An artist's impression of Gigantopithecus blacki, the giant ape from southern China. Illustration: Garcia/Joannes-Boyau (Southern Cross University) An ancient mega ape's massive size — clocking in at 10 feet tall and around 550 pounds — turned into an evolutionary disadvantage as it went extinct more than 200,000 years ago, according to new study published in Nature on Wednesday. Why it matters: The new research helps scientists resolve a longstanding mystery surrounding the legendary Gigantopithecus blacki's disappearance from what's now China. What's happening: Gigantopithecus blacki, the largest known primate to roam Earth, went extinct between 295,000 and 215,000 years ago because...

Prof. Begun said: "Our findings further suggest that hominines [bonobos, chimpanzees, and gorillas] not only evolved in western and central Europe - but spent over five million years evolving there and spreading to the eastern Mediterranean before eventually dispersing into Africa."....This migration, he added, was "probably a consequence of changing environments and diminishing forests."

Four fossilized monkey teeth discovered deep in the Peruvian Amazon provide new evidence that more than one group of ancient primates journeyed across the Atlantic Ocean from Africa. The teeth are from a newly discovered species belonging to an extinct family of African primates known as parapithecids. Fossils discovered at the same site in Peru had earlier offered the first proof that South American monkeys evolved from African primates.

Hamilton, ON - A gigantic ape, measuring about 10 feet tall and weighing up to 1,200 pounds, co-existed alongside humans, a geochronologist at McMaster University has discovered. Using a high-precision absolute-dating method (techniques involving electron spin resonance and uranium series), Jack Rink, associate professor of geography and earth sciences at McMaster, has determined that Gigantopithecus blackii, the largest primate that ever lived, roamed southeast Asia for nearly a million years before the species died out 100,000 years ago. This was known as the Pleistocene period, by which time humans had already existed for a million years. “A missing piece of...

A gigantic ape standing 10 feet tall and weighing up to 1,200 pounds lived alongside humans for over a million years, according to a new study. Fortunately for the early humans, the huge primate's diet consisted mainly of bamboo. Scientists have known about Gigantopithecus blackii since the accidental discovery of some of its teeth on sale in a Hong Kong pharmacy about 80 years ago. While the idea of a giant ape piqued the interest of scientists – and bigfoot hunters – around the world, it was unclear how long ago this beast went extinct. Precise dating Now Jack Rink,...

Infectious Evolution: Ancient virus hit apes, not our ancestors, in the genesMarch 5 Bruce Bower A vicious virus infected ancestral chimpanzees and gorillas in Africa between 4 million and 3 million years ago. Not only did it kill a great many of these primates, but it also infiltrated the surviving animals' genomes, altering the course of evolution. That's the picture emerging from a new analysis of modern-primate DNA. Around 1.5 million years ago, this virus of the class called retroviruses also infected ancestors of modern baboons and macaques, two African monkeys, reports geneticist Evan E. Eichler of the University of...

Homo erectus, one of modern humans' direct ancestors, was a wandering bunch. After the species dispersed from Africa about two million years ago, it colonized the ancient world, which included Asia and possibly Europe. But about 400,000 years ago, Homo erectus essentially vanished. The lone exception was a spot called Ngandong, on the Indonesian island of Java. But scientists were unable to agree on a precise time period for the site...A new study...dates the last existence of Homo erectus at Ngandong between 108,000 and 117,000 years ago.

Find opens debate about whether man's earliest ancestors came from Asia and were diurnal or nocturnal CHICAGO--A skull and jawbones recently found in China is the oldest well-preserved primate fossil ever discovered ? as well as the best evidence of the presence of early primates in Asia. But the fossil raises the tantalizing possibility that remote human ancestors may have originated in Asia and stirs up debate about the nature of early primates. In the words of Robert D. Martin, Provost and Vice President of Academic Affairs at Chicago's Field Museum, "It was once thought that primates originated in North...

Oldest hominid skull in Australia found near Bega Friday, 13 January 2006 THE endocast of a primitive hominid-like skull was recovered from among the rubble of a volcanic plug in the Bega district in May 2005 The find could suggest that a race of ancestral hominids had evolved in Australia from tree-dwelling primate ancestors by seven million years ago. This is well before our primate ancestors supposedly left the trees for a terrestrial existence in Africa around six million years ago! The fossil was discovered by noted prehistory researcher Rex Gilroy of Katoomba NSW, where he operates the 'Australian-Pacific Archaeological...

Scientists have unearthed remains of a primate that could have been ancestral not only to humans but to all great apes, including chimps and gorillas. The partial skeleton of this 13-million-year-old "missing link" was found by palaeontologists working at a dig site near Barcelona in Spain. Details of the sensational discovery appear in Science magazine. The new specimen was probably male, a fruit-eater and was slightly smaller than a chimpanzee, researchers say. Palaeontologists were just getting started at the dig when a bulldozer churned up a tooth. Further investigation yielded one of the most complete ape skeletons known from...

