Modern humans emerged from complex labyrinth of peoples

Re-examination of a circa 100,000-year-old archaic early human skull found 35 years ago in Northern China has revealed the surprising presence of an inner-ear formation long thought to occur only in Neandertals. “The discovery places into question a whole suite of scenarios of later Pleistocene human population dispersals and interconnections based on tracing isolated anatomical or genetic features in fragmentary fossils,” said study co-author Erik Trinkaus, PhD, a physical anthropology professor at Washington University in St. Louis. “It suggests, instead, that the later phases of human evolution were more of a labyrinth of biology and peoples than simple lines on …

Native America before European Colonization

Upon the arrival of Columbus in 1492 in the Carabean Islands, unknown to Columbus (and majority of the Eastern Hemisphere), he landed on Islands located in the middle of two huge continents now known has North America and South America that was teaming with huge Civilizations (that rivaled any in the world at that time) and thousands of smaller Nations and Tribes. With recent estimations, the population may have been over 100 million people that spanned from Alaska and Green Land, all the to the tip of southern South America.  

First Out of Africa – The totally isolated Tribe of the Andaman

There are still people in this world who have no idea that civilization exists. On remote islands in the Bay of Bengal live mysterious tribes. The five-foot high black skinned Andaman islanders are rumoured by sailors to be cannibals. Their origins are mysterious, but this film reveals how modern DNA analysis suggests that these ancient people have close links to Africa, from where they have been separated for 100,000 years

Genetics, epigenetics and disease

Royal Society GlaxoSmithKline Prize Lecture given by Professor Adrian Bird CBE FMedSci FRS on Tuesday 22 January 2013. Adrian Bird CBE FMedSci FRS is the Buchanan Chair of Genetics at the University of Edinburgh. The human genome sequence has been available for more than a decade, but its significance is still not fully understood. While most human genes have been identified, there is much to learn about the DNA signals that control them. This lecture described an unusually short DNA sequence, just two base pairs long, CG, which occurs in several chemically different forms. Defects in signalling by CG are …

Archaic Genomics – Svante Pääbo

Dr. Svante Pääbo, director of the Department of Genetics at the Max Planck Institute for Evolutionary Anthropology, has helped us understand human evolution by decoding DNA isolated from the dry bones of our ancestors. Using ancient DNA he demonstrated that Neanderthals interbred with humans when modern humans left Africa 50-80k years ago. In another study, Dr. Pääbo sequenced the DNA from a pinky bone found in a Siberian cave. Comparing this DNA to that of Neanderthal and humans his team determined this bone came from previously unknown species of hominid, now called Denisovans. Dr. Pääbo’s lecture covered these stories and …

Jahrtausende getrennte Evolution

Augenwülste, ein dominanter Kiefer, flache Stirn: Anhand bestimmter Merkmale ordnen Anthropologen Funde dem Neandertaler zu. Doch die charakteristischen Eigenschaften des prominenten Urmenschen entstanden nicht über Nacht – er hat sich aus früheren Menschenformen entwickelt. Aber wie lief diese „Neandertalisierung” ab? Neues Licht auf diese Frage werfen nun Untersuchungsergebnisse von Funden aus der sogenannten „Knochengrube” – der Sima de los Huesos in Nordspanien. Die archaischen Menschen, die hier vor etwa 430.000 Jahren lebten, besaßen demnach bereits Neandertaler typische Merkmale aber auch noch Eigenschaften früherer Menschenformen. Dies legt den Forschern zufolge nahe, dass die Entwicklung zum klassischen Neandertaler nicht kontinuierlich ablief, sondern …

What amino acids in shells can tell us about Bronze Age people

A new study by scientists at the University of York has shed new light on the use of mollusc shells as personal adornments by Bronze Age people.The research team used amino acid racemisation analysis a technique used previously mainly for dating artefacts, light microscopy, scanning electron microscopy and Raman spectroscopy, to identify the raw materials used to make beads in a complex necklace discovered at an Early Bronze Age burial site at Great Cornard in Suffolk, UK.They discovered that Bronze Age craftspeople used species like dog whelk and tusk shells, both of which were likely to have been sourced and …

Fußball-WM mit Überraschungen?

Deutsche Forscher prognostizieren einige faustdicke Überraschungen bei der Fußball-WM 2014 in Brasilien: Demnach muss England ums Weiterkommen bangen, Portugal wird es nicht ins Achtelfinale schaffen und selbst Spanien wird es schwer haben. Deutschland kommt ins Halbfinale, so die Vorhersage. Sie basiert auf Marktwert, Weltrangliste, Wettquoten und Performance in den Qualifikationsspielen. Und noch eine WM-Prognose, diesmal allerdings geht es nicht nur um den Sieger, sondern vielmehr um den Weg dahin. Den Verlauf der Fußball-WM 2014 haben Forscher der International School of Management (ISM) in Frankfurt und der Deutschen Sporthochschule Köln in einem Modell simuliert. Dafür ermittelten sie zunächst unter Einbeziehung von …

Svante Pääbo: Die Neandertaler und wir

Erstmals richtet sich der erfolgreiche Paläogenetiker Svante Pääbo an das große Publikum. Gekonnt verknüpft er seine eigene Lebensgeschichte mit einer Darstellung seiner Wissenschaft von den schwierigen Anfängen bis heute. Dabei gewährt er seltene Einblicke in den Alltag eines Spitzenforschers. Schon früh wuchs in dem schwedischen Jungen Svante Pääbo das Interesse an der Vergangenheit. Vor allem das antike Ägypten hatte es ihm angetan, seit er mit seiner Mutter das Land bereist hatte. Als er später im Medizinstudium in einem Labor das Immunsystem erforschte, begann er ohne Wissen seines Professors zu untersuchen, was an Erbinformation in antiken Überresten stecken könnte. Da er …

mtDNA of first Near Eastern farmers sequenced

The mitochondrial DNA of the first Near Eastern farmers has been sequenced for the first time. In the research, published in the journal PLOS Genetics, experts analysed samples from three sites located in the birthplace of Neolithic agricultural practices: the Middle Euphrates basin and the oasis of Damascus, located in today’s Syria and date at about 8,000 BC. The paper is signed by Daniel Turbón and Alejandro Pérez Pérez, from the Department of Animal Biology of the University of Barcelona (UB); Eva Fernández, from Liverpool John Moores University; Cristina Gamba, Eduardo Arroyo Pardo and Pedro Cuesta, from Complutense University of …
