Giant ape lived alongside humans


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.

McMaster geochronologist Jack Rink has determined that a gigantic ape which became extinct 100,000 years ago co-existed alongside humans.

Gigantopithecus blackii, the largest primate that ever lived.

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 the puzzle has always focused on pin-pointing when Gigantopithecus existed," explains Rink. "This is a primate that co-existed with humans at a time when humans were undergoing a major evolutionary change. Guangxi province in southern China, where the Gigantopithecus fossils were found, is the same region where some believe the modern human race originated."

Research into Gigantopithecus blackii began in 1935, when the Dutch paleontologist G.H. von Koenigswald discovered a yellowish molar among the "dragon bones" for sale in a Hong Kong pharmacy. Traditional Chinese medicine maintains that dragon bones, basically fossil bones and teeth, possess curative powers when the fossils are ground into a fine powder, and ingested.

For nearly 80 years, Gigantopithecus blackii has intrigued scientists, who have pieced together a description using nothing more than a handful of teeth and a set of jawbones.

"The size of these specimens – the crown of the molar, for instance, measures about an inch across – helped us understand the extraordinary size of the primate," says Rink. Sample studies further revealed that Gigantopithecus was an herbivore, feasting mainly on bamboo. Some believe that the primate’s voracious appetite for bamboo ultimately placed him at the losing end of the evolutionary scale against his more nimble human competition.

Rink’s research was funded by Canada’s Natural Sciences and Engineering Research Council.

Rink’s discovery coincides with an invitation to join the renowned New York-based Explorers Club. Established in 1904, the Club’s seven founding members included two polar explorers, the curator of birds and mammals at The American Museum of Natural History, an archaeologist, a war correspondent and author, a professor of physics and an ethnologist. Sir Edmund Hillary is Club’s honorary chairman. Membership includes an eclectic range of field scientists and explorers from more than 60 countries. Rink joins McMaster colleagues Hendrik Poinar (associate professor, Anthropology) and Ed Reinhardt (associate professor, Geography and Earth Science) who are also members.

Rink is currently in Thailand exploring an area where it is believed Gigantopithecus also roamed. Rink returns to campus on November 19.

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
