A skeleton discovered by a nine-year-old boy near Johannesburg in South Africa is being hailed as one of the most important finds in human archaeology. It is argued the skeleton provides the possible missing link between ape men and the human family and is said by experts to be the most complete skeleton of a human being ever discovered. It has not ended the debate however on how the species evolved. Some scientists argue, “Homo erectus” may have evolved before the skeleton from South Africa’ (29 September 2011).
In TIME, Michael Lemonick says that “[e]volution skeptics [also known as Creationists] like to trot out the argument that if Darwin had been right, scientists would have discovered transitional fossils by now — creatures with a mix of features from earlier and later species. Since they haven’t, the deniers say, evolution must not be true. The truth is that paleontologists have found transitional species by the score, from many different time periods. But none have materialized from as crucial a point in our evolutionary past as a pair of skeletons whose discovery was announced [on 10 April 2010] by the journal Science. The fossils, which have been determined to be of a new species, Australopithecus sediba, were found by Matthew Berger, the 9-year-old son of paleontologist Lee Berger, of South Africa’s University of the Witwatersrand. (The elder Berger tried in vain to get the editors of Science to list Matthew as a co-author of the paper.) The bones belong to a preteenage boy and a woman estimated to have been in her late 20s or early 30s; the individuals died at about the same time, and before their remains had fully decomposed, they were entombed in an avalanche of sediment and were nearly perfectly preserved deep in the Malapa cave north of Johannesburg”.
In Science, however, we can read that ‘[n]ewly exposed cave sediments at the Malapa site include a flowstone layer capping the sedimentary unit containing the Australopithecus sediba fossils. Uranium-lead dating of the flowstone, combined with paleomagnetic and stratigraphic analysis of the flowstone and underlying sediments, provides a tightly constrained date of 1.977 ± 0.002 million years ago (Ma) for these fossils. This refined dating suggests that Au. sediba from Malapa predates the earliest uncontested evidence for Homo in Africa’. And just to make sure nobody missed the point of the quote, here is the salient final sentence once again: the Australopithecus sediba remains “predate the earliest uncontested evidence for Homo in Africa”.
A team led by Professor Lee Berger, a renowned palaeoanthropologist, have described and named a new species of hominid, Australopithecus sediba, almost two million years old, which was discovered in the Cradle of Humankind World Heritage Site, 40 kilometres out of Johannesburg, South Africa.
