Scientists have discovered proof that the evolution of intelligence and larger brain sizes can be driven by cooperation Scientists have discovered proof that the evolution of intelligence and larger brain sizes can be driven by cooperation and teamwork, shedding new light on the origins of what it means to be human. The study appears online in the journal Proceedings of the Royal Society B and was led by scientists at Trinity College Dublin: PhD student, Luke McNally and Assistant...

Meat-rich Diet Lead To Earlier Weaning, Helping Speed The Spread Of Humans
2012-04-19 11:35:43

Diets rich in meat helped early mother´s wean their babies at an earlier age and allowed them to have more children, behaviors that may have helped humans spread more quickly across the world and had a profound effect on human evolution, according to new research. Researchers from Lund University in Sweden, publishing their work in the open-access journal PLoS ONE, found a clear connection between eating meat and weaning at an earlier age. They discovered that all mammalian species...

Findings provide tools for better understanding of the human genome Chromosomes are strands of DNA that contain the blueprint of all living organisms. Humans have 23 pairs of chromosomes that instruct how genes are regulated during development of the human body. While scientists have developed an understanding of the one-dimensional structure of DNA, until today, little was known about how different parts of DNA are folded next to each other inside the nucleus. Using a powerful DNA...

Researchers studying human origins should develop standards for determining whether markings on fossil bones were made by stone tools or by biting animals, Indiana University faculty member Jackson Njau writes in an article this week in the journal Science. Njau, a co-director of field research at paleontological sites in eastern Africa's Olduvai Gorge, notes that the lack of agreement on interpreting such marks is leading to great uncertainty over when early hominids began using tools to...

Study Claims Human Predecessors Used Fire 1 Million Years Ago
2012-04-03 06:00:52

An international team of researchers say that they have identified one-million year old archaeological evidence that human ancestors used and controlled fire, suggesting that our predecessors may have mastered flame approximately 300,000 years earlier than previously thought. The study, which was led by researchers from the University of Toronto and Hebrew University of Jerusalem and published in the journal Proceedings of the National Academy of Sciences (PNAS), resulted in the discovery...

It seems that “Lucy” was not the only hominin on the block in northern Africa about 3 million years ago. A team of researchers that included Johns Hopkins University geologist Naomi Levin has announced the discovery of a partial foot skeleton with characteristics (such as an opposable big toe bone) that don´t match those of Lucy, the human ancestor (or hominin) known to inhabit that region and considered by many to be the ancestor of all modern humans. The discovery is...

'Lucy' lived among close cousins A team of scientists has announced the discovery of a 3.4 million-year-old partial foot from the Woranso-Mille area of the Afar region of Ethiopia. The fossil foot did not belong to a member of "Lucy's" species, Australopithecus afarensis, the famous early human ancestor. Research on this new specimen indicates that more than one species of early human ancestor existed between 3 and 4 million years ago with different methods of locomotion. The analysis will...

A 3.4-million-year-old fossil foot found in eastern Ethiopia appears to settle a long-standing debate about whether there was just one line of hominins 3 to 4 million years ago, scientists said on Wednesday. The fossil record for that period had been virtually limited to the species Australopithecus afarensis, the early human ancestor made famous by the 3.2-million-year-old Lucy skeleton. However, research on the new specimen, which was found in February 2009 in an area locally known as...

New Age Suggested For East African Rift
2012-03-28 09:33:57

A new study published in the journal Nature Geoscience is suggesting that the human species may have taken much longer to evolve thanks to plate tectonics that changed Africa´s landscape millions of years before experts previously believed. Scientists from James Cook University, Ohio University, and Michigan State University said their findings show evidence that a major tectonic event occurred in East Africa as far back as 25 - 30 million years ago, reshaping large rivers such as the...

Large numbers of people moved between Africa and Europe during recent and well-documented time periods such as the Roman Empire, the Arab conquest, and the slave trade, and genetic evidence of these migrations lives on in Europeans today. But were there more ancient migrations? In a study published online today in Genome Research, researchers present the first genetic evidence for prehistoric gene flow between Africa and Europe, dating back as far as 11,000 years ago. To trace the...

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....
