Dubbed the ancient man I was born a man As the fires in the pitch-dark rooms of the underground cave lighting system, hint at the new discoveries of control.
Researchers have found remains of hearths and sooty walls and ceiling smudges in areas and rooms throughout South Africa in the Rising Star Cave complex, paleoanthropologist Lee Berger announced in a December 1 lecture at the Carnegie Institution of Science in Washington, DC.
Fire marks are used everywhere in this cave system,” says Berger, of the University of the Witwatersrand, Johannesburg.
H. naledi burning in the caves because the remains of no other hominids were found there, the team says. But the researchers of the fire age still remain modern. And researchers outside of Berger’s group are yet to be evaluated.
H. naledi The fossils are dated between 335,000 and 236,000 years ago (SN: 5/9/17) About time A wise man originated (SN: 6/7/17). Many researchers suspect that the regular use of fire by hominids for light, heat, and cooking began about 400,000 years ago (SN: 4/2/12).
Such behavior is not attributed H. naledi first, mainly because of the brain. But it is now clear that a brain the size of about a third of the human brain is still being prepared today H. naledi to gain control, Berger contends.
Last August, Berger descended a narrow shaft and examined two underground chambers where H. naledi fossils found He saw stalactites and thin sheets of rock that had partially grown over the roofs of the upper surfaces. Those surfaces showed blackened, burnt areas and were also dotted with what appeared to be soot particles, Berger said.
Meanwhile, expedition codirector and Wits paleoanthropologist Keneiloe Molopyane led the excavations of a room near the cave. There, the researchers discovered two small hearths of charred wood, and cremated bones of donkeys and other animals. The remains of a hearth and the bones of nearly burnt animals were then found in a more remote chamber of the cave H. naledi fossils have been found.
However, the biggest challenge for the researchers will be to find burnt wood and bones and other burning remains from the rising star chambers and show that the hearths are made from the same sedimentary layers. H. naledi fossils, says paleoanthropologist W. Andrew Barr of George Washington University in Washington, DC, who was not involved in the work.
“This is the first critical step in being able to absolutely speculate on who started the fires and what caused them,” Barr said.
