H. sapiens sapiens. There were once many species in the genus Homo, but all species and subspecies besides modern humans are now extinct. In 1758, Swedish scientist Carl Linnaeus was the first person to give humans the name H. sapiens. According to Encyclopedia Britannica, the term homo sapiens is derived from Latin and means wise man. Related: The evolution of modern humans About 6 million years ago, an ancestor species of humans, chimpanzees and bonobos lived on the continent of Africa. Around that time, one group of those ancestral apes began to differentiate itself and split from the rest, becoming the hominins, Herman Pontzer, an evolutionary anthropologist at Duke University explained in his article for the Nature Education Knowledge Project. ....
My research focusses on using luminescence dating techniques to answer key questions relating to climate change and archaeology in Africa/Arabia. In particular I have worked to determine the timing and pattern of anatomically modern human (AMH) migration in present-day African and Arabian drylands. My research into North African/Arabian climate change has added to evidence that the Sahara/Arabian deserts have a long history of repeated wetting and drying, with important implications for understanding the climatic controls on future water resources and global biogeochemical cycling. Since 2010 I have focussed on understanding the timing of the evolution of “behavioural modernity” in our species. This became my main research focus in 2017 when, as one of six Principle Investigators, I established the Centre of Excellence in Early Sapiens Behaviour (SapienCE) at the University of Bergen, Norway. The SapienCE centre brings together expertise in palaeoclimatic reconstruction, archa ....
55). The primary aim was to understand the subsurface distribution of artifacts and fan deposits across the larger landscape. Artifacts are typically deeply buried within the Chitimwe Beds in all places except at the margins, where erosion has begun to remove the top part of the deposit. During informal survey, two people walked across Chitimwe Beds that appear as mapped features on Government of Malawi geological maps. As these people encountered the shoulders of Chitimwe Bed deposits, they began to walk along the margins where they could observe artifacts eroding from the deposits. By placing excavations slightly (3 to 8 m) upslope from actively eroding artifacts, excavations could reveal their in situ locations relative to their containing sediments, without the necessity of laterally extensive excavations. Test pits were emplaced so that they would be 200- to 300-m distant from the next-nearest pit and thus capture the variation across Chitimwe Bed deposits and the artifacts t ....
22 February 2021 - Wits University The NRF has re-awarded A-ratings to four Wits scientists, a grading which confirms that they are recognised as leading international scholars in their fields. The A-ratings of Professor Christopher Henshilwood, Professor Bruce Rubidge, Professor Bob Scholes, and Professor Roger Smith apply from 1 January 2021 to 31 December 2026. According to the National Research Foundation (NRF), an A-rating indicates “researchers who are unequivocally recognised by their peers as leading international scholars in their field for the high quality and impact of their recent research outputs.” Furthermore, Henshilwood and Smith, who previously held A2 ratings, are now A1-rated. A researcher in the A1 group is “recognised by all reviewers as a leading scholar in his/her field internationally for the high quality and wide impact, i.e., beyond a narrow field of specialisation, of his/her recent research outputs”, according to the NRF. ....
