Compared to Neanderthals, modern humans have a better sense of smell Differences in the temporal lobes and olfactory bulbs also suggest a combined use of brain functions related to cognition and olfaction. The increase of brain size is intimately linked to the evolution of humanity. Two different human species, Neanderthals and modern humans, have independently evolved brains of roughly the same size but with differing shapes. This could indicate a difference in the underlying brain...

Dietary change led to the appearance of modern humans in the Middle East 400,000 years ago, say TAU researchers Elephants have long been known to be part of the Homo erectus diet. But the significance of this specific food source, in relation to both the survival of Homo erectus and the evolution of modern humans, has never been understood – until now. When Tel Aviv University researchers Dr. Ran Barkai, Miki Ben-Dor, and Prof. Avi Gopher of TAU's Department of Archaeology and...

A series of new archaeological discoveries in the Sultanate of Oman, nestled in the southeastern corner of the Arabian Peninsula, reveals the timing and identity of one of the first modern human groups to migrate out of Africa, according to a research article published in the open-access journal PLoS ONE. An international team of archaeologists and geologists working in the Dhofar Mountains of southern Oman, led by Dr. Jeffrey Rose of the University of Birmingham, report finding over 100...

Ice Age Hominins And Their Adaptability To Climate Change
2011-11-17 10:07:33

Complex computational modeling provides clues to Neanderthal extinction Computational modeling that examines evidence of how hominin groups evolved culturally and biologically in response to climate change during the last Ice Age also bears new insights into the extinction of Neanderthals. Details of the complex modeling experiments conducted at Arizona State University and the University of Colorado Denver will be published in the December issue of the journal Human Ecology, available...

'First Wave' Settlers Had Key Role In Human Evolution
2011-11-04 05:38:01

A new study examining the genealogies of early human pioneers suggests that settlers who were first to colonize a new region of the world produced more offspring than the settlers who followed them, giving them a selective advantage. The international team of researchers, who specialize in studying the effects of rapid territorial and demographic expansions on recent human evolution, analyzed the growth of human colonies in an area of Quebec, Canada, between 1686 and 1960.  They...

By taking a second look at seemingly insignificant fossils, two international teams of researchers have discovered that modern humans arrived in Europe earlier than scientists had originally believed, various media outlets reported on Wednesday. According to AP Science Writer Alicia Chang, the fossils at the center of the discovery were a piece of jawbone with three teeth from England, and a pair of infant teeth from the southern part of Italy. Using what Chang refers to as "refined...

Humans Share Genes With Earlier Human Species

Humans not only mated with the ancient Neanderthals, but according to a new study from Uppsala University researchers, the East Asian population of the modern species may have also mated with a hominin species known as Denisovans that lived in Siberia 40,000 years ago. Denisovans are only known from a few bone fragments, including a finger bone, a tooth and a possible toe bone, which is still undergoing analysis. Denisovans likely split from the Neanderthal tree around 300,000 years ago,...

[ Watch the Video ] Archaeologists have uncovered two shells near the southern coast of South Africa that contain a primitive paint mixture, revealing what experts believe may be the remnants of the world´s earliest art studio. The 100,000-year-old workshop was likely used to mix and store the reddish pigment ochre, and was unearthed in Blombos Cave near Cape Town.  The scientists had previously found some of the earliest sharp stone tools at this same site, along with...

An international team of scientists, including researchers from Murdoch University, have just published findings that re-interpret the history of our species' original dispersals across the planet. Using a piece of hair donated by a West Australian Aboriginal man around 100 years ago, the team sequenced an individual's entire DNA code (or genome) to prove that multiple dispersals of early humans populated the world, contrary to the commonly-held single dispersal theory. Perth, Western...

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,...
