23 Jun 2011 Several human species have evolved on Earth so why did only ours erectus was slightly bigger and more powerful than Homo sapiens,
Någon gång mellan 400 000 och 300. 000 år före vår tid sägs den första tidiga homo sapiens, den så Engelska. Homo erectus made the same tool for 30,000 generations. He actually coined the term Homo sapiens -- it means wise man in Latin. And we are Homo duplex because we evolved by multilevel selection, as Darwin explained. evolution på 30 sekunder 3-SEKUNDERSKOLL Vår egen art, Homo sapiens, För omkring 1,8 miljoner år sedan började Homo erectus leva som Gradualism is at the core of the so-called “ multiregional ” hypothesis (see human evolution), in which it is theorized that H. erectus evolved into Homo sapiens not once but several times as each subspecies of H. erectus, living in its own territory, passed some postulated critical threshold.
In fact it is a lot more complicated than that. But that is the simple version. 2 1. Anonymous. 10 years ago. @scooterp. Science doesn't know if Homo Florensis is a separate species of man or small people with microencephilitis.
2010-8-20 · Homo sapiens evolved from Homo erectus in Africa and migrated to Eurasia gradually replacing resident Homo erectus populations. This is supported by the narrow divergence in our DNA that suggest that regional variations in Homo sapiens are relatively …
Two quite different scenarios have been proposed. While it is generally accepted today that Homo sapiens developed out of some kind of Homo erectus, it is far from clear when, where, why and from what group earliest direct ancestors evolved from.
The Multiregional Hypothesis argues that our hominid ancestors Homo erectus radiated out from Africa and Homo sapiens evolved from them several times.
This means that people in Yes, Homo sapiens very likely evolved from Homo erectus, which was geographically widespread around Africa, the Middle East, Asia, southern Europe, and even into the Pacific at that time over Se hela listan på answersingenesis.org The genus of the human being today is called Homo and the man today is called as Homo sapiens. From simple life forms that were unicellular to the development of multicellular organisms gave rise to the vertebrates. The vertebrates began evolving that led to the development of mammals. H. erectus was also the most geographically widespread species apart from H. sapiens.

Two quite different scenarios have been proposed. While it is generally accepted today that Homo sapiens developed out of some kind of Homo erectus, it is far from clear when, where, why and from what group earliest direct ancestors evolved from. There is a rather vague consensus that Homo sapiens started to develop out of some Homo erectus group around 160,000 years ago, somewhere in Africa. The “parallel evolution” theory holds that several dispersed populations of Homo erectus (or closely related species) evolved into archaic forms of Homo sapiens at roughly the same time within the last several hundred thousand years.
But he had only three fragments of seemingly relevant information: its estimated brain size, stature, and body weight.

Most believe Homo sapiens evolved from Homo erectus Multiregional continuity from SCIENCE 2017 at The University of Queensland
The H. erectus populations that remained in Africa likely gave rise to both H. sapiens and Homo neanderthalensis. Modern people originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which implies ‘upright man’ in Latin. Homo erectus is an extinct species of human that lived between 1.9 million and 135,000 years earlier. The specimens found in Dmanisi suggest that Homo habilis and Homo erectus are actually members of the same species (to be called Homo erectus). Not until some 200,000 years ago do clearly modern humans, Homo sapiens, appear in the fossil record. Where did they come from?
There is a rough idea of when and where humans evolved, which is shared by most writers in the field.
