What Makes Humans And Chimps Different?
2011-10-26 03:00:27

For years, scientists believed the vast phenotypic differences between humans and chimpanzees would be easily explained — the two species must have significantly different genetic makeups. However, when their genomes were later sequenced, researchers were surprised to learn that the DNA sequences of human and chimpanzee genes are nearly identical. What then is responsible for the many morphological and behavioral differences between the two species? Researchers at the Georgia Institute...

Culture is not a trait that is unique to humans. By studying orangutan populations, a team of researchers headed by anthropologist Michael Krützen from the University of Zurich has demonstrated that great apes also have the ability to learn socially and pass them down through a great many generations. The researchers provide the first evidence that culture in humans and great apes has the same evolutionary roots, thus answering the contentious question as to whether variation...

New Technologies Challenge Old Ideas About Early Hominid Diets
2011-10-14 07:11:32

New assessments by researchers using the latest high-tech tools to study the diets of early hominids are challenging long-held assumptions about what our ancestors ate, says a study by the University of Colorado Boulder and the University of Arkansas. By analyzing microscopic pits and scratches on hominid teeth, as well as stable isotopes of carbon found in teeth, researchers are getting a very different picture of the diet habitats of early hominids than that painted by the physical...

Image 1 - World’s Earliest Art Studio Uncovered In Cape Town Cave
2011-10-14 05:59:35

[ 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...

Image 1 - Sexual Selection By Sugar Molecule Helped Determine Human Origins
2011-10-11 03:46:42

Researchers at the University of California, San Diego School of Medicine say that losing the ability to make a particular kind of sugar molecule boosted disease protection in early hominids, and may have directed the evolutionary emergence of our ancestors, the genus Homo. The findings, published in this week's early online edition of the Proceedings of the National Academy of Sciences, are among the first evidence of a novel link between cell surface sugars, Darwinian sexual selection,...

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...

Image 1 - Ancient Humans Settled East Asia In Two Waves, Not One
2011-09-23 08:41:55

   [ Watch The Video ] An international team of researchers have sequenced the genome of an Aboriginal Australian and determine that early humans settled eastern Asia in two waves rather than just one. The study has broad implications for understanding how our human ancestors migrated across the globe. The scientists sequenced the genome of a lock of hair donated to a British anthropologist by an Aboriginal man from the Goldfields region of Western Australia in the early...

New Technique Uses Genomes To Determine Ancient Human Migrations
2011-09-22 05:18:56

  Researchers at Cornell University have developed new statistical methods based on the complete genome sequences of living humans to shed light on events at the dawn of human history. The scientists applied their methods to the genomes of individuals of East Asian, European, and western and southern African descent.  Although they analyzed just six genomes, the researchers made use of the fact that these genomes contain traces of genetic material from thousands of human...

In an intriguing original look at the history of the first Americans, a new study finds evidence that the north-south orientation of the American continents slowed the spread of populations and technology, compared to the east-west axis of Eurasia. The research, published in the American Journal of Physical Anthropology, is part of a special section which explores who the first Americans were and how they were able to settle in the last great unexplored habitat. The research, by Sohini...

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...

Australopithecus garhi
2013-11-29 11:38:51

Australopithecus garhi is a gracile australopithecine species whose fossils were discovered in 1996 by a research team led by Ethiopian paleontologist Berhane Asfaw ad Tim White, an American paleontologist. The remains are believed to be a human ancestor species and most likely the direct ancestor to the human genus Homo. Tim White was the scientist to find the first of the key A. garhi fossils in 1996 within the Bouri Formation found in the Middle Awash of Ethiopia’s Afar Depression....

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,...

Homo floresiensis
2013-09-16 13:06:40

Homo floresiensis Homo floresiensis, or Flores Man, nicknamed “hobbit” and “Flow”, is an extinct species in the genus Homo. The remains of an individual that would have stood about 3 feet in height were uncovered in 2003 on the island of Flores in Indonesia. Incomplete skeletons of nine individuals have been recovered, including one complete cranium. These remains have been the focus of intense research to establish whether they represent a species distinctive from modern humans....
