An extinct species called Homo naledi buried their dead 100,000 years before humans. The species, called Homo naledi, had brains about one-third the size of a modern human's, according to CNN. Until now, these behaviors had only been associated with larger-brained species such as Homo sapiens and Neanderthals. "These recent findings suggest intentional burials, the use of symbols, and meaning-making activities by Homo naledi. Homo naledi walked upright and manipulated objects by hand like humans, Berger said, but they were shorter, thinner, had smaller heads, and were more powerfully built, per CNN.

☆ Does human intelligence come from our big brains? A new discovery in ancient humans with brains one-third the size of ours is challenging the idea that bigger is better.

Homo naledi had brains one-third the size of humans but were capable of complex thought. The Homo naledi species is still new and mysteriousH. naledi is a pretty new addition to the family tree of hominins, which includes our direct ancestors and other extinct relatives who walked on two legs. Researchers analyze fossils of Homo naledi at the University of the Witwatersrand's Evolutionary Studies Institute in Johannesburg. But those species still had big brains — unlike H. naledi, whose burials would raise further questions about human evolution, Stringer said. For study author Agustin Fuentes, an anthropologist at Princeton University, the H. naledi evidence takes the focus off brain size.

The study team lays out fossils of Homo naledi at the University of the Witwatersrand's Evolutionary Studies Institute in Johannesburg. One body belonged to an adult Homo naledi, and the other was a juvenile. In 2018, the team began to find evidence that supported the idea that Homo naledi intentionally buried their dead. Carvings on the wallWithin one of the graves is a tool-shaped rock, buried next to the hand of a Homo naledi adult. The "tool shaped rock" was likely buried near or clutched in the hand of a young teenage Homo naledi child buried in the Hill Antechamber.

☆ When Does Life Begin?

“It is not black and white.”America’s fight over abortion has long circled a question, one that is broad and without consensus:When does life begin? The question of when life begins has been so politicized it can be hard to thoughtfully engage. Ancient Egypt gave the power to create new human life almost entirely to men. The scientific revolution, from Charles Darwin’s theory of evolution to reproductive science, disrupted centuries of thought on human life. “When does the responsibility for a life begin and end?”

In 2019, Cambodia supplied 8,571 of the 33,818 research monkeys imported to the U.S., or 25%. In 2021, the number of monkeys from Cambodia more than doubled to 18,870, making up nearly 60% of the 31,844 research monkeys brought to America. Earlier this year, long-tailed macaques and pig-tailed macaques were listed as endangered species by the International Union for Conservation of Nature. The decades long effort by animal rights groups to derail the monkey trade has made some impact. The incident shined a rare spotlight on the monkey trade, which largely goes on outside the view of the public.
