The researchers argue that the DNH 155 specimen they found provides the first high resolution evidence for microevolution within an early hominin species. In 1938, Robert Broom discovered the first Paranthropus robustus material at the site of Swartkrans, South Africa. The skull of a two million-year-old distant cousin of humans has been uncovered by an Australian research team in South Africa. "We believe these changes took place during a time when South Africa was drying out, leading to the extinction of a number of contemporaneous mammal species. Important specimens: Paranthropus robustus SK 23 – a lower jaw discovered in Swartkrans, South Africa "It is likely that climate change produced environmental stressors that drove evolution within Paranthropus robustus.". Last modified on Tue 10 Nov 2020 08.10 EST. The almost complete male skull, found in the Drimolen cave system near Johannesburg in 2018, may also lead to a new understanding of human microevolution. But a new fossil discovery in South Africa suggests that P. robustus evolved rapidly during a turbulent period of local climate change about 2 million years ago, resulting in anatomical changes that previously were attributed to differences between the sexes. Findings from the new discovery in South Africa’s Cradle of Humankind were published in Nature Ecology and Evolution on Tuesday. Die Körperform der Art ähnelt derjenigen von Australopithecus africanus, jedoch besaß Paranthropus robustus einen größeren, kräftigeren Schädel sowie massivere Zähne und wird daher gelegentlich auch robuster Australopithecus genannt. Paranthropus " derives from Ancient Greek παρα para beside or alongside; and άνθρωπος ánthropos man. Paranthropus ist eine fossile Gattung der Hominini in der Familie der Menschenaffen (Hominidae). It is likely that climate change produced environmental stressors that drove evolution within Paranthropus robustus.”. … This rare male fossil is closer in size to female specimens previously found at the site, providing the first high-resolution evidence for microevolution within early hominin species. It has been identified in Kromdraai, Swartkrans, Sterkfontein, Gondolin, Cooper's, and Drimolen Caves. Broom's work on the australopithecines showed that the evolution trail leading to Homo sapiens was not just a straight line in the evolutinary tree, but was one of rich diversity. The fossil was a male … By. Washburn and Patterson, 1951. The Genus Paranthropus includes the species boisei, and robustus. Louis & Mary Leakey are credited with the discovery of Australopithecus (now known as) Paranthropus boisei. As such the skull discovery presented a rare example of "microevolution" within human lineage, Mr Martin said. Dental studies suggest the average Paranthropus robustus rarely lived past 17 years of age. As a potential “cousin species” to Homo erectus, it has long been thought that that the Paranthropus robustus died out earlier, having struggled to survive. Paranthropus robustus walked the earth at roughly the same time as our direct ancestor Homo erectus, Tue 10 Nov 2020 05.22 EST True. Archaeologist Andy Herries said the skull, which was painstakingly reconstructed from hundreds of bone pieces, represented the start of a very successful Paranthropus robustus lineage that existed in South Africa for a million years. Molar characteristics from the more recent material from the Drimolen site are thought to be intermediate between the Swartkrans and Kromdraai molars, and most researchers now c… Australopithecus robustus. The archaeologist Andy Herries said the skull, which was painstakingly reconstructed from hundreds of bone pieces, represents the start of a very successful Paranthropus robustus lineage that existed in South Africa for a million years. "But these two vastly different species — Homo erectus with their relatively large brains and small teeth, and Paranthropus robustus with their relatively large teeth and small brains — represent divergent evolutionary experiments," she said. But a new fossil discovery in South Africa instead suggests that P. robustus evolved rapidly during a turbulent period of local climate change […] The well-preserved fossil is believed to be the earliest known example of the Paranthropus robustus, according to the research team from Melbourne's La … Paranthropus robustus is a species of robust australopithecine from the Early and possibly Middle Pleistocene of the Cradle of Humankind, South Africa, about 2 to 1 or 0.6 million years ago. Paranthropus robustus was a large-toothed, small-brained hominin that co-existed with our early direct human ancestors as a ‘cousin species’. Available for everyone, funded by readers. “Like all other creatures on earth, to remain successful our ancestors adapted and evolved in accordance with the landscape and environment around them,” he said. The male from Drimolen had features that were most similar to the female from Drimolen, disproving the long-held belief that Paranthropus robustus were most like gorillas. The cranium represents a young adult male, and dates to approximately 2.0-1.5 Ma. Males of the extinct human species Paranthropus robustus were thought to be substantially larger than females — much like the size differences seen in modern-day primates such as gorillas, orangutans and baboons. However, laser ablation stable isotope analysis reveals that the δ13C values of Paranthropus robustus individuals often changed seasonally and interannually. “While we were the lineage that won out in the end, two million years ago the fossil record suggests that Paranthropus robustus was much more common than Homo erectus on the landscape.”. Paranthropus boisei, arguably the best known of the robust australopithecines, (the species included in the genus Paranthropus—Paranthropus aethiopicus, Paranthropus robustus, and Paranthropus boisei) is known from East African sites dating between 2.4 and 1.4 million years ago The first fossils of this species were uncovered in 1955, but Paranthropus boisei was not officially declared a new. Donald Johanson is credited with the discovery of Australopithecus afarenisis. Key points: Paranthropus robustus walked the Earth at roughly the same time as Homo erectus The fossil discovery provides the first high-resolution evidence for microevolution within early hominin species The skull was painstakingly reconstructed from hundreds of bone pieces "While we were the lineage that won out in the end, two million years ago the fossil record suggests that Paranthropus robustus was much more common than Homo erectus on the landscape.". A press release by Washington University in St. Louis reports that a student discovered the paradigm-shifting Paranthropus robustus skull during a field school dig at “the fossil-rich Drimolen cave system northwest of Johannesburg” in South Africa. This rare male fossil is closer in size to female specimens previously found at the site, providing the first high-resolution evidence for microevolution within early hominin species. Since then, more than 300 Paranthropus fossils have been uncovered and three species are now included in the group. "Like all other creatures on Earth, to remain successful our ancestors adapted and evolved in accordance with the landscape and environment around them," he said.
