    "Specifically, we have shown for the first time that the primate larynx is larger, less closely linked to body size, and under faster rates of evolution than the carnivoran larynx, which is a well-matched comparison group, indicating fundamental differences in the evolution of the vocal organ across species."

    Boston, Mass. - With nearly 5 million confirmed cases globally and more than 300,000 deaths from COVID-19, much remains unknown about SARS-CoV-2, the virus that causes the disease. Two critical questions are whether vaccines will prevent infection with COVID-19, and whether individuals who have recovered from COVID-19 are protected against re-exposure. A pair of new studies led by researchers at Beth Israel Deaconess Medical Center (BIDMC) sheds new light on these questions. Both studies were published today in the journal Science. "The global COVID-19 pandemic has made the development of a vaccine a top biomedical priority, but very little is...
  • Ancient teeth from Peru hint now-extinct monkeys crossed Atlantic from Africa

    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.
  • Oldest Hominid Skull In Australia Found Near Bega (7 Million Years Old)

    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...

    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...

    Full title: Four ancient skulls unearthed in Mexico suggest that North America was a melting pot of different peoples and cultures 10,000 years ago The first humans to settle in North America were more diverse than previously believed, according to a new study of skeletal fragments. US scientists analysed four skulls recovered from caves in Mexico that belonged to humans that lived sometime between 9,000 to 13,000 years ago. The researchers were surprised to find a high level of diversity, with the skulls ranging in similarity to that of Europeans, Asian and ...

    The beautifully preserved remains of a 47-million-year-old, lemur-like creature have been unveiled in the US. The preservation is so good, it is possible to see the outline of its fur and even traces of its last meal. The fossil, nicknamed Ida, is claimed to be a "missing link" between today's higher primates - monkeys, apes and humans - and more distant relatives. But some independent experts, awaiting an opportunity to see the new fossil, are sceptical of the claim. And they have been critical of the hype surrounding the presentation of Ida. The fossil was launched amid great fanfare at...

    Primatologist Jane Goodall has made her name studying chimpanzees for over half a century. So, if anyone can deduce a distinct correlation between a brash chimp and the egoistic hubris of, say, the president of the United States, it’s Goodall. Pre-election, last October, Goodall made a comparison between then-Republican candidate Donald Trump and the primates she has devoted her life to understanding. “In many ways the performances of Donald Trump remind me of male chimpanzees and their dominance rituals,” she told the Atlantic. “In order to impress rivals, males seeking to rise in the dominance hierarchy perform spectacular displays: Stamping,...

    PETA is going after Hallmark for selling cards that it says are harmful to primates. The animal rights organization has sent a letter to the greeting card maker requesting that it stop selling cards that feature chimpanzees, especially those in which the animals are dressed up in costumes and wigs. PETA cited famed primatologist Dr. Jane Goodall in saying that the “smiles” you see coming from the chimpanzees on those cards are actually expressions of fear. “No chimpanzee should be forced into a costume and scared to death for a birthday card,” PETA primatologist Julia Gallucci stated in a press...

    The pace of evolution is typically measured in millions of years, as random, individual mutations accumulate over generations, but researchers at Cornell and Bar-Ilan Universities have uncovered a new mechanism for mutation in primates that is rapid, coordinated, and aggressive. The discovery raises questions about the accuracy of using the more typical mutation process as an estimate to date when two species diverged, as well as the extent to which this and related enzymes played a role in primate evolution. Alon Keinan, associate professor of Biological Statistics and Computational Biology at Cornell, and Erez Levanon, co-senior author and an associate...

    Charles Q. Choi, LiveScience January 27, 2015An ancient human fossil discovered from the seafloor near Taiwan reveals that a primitive group of humans, potentially an unknown species, once lived in Asia, researchers say. These findings suggest that multiple lineages of extinct humans may have coexisted in Asia before the arrival of modern humans in the region about 40,000 years ago, the scientists added. Although modern humans, Homo sapiens, are the only surviving human lineage, others once walked the globe. Extinct human lineages once found in Asia include Neanderthals, the closest extinct relatives of modern humans; Denisovans, whose genetic legacy may...

    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...

    Fossil hints at primate origins The bone is just over a centimetre long An ankle bone discovered in central Burma could be evidence of an ancient ancestor common to many of today's primates, including humans. The 45-million-year-old fossil has features that link it to all of the anthropoids, the grouping of human-like species such as apes and monkeys. If correct, this would tie their line of evolutionary descent to Asia and not Africa as some have suggested. The findings appear in the Proceedings of the National Academy of Sciences. The PNAS journal presents a paper on the discovery by Laurent...

    ALBANY, N.Y. -- A New York appeals court says a chimpanzee isn't entitled to the rights of a human and doesn't have to be freed by its owner. The three-judge Appellate Division panel was unanimous Thursday in denying "legal personhood" to Tommy, who lives alone in a cage in upstate Fulton County. A trial level court had previously denied the Nonhuman Rights Project's effort to have Tommy released. The group's lawyer, Steven Wise, told the appeals court in October that the chimp's living conditions are akin to a person in unlawful solitary confinement.

    The study of the world’s oldest early primate skeleton has brought light to a pivotal event in primate and human evolution: that of the branch split that led to monkeys, apes and humans (anthropoids) on one side, and living tarsiers on the other. The fossil, that was unearthed from an ancient lake bed in central China’s Hubei Province, represents a previously unknown genus and species named Archicebus Achilles. The results of the research were published on 6 June 2013 in Nature. Oldest primate fossil rewrites evolutionary break in human lineage The fossil, which is 55 million years old and dates...
