According to the evolution theory, what did humans evolve from? what is the name of the common ancestor...?

Question

between humans and apes? I read people saying that humans and apes share a common ancestor and apes are not our ancestors. So I want to know what is the name of this common ancestor and what did we eveolve from.

what did we evolve from? name the last species that existed before humans evolve of it.

Answer 1

"The oldest lineages of catarrhine primates, from which monkeys and apes evolved, are known between 50 and 33 million years ago. A primate known as Propliopithecus (one lineage sometimes called Aegyptopithecus), from the Fayum fossil sites of Egypt, is an archaic-looking catarrhine, and is thought to be what the common ancestor of all later Old World monkeys and apes looked like. So Propliopithecus may be considered an ancestor, or closely related to a direct ancestor, of humans. "

Humans are part of the hominid family. They are both part of and descended from them. The process of this development is called evolution. In brief, this means that new species develop and expand as they are better at dealing with their environment then others. See: http://www.nap.edu/readingroom/books/evolution98/front.html
for a discussion of the evolution process.

The hominids include humans and the apes. They are part of the family Hominidae, of the order Primate. Humans did not "descend from the apes" We share a common ancestor with them (Propliopithecus) and are considered "cousins." Chimpanzees, our closest relative, share a 99% match in DNA. In protein sequencing, the match is closer, no differences at all. When man's protein sequencing is compared to gorillas there is only two differences in the match with hemoglobin, red blood cells and amino acids. Lastly the antgen-antibody reaction for humans is 97% from chimpanzees compared to 50% for baboons. In other words we're related. DNA is today used to show how closely people are related (as in determining paternity) and to determine if people were at a crime scene (as a means to determine guilt or innocence). It also is used to determine how long ago species split off from each other.

The split from the apes is put at 8 million years ago. That's based both on the fossil remains and the know rate of change for DNA. The first bipedal hominids (walking on two feet) is 4 million years ago. The first known bipedal hominids were the Australopithecus. ("Southern Ape") There are several known types and the exact lineage is still being argued. The known family tree is:

Australopithecus afarenis "Southern Ape of Afar" This is the species "Lucy" belongs to. Brain size is about 410cc, they stood between 3 and 4 feet and weighed about 65 pounds. They went extinct about 2.5 million years ago.

Australopithecus africanus "Southern Ape of Africa" Probably evolved from Australopithecus afarenis and lived 3 to 1 million years ago. Brain size was about the same as a gorilla's and they stood between 3 and 4 feet tall. Weight was about 45 to 90 pounds.

Australopithecus robustis "Robust Southern Ape" This species is larger then Australopithecus africanus , 4 feet 11 inches and 5 feet 7 inches, and weighed 110-154 pounds. Brain size is put at 500cc. This group lived 2.5 million to 1.5 million years ago. There is argument that robustis was the male of the afarenis or africanus species.

Australopithecus boisei "Bosie Southern Ape" boisei is named after one Charles Boise and supporter of fossil hunts. The original name was Zinjanthropus "East Africa man" The species lived 2.5 to 1 million years ago. Height was between 5 feet 3 inches to 5 feet 10 inches. Weight was between 132 and 176 pounds. Brain size was about 500cc. boisei is nicknamed "Nutcracker man" due to its large jaw and massive grinding teeth. However, examination has shown that it could chew no harder then us and it's diet seems to have primarily been of leaves.

Homo habilis "Handy man" This is reported to be the first known species of the genus Homo. The brain is larger the Australopithecus, 650-800cc compared to 500cc, the arms shorter, and hip bones that facilitated bipedal walking. Body size was reduced from boisei and robustis, back to between four and five feet. Weight is put at 110 pounds. The species is dated at 2.5 to 1.5 million years ago. Habilis was a throw back in that the head had not changed with the rest of the body. It still retained the brow ridges, jaws and nose of the Australopithecus. In fact, some discoveries were so labeled.

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.

Answer 2

i believe it's not known. in fact, i think scientists are still trying to pinpoint when the last chimp-human split was. if you think, it's hard to know what the common ancestor would be. if you find a fossil and say it comes at or before the split, you would not really know if there is one more species between that one and the split. or if your fossil was similar to the common ancestor, but not quite it.

if they can get DNA from a preserved animal (i.e. not a fossil) it would be easier. that's rare though.

Answer 3

first we are very much like the ape. We are more like the chimpanzee only one chromosome separates the two. You say apes are not related to us. we are both primates. Man did evolve, but he jump from one form to modern man in world record time. There is a missing link to the evolutionare chain. This event should had taken millions of years, but we did it in no time flat. This is where we as humans left are breatherns the apes in the dust.

Answer 4

It is an ape-like creature that has not yet been identified, so has no name. Hence, the THEORY of evolution.

This is where the term "Missing Link" comes into evolution. There's a clear chain of evolution up to a certain point, and then there is just something missing, there's a creature needed to connect us to the rest of the chain that is also clear. It will happen some day, but fossil records are difficult to come by that old, so it'll take time.

Answer 5

Possibly bats

Answer 6

god made man from the dust of the earth but according to evolution i think we are supposed to come from the sea from plankton

Answer 7

what is the name of the common ancestor...?----Murray

Answer 8

We evolved from Adam and Eve.

Answer 9

I think it was a Neanderthal, it its no that then i don't know.
