Homo erectus (Dubois, 1892)
To understand what we mean today by "Homo erectus", some history of paleoanthropological thought is needed. The first early human fossil found outside of Europe.
The fossil was placed in the species Pithecanthropus erectus by its discoverer Eugene Dubois.
Almost 40 individuals have been recovered from Java to this day, roughly equivalent to the number of fossils found at the caves of Choukoutien in China.
The Choukoutien fossils found were originally assigned the species name Sinanthropus pekinensis.
It was not until the 1950's that Ernst Mayr proposed that all of the specimens from these two roughly contemporaneous locales, along with others localities from Europe and Africa, represented a single species, Homo erectus.
Since the 1950's, however, the early African populations of what Mayr termed Homo erectus have once again been split into a separate species Homo ergaster.
Homo erectus exhibits many features particular to the species, including a long skull shaped with thick cranial walls. The back of the skull is marked with a protruberance known as a transverse torus.
Over the eyes is a large and prominent browridge, or supraorbital torus, which joins the rest of the frontal bone at a depression called the sulcus.
Cranial capacities of Homo erectus average around 1000cc, which is far greater than earlier australopiths and even early Homo.
The dentition of Homo erectus is nearly identical to modern humans, although the cheek teeth do remain larger, and the mandible is generally more robust.
The species Homo erectus is thought to have diverged from Homo ergaster populations roughly 1.6 million years ago, and then spread into Asia.
It was believed that Homo erectus disappeared as other populations of archaic Homo evolved roughly 400,000 years ago.
Evidently, this is not the case. Recent studies into the complicated stratigraphy of the Java Homo erectus sites have revealed some surprising information.
Researchers have dated the deposits thought to contain the fossils of H. erectus near the Solo River in Java to only 50,000 years ago. This would mean that at least one population of Homo erectus in Java was a contemporary of modern humans (Homo sapiens).REP. GUINEA CONAKRY

Finally, we raise to the rank of a separate family the whole complex of Helladopithecus finds from Greece, classifying it right after the Hominid family.
As a result of the above process we have the first standing man on earth, Homo erectus trilliensis, spreading all over the world from this region of the Aegean, of the SE of Europe 13 million years ago.
The find was named Homo erectus trilliensis Daphnae, after the name of the lady present in this hall Mrs Daphnae A.Poulianos.

Homo ergaster - (from the Greek ἔργον, "work") is an extinct species (or subspecies) of hominid that lived in eastern and southern Africa from the end of the Pliocene epoch to the early Pleistocene, about 1.8-1.3 million years ago.
There is still disagreement on the subject of the classification, ancestry, and progeny of H. ergaster, but it is now widely thought (though not agreed) to be the direct ancestor of later hominids such as Homo heidelbergensis, Homo sapiens and Homo neanderthalensis rather than Asian erectus.
It is one of the earliest members of the genus Homo, possibly descended from, or sharing a common ancestor with, Homo habilis.

One of the first inhabitants of Southern Italy, the Homo Aeserniensis, lived about seven hundred thousand years ago, by hunting and fishing. Close by a small watercourse he had built huts using elephant tusks and the flat bones of rhinoceroses, boars, bison and other wild beasts.

The evolutionary dividing line between Homo erectus and modern humans was not sharp.
It extended over several hundred thousand years during the middle of the Pleistocene Epoch.
Adding to the confusion about this important transitional period is the fact that some regions were ahead of others in the process of evolving into our species.
The evolutionary changes above the neck that would lead to modern humans may have begun in Southern Europe and East Africa 800,000-700,000 years ago.
The oldest flossies date of have a million and six hundred thousand years found in Eastern Turkana in the Kenya, being for Just-fond times related as pertaining to the a Turkana. A million of years later the Homo erectus and its sister, the Homo heidelbergensis, occupy all the Eurasia, since the coast of the Atlantic Ocean, Occident, until the a China and Java, the east.