SUNY-Albany biologist Caro-Beth Stewart and NYU anthropologist Todd R. Disotell have proposed... that the ancestor of humans and the living African apes evolved in Eurasia, not Africa. This controversial new model for the evolution of humans and apes is the cover story of the July 30th issue of Current Biology. Stewart and Disotell describe their theory in an article entitled "Primate evolution -- in and out of Africa." ...The fossil record indicates that apes were present in Europe and Western Asia during the Miocene Era, from about 8 to 17 million years ago. Ancestors of these ape species must have...

Undated handout photo shows the skull of Toumaï, a seven-million-year-old fossil believed to be the remains of the earliest human ever found, found in 2001. New fossil remains as well as the 3D reconstruction of the skull confirm that the creature is the oldest species of the human branch, a common ancester of the chimpanzee and of homo sapiens French fossil hunters have pinned down the age of Toumai, which they contend is the remains of the earliest human ever found, at between 6.8 and 7.2 million years old. The fossil was discovered in the Chadian desert in 2001...

An international team of researchers has announced the discovery of Afrasia djijidae, a new fossil primate from Myanmar that illuminates a critical step in the evolution of early anthropoids -- the group that includes humans, apes, and monkeys. The 37-million-year-old Afrasia closely resembles another early anthropoid, Afrotarsius libycus, recently discovered at a site of similar age in the Sahara Desert of Libya. The close similarity between Afrasia and Afrotarsius indicates that early anthropoids colonized Africa only shortly before the time when these animals lived. The colonization of Africa by early anthropoids was a pivotal step in primate and human evolution,...

The late Early Pleistocene site near Untermassfeld, in Germany, is now well known for a rich array of fauna dating back to about 1.07 million years ago, including simple 'Mode 1' (or Oldowan-type) stone tools evidencing early human occupation. Now researchers Günter Landeck and Joan Garcia Garriga report, for the first time, evidence of early human butchery in the form of cut marks on animal bones and intentional hammerstone-related bone breakage. These human-modified bones were recovered in a small faunal subsample excavated from levels with simple 'Mode 1' stone tools. The butchered assemblage was found during fieldwork and surveying of...

Tree-dwelling apes in Europe strode upright around 5 million years before members of the human evolutionary family hit the ground walking in Africa. That’s the implication of fossils from a previously unknown ape that lived in what’s now Germany about 11.6 million years ago, say paleontologist Madelaine Böhme of the University of Tübingen in Germany and her colleagues. But the relation, if any, of these finds to the evolution of a two-legged stride in hominids by perhaps 6 million years ago is hazy (SN: 9/11/04). Excavations in a section of a Bavarian clay pit produced 37 fossils from the ancient...

The oldest known fossils of an ape and a monkey have been uncovered, providing an intriguing glimpse of a crucial time in primate evolution. The discoveries suggest that by 25 million years ago, two major groups of primates were distinct: one that today includes apes and humans and another that encompasses Old World monkeys such as baboons and macaques. Previous studies using living primates’ DNA suggested that ancient apes and Old World monkeys parted from a common ancestor between 25 million and 30 million years ago. The new ape and monkey fossils, from Tanzania’s Rukwa Rift Basin, suggest that the...

New species firmly establish African roots for anthropoid line.The fossil teeth and jawbones of two new species of tiny monkey-like creatures that lived 37 million years ago have been sifted from ancient sediments in the Egyptian desert, researchers have reported. Related They said their findings firmly establish that the common ancestor of living anthropoids -- including monkeys, apes and humans -- arose in Africa and that the group had already begun branching into many species by that time. Also, they said, one of the creatures appears to have been nocturnal, the first example of a nocturnal early anthropoid. The researchers...

CHICAGO (AFP) - French fossil hunters have pinned down the age of Toumai, which they contend is the remains of the earliest human ever found, at between 6.8 and 7.2 million years old. The fossil was discovered in the Chadian desert in 2001 and an intense debate ensued over whether the nearly complete cranium, pieces of jawbone and teeth belonged to one of our earliest ancestors. Critics said that Toumai's cranium was too squashed to be that of a hominid -- it did not have the brain capacity that gives humans primacy -- and its small size indicated a creature...

Just 9-thousandths of a square inch in size, the teeth are about 54.5 million years old and suggest these early primates were no larger than modern dwarf lemurs weighing about 2 to 3 ounces... Previous fossil evidence shows primates were living in North America, Europe and Asia at least 55 million years ago. But, until now, the fossil record of anthropoid primates has extended back only 45 million years... In addition to stretching the primate timeline, the specimens represent a new genus as well as a new species of anthropoid, which the researchers have named Anthrasimias gujaratensis by drawing from...
