yes
Homo erectus and Homo ergaster are two distinct species within the Homo genus. Homo ergaster is considered to be an African species that eventually evolved into Homo erectus, which was more widespread and inhabited both Africa and parts of Asia. Homo ergaster is generally seen as a transitional species between Homo habilis and Homo erectus.
The oldest examples of Homo Sapiens is from the Omo remains, presumably dating back to 195,000 in Ethiopia. It was another 60,000 years until Homo Sapiens remains become prolific and visible in other parts of the world. This supports the "out of Africa" theory that Homo Sapiens, like many of the other hominid species evolved in Africa and spread out from there. Homo Erectus is mostly found in other parts of the world. There is no clear consensus within the Palaeoanthropology community whether Homo Erectus is a direct link to Homo Sapiens or whether Homo Sapiens came from within a different line that existed at the same time in Africa. There were many different hominid species that existed during this time frame, and indications are that it may be the most diverse period of hominid specie existence in the earth's history. To date, Homo Sapiens is the only known hominid with a high forehead, flat face, and thin, flat brows. It resembles much more closely Homo Heidelbergensis than Homo Erectus.
No, H. sapiens arose out of local populations of H. erectus in Africa, Asia and Europe. Although, there is the single origin hypothesis theory that modern humans (H. Sapiens) arose out of a single population of late H. erectus in Africa around 150,000 years ago.
We can't know that for sure because we don't have a sample of Homo Erectus' DNA. We only have fossils which are just rock in the shape of bones. So basically the answer is that no one knows for sure the exact number
Homo erectus is believed to be the first hominin to have mastered fire, approximately 1.5 million years ago. They were able to control fire for cooking and warmth. Homo habilis, an earlier species, is not known to have used fire in the same way.
Groups that lived at the same time as Homo sapiens include Neanderthals, Denisovans, and Homo erectus. These groups were early human relatives that coexisted with Homo sapiens during different periods of prehistory.
Christian religion holds in term that the Bible mentioned this species that had gone extinct, lived once with humans. A pretified foot print has been discovered along a pretified human foot print. The same goes for the homo erectus.
Evidence suggests that Homo erectus likely did not create art in the same way that later Homo sapiens did. While they did use tools and may have created simple symbols or markings, there is little indication of complex artistic expression such as cave paintings or sculptures.
Homo sapiens is a largely biological designation and science does not allow issues of spirit to tread upon it. But the world is changing quickly. Issues of the spirit are on the rise and the next stage of human evolution already has some names floating around: homo spiritus homo sanctus It's a change in which either science, or common perception dictates that we do have spirits, and are divine, destined for immortality. http://www.paep.ca/en/CIYL/2002/doc/peck_homo_sapiens.pdf
The Homo Eretus(Upright Man in latin) were the first homind to migrate and the first to care for each other. Also the first to create fire and hunt
Homo sapiens and Homo erectus
Bones of homo erectus in these areas have been discovered.There are actually two theories of the origin of homo erectus:they originated in Africa and migrated to Eurasiathey originated in Eurasia and migrated to AfricaBones have been discovered in the Caucasus region and are believed to have been either around the same time or even earlier than those that have been found in Africa.
