40,000-year-old bracelet made by extinct human species found

In what is quite an amazing discovery, scientists have confirmed that a bracelet found in Siberia is 40,000 years old. This makes it the oldest piece of jewelry ever discovered, and archeologists have been taken aback by the level of its sophistication.
The bracelet was discovered in a site called the Denisova Cave in Siberia, close to Russia's border with China and Mongolia. It was found next to the bones of extinct animals, such as the wooly mammoth, and other artifacts dating back 125,000 years.
The cave is named after the Denisovan people — a mysterious species of hominins from the Homo genus, who are genetically different from both Homo sapiens and Neanderthals.

 

 

Just my opinion, but I do not believe human evolution is quite as simple as most "evolutionists" make it out to be.

A find in Australia hints at very early human exit from Africa

 

As archaeologist Chris Clarkson was excavating a rock shelter in northern Australia one day in 2015, May Nango of the aboriginal Mirarr group brought her grandchildren to look at the pit. She pointed to a spot near the back wall of the red sandstone cliff and told the children that it was a wonderful place for their ancestors—the "old people"—to sleep 65,000 years ago, says Clarkson of the University of Queensland in Brisbane, Australia.

 
Nango's tale was more than an aboriginal "dreamtime" story. She was one of the first to hear from Clarkson's team about new scientific dates for the Madjedbebe rock shelter in Australia's Arnhem Land, a region the Mirarr still call home. The dates, based on new excavations and state-of-the-art methods, push back the earliest solid evidence for humans in Australia by 10,000 to 20,000 years and suggest that modern humans left Africa earlier than had been thought. Published this week in Nature, the findings also hint at when modern humans interacted with other archaic humans.
 
This early date will force the field to "rethink fundamentally the whole issue of when our species started to colonize Asia," says archaeologist Robin Dennell of the University of Sheffield in the United Kingdom.

New study shows that chimpanzees of all ages and all sexes can learn rock-paper-scissors

Chimps of all ages and genders can learn the circular relationship used in rock-paper-scissors, a new study has shown.
The study, Learning the rules of the rock–paper–scissors game: chimpanzees versus children., was carried out by Jie Gao of Kyoto University in Japan and Peking University in China, lead author.
Gao's team wanted to see whether chimpanzees and children had comparable abilities to learn the game, and by doing so see whether chimps could understand extended patterns.
Because the relationship between the game's three signals is non-linear, learning such patterns requires enhanced metnal capacity.

Neanderthal brains were the same size as early humans

The brains of Neanderthals were just as big as humans’ brains, according to new research.
Virtual casts of skull fossils were used to reproduce the brain of a 50,000-year-old ancestor.
Researchers found that overall it was equal to that of early humans but smaller in one region vital for memory and thinking.
The Japanese team said this may have meant an inability to adapt and led to the species dying out.
Naomichi Ogihara said: “Differences in cognitive or neural function may explain why Neanderthals were replaced by Homo Sapiens.”
Neanderthals were known to have good eyesight, making them excellent hunters, which helped compensate for Europe’s low light levels. But it would have reduced the brain space available for social cognition.

Ancient humans settled the Philippines 700,000 years ago

 

http://www.sciencema...-fossils-reveal

 

Introduction:

 

(Science) In what some scientists are calling a “one-in-a-million find,” archaeologists have discovered a cache of butchered rhino bones and dozens of stone tools on the Philippines’s largest island, Luzon. The find pushes back the earliest evidence for human occupation of the Philippines by more than 600,000 years, and it has archaeologists wondering who exactly these ancient humans were—and how they crossed the deep seas that surrounded that island and others in Southeast Asia.

 

“The only thing missing is the hominin fossil to go along with it,” says archaeologist Adam Brumm, of Griffith University in Nathan, Australia. He’s the one who set the odds for what he calls a “very exciting discovery,” but he wasn’t involved with the work.

 

Researchers found 75% of a fossilized rhino skeleton—ribs and leg bones still scarred from the tools that removed their meat and marrow—lying in ancient mud that had long since buried an even older river channel. To determine the site’s age, researchers dated the enamel in one of the rhino’s teeth, as well as quartz grains embedded in the sediment layers above and below the bones, using electron spin resonance (ESR), which measures the buildup of electrons as a material is exposed to radiation over time. The team dated the bottom sediment layer to about 727,000 years old, the rhino tooth to about 709,000 years old, and the top sediment layer to about 701,000 years old. Several independent experts say they were impressed by the team’s careful use of the technique. “They’ve nailed it,” says Alistair Pike, an archaeological dating expert at the University of Southampton in the United Kingdom.

Neanderthals were known to have good eyesight, making them excellent hunters, which helped compensate for Europe’s low light levels. But it would have reduced the brain space available for social cognition.

Their brains were as big as ours, but keep in mind that Neanderthals also had more bone and muscle mass than humans, and they weighed more. Much of the mammalian brain doesn't support intelligent thought--it regulates autonomic functions (heartbeat, metabolism, reflexes, hormone levels), and as the animal's overall mass increases, the brain must get bigger simply to service more body mass. Relative to body mass, Neanderthals had smaller brains than humans, and the structure of their brain was different in ways that effectively lowered their IQs (as the article points out). 

 

If Neanderthals were alive today, they would probably be borderline retarded by our standards.
