The fragile regions in mammalian genomes thought to play a key role in evolution go through a 'birth and death' process The fragile regions in mammalian genomes that are thought to play a key role in evolution go through a "birth and death" process, according to new bioinformatics research performed at the University of California, San Diego. The new work, published in the journal Genome Biology on November 30, could help researchers identify the current fragile regions in the human genome...

DNA evidence supports a coastal northeastern Atlantic glacial refugium for a boreal tree species Can a road-trip across eastern North America, ancient ice sheets, and DNA samples unlock the ancestral history of jack pine trees? Julie Godbout and colleagues from the Universit© Laval, Quebec, Canada, certainly hoped that driving across northeastern U.S. and Canada to collect samples from jack pine trees would shed some light on how glaciers may have impacted present-day pine genetics....

A new analysis of teeth from 11 Neanderthal and early human fossils shows that modern humans are slower than our ancestors to reach full maturity. The findings also suggest that modern kids' lengthy childhoods are a relatively recent phenomenon unique to our own species, and may even have given early humans an evolutionary advantage over Neanderthals. The study is the latest to demonstrate the small, but vital, differences in early development between modern humans and Neanderthals, who...

Whether cognitive differences exist between modern humans and Neanderthals is the subject of contentious disputes in anthropology and archaeology. Because the brain size range of modern humans and Neanderthals overlap, many researchers previously assumed that the cognitive capabilities of these two species were similar. Among humans, however, the internal organization of the brain is more important for cognitive abilities than its absolute size is. The brain's internal organization depends on...

The brains of newborn humans and Neanderthals are about the same size and appear rather similar overall. It's mainly after birth, and specifically in the first year of life, that the differences between our brains and those of our extinct relatives really take shape, according to a report published in the Nov. 9 issue of Current Biology, a Cell Press publication. The findings are based on comparisons of virtual imprints of the developing brain and surrounding structures (known as endocasts)...

Evolutionary divergence of humans from chimpanzees likely occurred some 8 million years ago rather than the 5 million year estimate widely accepted by scientists, a new statistical model suggests. The revised estimate of when the human species parted ways from its closest primate relatives should enable scientists to better interpret the history of human evolution, said Robert D. Martin, curator of biological anthropology at the Field Museum, and a co-author of the new study appearing in the...

Stone Age humans were only able to develop relatively advanced tools after their brains evolved a greater capacity for complex thought Stone Age humans were only able to develop relatively advanced tools after their brains evolved a greater capacity for complex thought, according to a new study that investigates why it took early humans almost two million years to move from razor-sharp stones to a hand-held stone axe. Researchers used computer modelling and tiny sensors embedded in...

New findings on mitochondrial haplogroups and genetic variants that positively affect the aging process to be presented at ASHG 60th Annual Meeting in Washington, D.C. Thousands of the world's top scientists and clinicians in the human genetics field will convene to present their latest research findings at the American Society of Human Genetics (ASHG) 60th Annual Meeting, on November 2-6, 2010, in Washington, D.C. A number of the scientific papers presented at the ASHG 2010 meeting will...

A team led by researchers at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, has captured the most comprehensive snapshot to date of DNA regions that regulate genes in human pancreatic islet cells, a subset of which produces insulin. The study highlights the importance of genome regulatory sequences in human health and disease, particularly type 2 diabetes, which affects more than 20 million people in the United States and 200 million people...

Human ancestors from over four million years ago were quite promiscuous, with monogamous relationships developing as hominins evolved over time, claims a new study published in the British scientific journal Proceedings of the Royal Society B. The research, which was led by Emma Nelson of the University of Liverpool's School of Archaeology, Classics and Egyptology, involved the study of the fossilized fingers of Neanderthals and ancient apes, as well as the species Ardipithecus ramidus and...

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....
