New Method Allows Researchers To Sort Out DNA Contamination
2014-01-28 06:53:19

April Flowers for redOrbit.com - Your Universe Online Special precautions are usually a part of retrieving ancient DNA to prevent DNA from researchers or the environment from mixing with that of the fossil. Many ancient fossils, however, have been lying forgotten in museum collections for decades that have become contaminated with present-day human DNA before even entering the laboratory. A solution for this problem, published in Proceedings of the National Academy of Sciences (PNAS),...

What Is Adam's Rightful Place In Evolutionary History?
2014-01-23 07:52:48

University of Sheffield Our most common male ancestor walked the earth 209,000 years ago – earlier than scientists commonly thought - according to new research from the University of Sheffield. The pioneering study, conducted by Dr Eran Elhaik from the University of Sheffield and Dr Dan Graur from the University of Houston, also debunked the discovery of the Y chromosome that supposedly predated humanity. In the new research, published in the European Journal of Human Genetics, Dr...

An Oxford University study has concluded that our ancient ancestors who lived in East Africa between 2.4 million-1.4 million years ago mainly ate tiger nuts (grass bulbs) supplemented with the odd grasshopper and worm An Oxford University study has concluded that our ancient ancestors who lived in East Africa between 2.4 million-1.4 million years ago survived mainly on a diet of tiger nuts. Tiger nuts are edible grass bulbs still eaten in parts of the world today. The study published in...

A new study compares the relative rate of molecular evolution between humans and chimps with that of their lice. The researchers wanted to know whether evolution marches on at a steady pace in all creatures or if subtle changes in genes – substitutions of individual letters of the genetic code – occur more rapidly in some groups than in others. A report of the study appears in the Proceedings of the Royal Society B. The team chose its study subjects because humans, chimps and their...

Humanlike Features Discovered In 4.4M-Year-Old Ardipithecus Skull
2014-01-07 06:54:22

April Flowers for redOrbit.com - Your Universe Online The 4.4-million-year-old African species Ardipithecus ramidus, or "Ardi," is the focus of one of the most hotly debated issues in current human origins research. Scientists want to know how Ardi, an unusual primate, is related to the human lineage. The study, published in the online edition of Proceedings of the National Academy of Sciences (PNAS), shows that although Ardi possessed a tiny brain and a grasping big toe for climbing...

Of Sharks, Bees And Humans: Hunting Patterns Similar Among Species
2013-12-24 10:39:15

Brett Smith for redOrbit.com - Your Universe Online A team of international researchers has found that a tribe of hunter-gatherers in Tanzania uses the same search pattern to hunt for food as many other animal species, according to a report published on Monday in the Proceedings of the National Academy of Sciences (PNAS). The search pattern, also known as the Levy walk, involves a sequence of short travels in one area and then a longer hike to another area. Not just used to find food,...

Neanderthal Man May Have Been Able To Speak, According To New Evidence
2013-12-21 05:15:08

redOrbit Staff & Wire Reports - Your Universe Online New analysis of a Neanderthal’s hyoid bone provides evidence suggesting the extinct humanoids had the ability to speak, an international team of researchers write in the latest edition of the journal PLoS ONE. Previously, a 1989 description of this horseshoe shaped structure in the neck originating from a fossil found in Kebara Cave in Israel “fueled scientific debate on the evolution of speech and complex language,” the...

Evidence Shows Incest, Interbreeding Common Among Neanderthals
2013-12-18 15:10:49

redOrbit Staff & Wire Reports - Your Universe Online Genetic sequencing of DNA extracted from a Neanderthal woman’s toe bone reveals the species was not only incestuous, but also interbred with other types of human ancestors, according to research scheduled for publication in Thursday’s edition of the journal Nature. An international team of scientists, including researchers from the University of California, Berkeley, completed what they are calling the most complete sequencing...

Recent highlights in the journal Molecular Biology and Evolution With the Neanderthal genome now published, for the first time, scientists have a rich new resource of comparative evolution. For example, recently, scientists have shown that humans and Neanderthals once interbreed, with the accumulation of elements of Neanderthal DNA found in up to 5 percent in modern humans. Are there any advantages to the retention of Neanderthal DNA that favors modern humans? In a new article published...

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....
