![]() ![]() They might even be discovered this very year. In principle, fossilised remains of the LCA might come to light any time. And that puts the research community in a bit of a quandary. The trouble is that other researchers have equally well-reasoned models that suggest an LCA that looked and behaved in a completely different way. It is true that, today, some researchers have a well-thought-through idea of what the LCA looked like and how it behaved. There was once an animal that was an ancestor to both humans and apes. We have still not found the missing link between us and apes Modern humans later disperse into the Americas, most likely starting between 15,000 and 20,000 years ago. Modern humans arrive in Australia sometime between 45,000 and 60,000 years ago and into Europe between 30,000 and 40,000 years ago. Some early expansion out of Africa is seen at the Skhul and Qafzeh sites in Israel dating back 92,000 years ago, followed by later expansions into Eurasia by about 60,000 years ago. ![]() Evidence of an earlier appearance of modern humans in Africa includes remains from Omo in Ethiopia at 195,000 years ago, Herto in Ethiopia at 160,000 years ago, and the Klasies River Mouth in South Africa at 130,000 years ago. There has been growing consensus that the morphology characteristic of anatomically modern humans appears first in Africa with a subsequent dispersion into Eurasia. heidelbergensis and the Neandertals are sometimes referred to collectively as “archaic” humans to contrast with anatomically modern humans. Based on overall morphology, both specimens of H. sapiens or a separate species (Homo neanderthalensis). Debate continues over whether they should be referred to as a subspecies of H. Fossils known collectively as Neandertals are found in Europe and the Middle East, with some features appearing between 100,000 and 200,000 years ago in Europe and “classic” Neandertals dating back to about 70,000 years ago. By around 800,000 years ago or so, brain size increased more, and such specimens of Homo are often placed in the taxon Homo heidelbergensis, although others refer them to examples of early Homo sapiens. erectus dispersed out of Africa into Southeast Asia and the eastern edge of Europe. By 2 million years ago, the species Homo erectus emerged in Africa, with an increase in brain size, a reduction in the size of the face and teeth, and reliance on a stone tool technology. The earliest hominins, including species in the genera Ardipithecus and Australopithecus, lived in Africa and were bipeds with small brains and large faces. Fossil and genetic evidence suggests that the African ape and hominin lines diverged roughly 6–7 million years ago or so in Africa. In order to set the stage for understanding present-day patterns of variation, we need to review briefly the fossil record for hominin evolution (hominin is the term for humans and human ancestors back to the time of a divergence from the African ape line). That this two-million-year contemporaneousness has been largely camouflaged is a tribute to the skill of naturalist writers.Ĭontemporary genetic variation is understood best in light of our species’ past. This fact eliminates the possibility that Homo erectus evolved into Homo sapiens. Homo erectus individuals have lived side by side with other categories of true humans for the past two million years (according to evolutionist chronology). By every legitimate standard applicable, the fossil and cultural evidence indicates that Homo erectus is fully human and should be included in the Homo sapiens taxon. ![]() First, is Homo erectus morphologically distinct enough to warrant it's being classified as a species separate from Homo sapiens? The evidence clearly says no. Surprisingly, Homo erectus furnishes us with powerful evidence that falsifies the concept of human evolution. Thus Homo erectus is indispensable to the proponent of evolution as the transitional taxon. For the proponents of evolution, Homo erectus is the major category bridging the gap between the australopithecines (which most probably are nonhuman) and the early Homo sapiens and Neandertal fossils (which are truly human). ![]() It would be impossible to exaggerate the importance of this group of fossils, known collectively as Homo erectus.

Moreover, none of the three display any evolutionary trends during their tenure on earth.”(Gould 1976) africanus, the robust australopithecines, and H. “What has become of our ladder if there are three coexisting lineages of hominids (A.
