in Chad during an expedition led by the anthropologist Yves Coppens. While some then thought it was a variety of the Homo habilis, the Tchadanthropus uxoris is no longer considered to be a separate species, and scholars consider it to be Homo erectus, and it is even argued that the skull is just a modern human, Homo sapiens sapiens, weathered by the elements to look like an australopithecine skull.

Geez, nitwit.
