Research at the University of Liverpool has found that periods of rapid fluctuation in temperature coincided with the emergence of the first distant relatives of human beings and the appearance and spread of stone tools. Dr Matt Grove from the School of Archaeology, Classics and Egyptology reconstructed likely responses of human ancestors to the climate of the past five million years using genetic modeling techniques. When results were mapped against the timeline of human evolution, Dr...

Researchers at Brown University and Stanford University have pieced together ancient human migration in North and South America. Writing in the American Journal of Physical Anthropology, the authors find that technology spread more slowly in the Americas than in Eurasia. Population groups in the Americas have less frequent exchanges than groups that fanned out over  Europe and Asia. How modern-day humans dispersed on the planet and the pace of civilization-changing technologies that...

Humans Didn’t Often Mate With Neanderthals

  Modern humans do show some traces of DNA from Neanderthals, but a new study from Swiss researchers suggests that any breeding between the two was a relatively rare event. The new model, based on DNA samples from modern humans in France and China, shows that successful breeding between the two species occurred at a rate of less than 2 percent, according to researchers at the University of Geneva and the University of Berne in Switzerland. The research, published Monday in the...

Image 1 - New Evolutionary Link Between Australopiths And Humans

  [ View Video] New analysis of two-million-year-old hominid bones found in South Africa provide the clearest evidence of evolution´s first major step toward modern humans, evidence that is leading some experts to believe the findings will change longstanding views on the origins of humans. The well-preserved bones, from Australopithecus sediba, are from a part-human, part-ape species that have never been seen before now. The hands are similar to man, it has sophisticated...

Evolution's Past Is Modern Human's Present

  Mandenka, Biaka and San tested for DNA evidence of ancient interbreeding inside Africa The past is present when it comes to human evolution. That seems to be the takeaway from new research that concludes "archaic" humans, somewhere in Africa during the last 20-60 thousand years, interbred with anatomically modern humans and transferred small amounts of genetic material to their offspring who are alive today. University of Arizona geneticist Michael Hammer and a team of...

Ancient Humans Interbred With Other Hominin Species
2011-09-06 05:10:50

  A new study finds that our ancestors bred with more archaic hominin forms around 35,000 years ago, before they migrated out of Africa. In fact, up to 2% of the genomes of some modern African populations may originally have come from a closely related species, the researchers said. It is widely accepted that the species Homo sapiens originated in Africa, and eventually spread throughout the world.  However, paleontologists have long wondered whether modern humans came from...

Stone Tools Give New Insights On Early Human Migrations
2011-09-01 05:23:19

  Ancient humans made cleavers, hand axes and other advanced stone tools 300,000 years earlier than previously believed, but did not take these tools with them when they left Africa, according to a new study published this week in the journal Nature. Researchers from the United States and France traveled in 2007 to an archaeological site along the northwest shoreline of Lake Turkana in Kenya, where primitive stone flakes, two-faced blades and other large carving tools had been...

  Sexual encounters with Neanderthals produced offspring who inherited vital genes that have helped modern humans combat illness and disease, according to a study published Thursday in the journal Science. The scientists extracted material from the leg of a Neanderthal and the fingerbone of a Denisovan, an apparent sister species, which yielded readable DNA.  An analysis of the DNA revealed that most of us have some of the genes of these ancient humans. Indeed, the...

A Stanford University scientist is claiming that interbreeding between human ancestors and Neanderthals that took place between 65,000 and 90,000 years ago may have helped our kind survive and gain evolutionary dominance. According to Peter Parham, an immunology expert at the California university's medical school, crossbreeding between the two species "provided humans with a ready-mixed cocktail of disease-resistant genes when the species first ventured out of its native Africa," Graeme...

The 300,000 year reign of the Neanderthals most likely came to an end because of simple numbers, as modern humans outnumbered their predecessors by a 10-to-1 margin, researchers from Cambridge University claim in a new study. Once the hoards of homo sapiens poured into Western Europe, they overwhelmed Neanderthals, effectively making them "a minority in their own land," Guardian Science Correspondent Ian Sample wrote on Thursday. The sheer numbers of these new residents quickly ended the...

Neanderthals
2013-10-03 16:03:35

The Neanderthals or Neandertals are an extinct species or subspecies of the genus Homo which is closely related to modern humans. They are known from fossils, dating back from the Pleistocene period, which have been found in Europe and parts of western and central Asia. The species gets its name from Neandertal, “Neander’s Valley”, the location in Germany where it was first uncovered. Neanderthals are classified either as a subspecies of Homo sapiens or as a distinct species of the...

Homo sapiens
2013-09-24 13:55:52

Homo sapiens is the scientific name for the human species. Homo is the human genus, which also includes Neanderthals and various other extinct species of hominid. H. sapiens is the only surviving species of the genus Homo. Modern humans are the subspecies Homo sapiens sapiens, distinguished from their direct ancestor, Homo sapiens idaltu (http://en.wikipedia.org/wiki/Homo_sapiens_idaltu). Subspecies of H. sapiens include Homo sapiens idaltu, roughly translated as “elder wise human” and...

Homo sapiens idaltu
2013-09-24 12:20:45

Homo sapiens idaltu is an extinct subspecies of Homo sapiens that lived nearly 160,000 years ago during the Pleistocene in Africa. “Idaltu” comes from the Saho-Afar word meaning “elder” or “first born”. The fossilized remains of H. s. idaltu were uncovered at Herto Bouri near the Middle Awash site of Ethiopia’s Afar Triangle in the year 1997 by Tim White, but were first revealed in 2003. Herto Bouri is a portion of Ethiopia under volcanic layers. By using radioisotope dating,...
