Researchers say that a scientific reconstruction of one of the oldest sets of human remains found in the Americas supports theories that the first people who came to the hemisphere migrated from a broader area than once thought. Mexico's National Institute of Anthropology and History released photos on Thursday of the reconstructed image of a woman who probably lived on Mexico's Caribbean coast 10,000 to 12,000 years ago.  Anthropologist have believed for a while that humans migrated...

North Pacific circulation radically changed by past post-glacial warming Toward the end of the last ice age, a major reorganization took place in the current system of the North Pacific with far-reaching implications for climate, according to a new study published in the July 9, 2010, issue of Science by an international team of scientists from Japan, Hawaii, and Belgium. Earth's climate is regulated largely by the world ocean's density-driven circulation, which brings warm surface water to...

Ancient man migrated out of Africa into northern Europe more than 800,000 years ago, far earlier than previously believed, according to a new study released Wednesday. A collection of flint tools unearthed near Happisburgh in the eastern British county of Norfolk, where winter temperatures reach 32F degrees below zero, is from the earliest known settlement of humans, according to the landmark study published in the British journal Nature. The discovery suggests that humans 26,000 generations...

A chain of past natural events may hold lessons for the future Scientists still puzzle over how Earth emerged from its last ice age, an event that ushered in a warmer climate and the birth of human civilization. In the geological blink of an eye, ice sheets in the northern hemisphere began to collapse and warming spread quickly to the south. Most scientists say that the trigger, at least initially, was an orbital shift that caused more sunlight to fall across Earth's northern half. But how...

Research at the School of Geographical Sciences, Southwest University (SWU) in Chongqing, China-Research, has demonstrated that the record of the Asian Summer Monsoon (ASM) covers the last deglaciation and the early Holocene (from 16.2 to 7.3 ka BP), with an average oxygen isotope resolution of 9 years (issue 53, May 2010 of SCIENCE CHINA Earth Sciences). Understanding the factors responsible for past climatic changes is a key to understand future climate change. Such climatic changes include...

The balance of biodiversity within North American small-mammal communities is so out of whack from the last episode of global warming about 12,000 years ago that the current climate change could push them past a tipping point, with repercussions up and down the food chain, say Stanford biologists. The evidence lies in fossils spanning the last 20,000 years that the researchers excavated from a cave in Northern California. What they found is that although the small mammals in the area suffered...

Study suggests that Ice Age climate change did not pose significant challenges to first Americans Paleoindian groups* occupied North America throughout the Younger Dryas interval, which saw a rapid return to glacial conditions approximately 11,000 years ago. Until now, it has been assumed that cooling temperatures and their impact on communities posed significant adaptive challenges to those groups. David Meltzer from the Southern Methodist University in Dallas, USA, and Vance Holliday from...

Did a change in climate or an extraterrestrial impact bring an end to the beasts and people that roamed the Southwest shortly after the last ice age? A team of researchers from the University of Arizona has revisited evidence pointing to a cataclysmic event thought by many scientists to have wiped out the North American megafauna "“ such as mammoths, saber tooth cats, giant ground sloths and Dire wolves "“ along with the Clovis hunter-gatherer culture some 13,000 years ago. The...

The main cause of a rapid global cooling period, known as the Big Freeze or Younger Dryas - which occurred nearly 13,000 years ago - has been identified thanks to the help of an academic at the University of Sheffield. A new paper, to be published in Nature on April 1, 2010, has identified a mega-flood path across North America which channeled melt-water from a giant ice sheet into the oceans and triggering the Younger Dryas cold snap. The research team, which included Dr Mark Bateman from...

This question isn't new, but for years anthropologists, archaeologists and historians of art understood these artistic manifestations as purely aesthetic and decorative motives. Eduardo Palacio-P©rez, researcher at the University of Cantabria (UC), now reveals the origins of a theory that remains nowadays/lasts into our days. "This theory is does not originate with the prehistorians, in other words, those who started to develop the idea that the art of primitive peoples was linked...

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....
