Chimpanzees use weight to pick the best tool, and monkeys beg more when they're paid attention to, as reported in two independent research reports published July 18 in the open access journal PLoS ONE. In the chimp study, researchers found that the chimpanzees used weight to choose the best hammer to crack open nuts. Nut cracking is one of the most sophisticated instances of tool use in chimpanzees, and learning how to do it has been shown to be very difficult for some chimps. In work led...

Your Genome Available From A Drugstore Near You?

John Neumann for redOrbit.com - Your Universe Online With the growing accessibility of our human genome increasing all the time, the day may not be far off when we carry our personal genome around like we carry a driver´s license now, according to a recent Telegraph report. Professor Armand Leroi, of Imperial College London, claims that with the falling costs of DNA testing, it will be common for young people to pay to access their entire genetic code within the next five to ten...

Digging For The Oldest Genetic Material In Spain
2012-07-02 12:02:22

Brett Smith for redOrbit.com - Your Universe Online Researchers from the Spanish National Research Council (CSIC) have recovered and sequenced the oldest genetic material from two individuals living in Mesolithic Spain, over 7,000 years ago. This groundbreaking work of genetics, published in Current Biology, shows that the sequenced genomes are out-of-sync with modern day Iberians. "These hunters-gatherers shared nomadic habits and had a common origin,” said study co-author...

Mapping The Functional Genome
2012-07-02 08:12:28

Regulatory sequences of mouse genome sequenced for first time Popularly dubbed "the book of life," the human genome is extraordinarily difficult to read. But without full knowledge of its grammar and syntax, the genome's 2.9 billion base-pairs of adenine and thymine, cytosine and guanine provide limited insights into humanity's underlying genetics. In a paper published in the July 1, 2012 issue of the journal Nature, researchers at the Ludwig Institute for Cancer Research and the...

Insights Into Primate Diversity Learned From The Rhesus Macaque
2012-06-29 09:27:37

New research published in BMC Genetics shows that the rhesus macaque has three times as much genetic variation than humans. However despite much of this extra variation being within genes, it does not affect protein function. Consequently damaging variations are at similar levels in macaques and humans - indicating a strong selection pressure to maintain gene function regardless of mutation rate or population size. Humans and rhesus macaques shared a common ancestor approximately 25...

Bonobo Genome Found Strikingly Similar To Humans And Chimps
2012-06-14 08:59:39

Lawrence LeBlond for redOrbit.com The bonobo, one of man´s closest relatives, has had its genome completely mapped by German researchers, placing a new checkmark in the DNA-sequencing list that already includes humans, chimpanzees, gorillas and orangutans, giving scientists a complete record of the great ape genome. The achievement, published Wednesday in the journal Nature, should help scientists, together with the other great ape genome maps, better understand human evolution....

Homo Heidelbergensis Slightly Taller Than The Neanderthal
2012-06-06 10:04:41

The reconstruction of 27 complete human limb bones found in Atapuerca (Burgos, Spain) has helped to determine the height of various species of the Pleistocene era. Homo heilderbergensis, like Neanderthals, were similar in height to the current population of the Mediterranean. Along with its enormous quantity of fossils, one of the most important features of the Sima de los Huesos (SH) site in Atapuerca, Burgos, is the splendid state of the findings. They are so well conserved that the 27...

Infectious Diseases Determined Current Gene Makeup

Connie K. Ho for redOrbit.com The author J.J. Dewey once said, "Consciousness cannot live in the present for the present cannot exist without the future and the past." This idea of the past influencing the present was seen in a recent report published in the online Early Edition of the Proceedings of the National Academy of Sciences that proposed that the inactivation of two genes linked to the immune system could have given some ancestors of modern humans greater protection from specific...

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....
