Latest Pleistocene Stories
There is a disconnect in our current knowledge about the American mastodon (Mammut americanum) between what we know of their preferred habitat and the age estimates of fossils.
Based on the analysis of the nasal anatomy of Neanderthals and modern humans, a team of New York City researchers has determined that Neanderthals were not a subspecies of modern humans – as has been previously theorized.
In a study published today in PNAS, Dr William Roberts of Bristol's School of Geographical Sciences and colleagues use computer models to simulate a Heinrich event in Hudson Bay, Canada, adjusting the models to consider freshwater influx only, changing ice sheet height only or both factors together.
Genetic analysis of DNA obtained from a 45,000-year-old modern human thigh bone has allowed researchers to narrow down the time frame in which mating first introduced Neanderthal genes into the human gene pool.
As the massive ice sheet that once covered much of North America began to melt, icebergs and meltwater would have regularly reached South Carolina and even Florida, according to new research published in the current advance online edition of the journal Nature Geosciences.
Researchers have for the first time investigated ancestry across the red fox genome, including the Y chromosome, or paternal line.
A new study published in The Journal of Geology provides support for the theory that a cosmic impact event over North America some 13,000 years ago caused a major period of climate change known as the Younger Dryas stadial, or “Big Freeze.”
Neanderthals have a reputation for being unintelligent brutes, but the discovery of a series of lines scratched into a rock wall in southwestern Europe suggests that the predecessors of modern humans might have had the intelligence and creativity to produce cave art.
Neanderthals died out approximately 10,000 years earlier than previously believed, due in part to the fact that modern humans arrived in Europe sooner than originally thought, an international team of researchers reported Wednesday in the journal Nature.
Skeletal remains recovered from the Indonesian island of Flores over a decade ago are not a new species of “hobbit” sized human, but an ancient Homo sapien showing signs of abnormal development consistent with Down syndrome.
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....
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 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 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 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....
