Direct dating of fossils

(Welles, Samuel Paul, “Paleontology,” In some cases darwinists have recognized circularity as a typical problem in evolutionary models and worked to avoid it.“To test this idea, we matched earliest Cambrian records of carbon isotope variability from Siberia, Mongolia, and China with a Moroccan record constrained by five radiometric ages from interbedded volcanic ashes.New discoveries and dating of fossil remains from the Rising Star cave system, Cradle of Humankind, South Africa, have strong implications for our understanding of Pleistocene human evolution in Africa.

Species of ancient humans and the extinct relatives of our ancestors are typically described from a limited number of fossils. More than 1,500 fossils representing at least 15 individuals of this species were unearthed from the Rising Star cave system in South Africa between 20.After the discovery was reported, a number of questions still remained. naledi had an unusual mix of ancient and modern traits. Now, Berger et al.—who include many of the researchers who were involved in the discovery of H. naledi fossils from a separate chamber in the same cave system.For example, it had a small brain like the most ancient of human-relatives, yet its wrists looked much like those of a modern human. naledi—reconsider this question in the light of new findings reported in two related studies. provide a long-anticipated estimate for the age of the fossils at between 236,000 and 335,000 years old. These estimated dates fall in a period called the late Middle Pleistocene, and mean that H.Several previous attempts to radiocarbon date the Mladeč specimens directly have failed, but in the present attempt by using teeth as dating material reliable results were obtained.The findings are now documented in a recent issue of Nature.The Mladeč samples date to around 31,000 years ago, reports Eva Maria Wild from the VERA (Vienna Environmental Research Accelerator) Laboratory at University of Vienna, where the radiocarbon dating has been performed.
