Human ancestors walked comfortably upright 3.6 million years ago

A comparison of ancient and contemporary footprints reveals that our ancestors were strolling much like we do some 3.6 million years ago, a time when they were still quite comfortable spending time in trees, according to a study which will be published in the March 22 issue of the journal PLoS ONE.

When did the first 'modern' human beings appear in the Iberian Peninsula?

Research carried out by a group of archaeologists from the Centre for Prehistoric Archaeological Heritage Studies of the Universitat Autònoma de Barcelona (CEPAP_UAB) at the Cova Gran site (Lleida) has contributed to stirring up scientific debate about the appearance of the first "modern" human beings on the Iberian Peninsula and their possible bearing on the extinction of the Neanderthals.

Recently analyzed fossil was not human ancestor as claimed

A fossil that was celebrated last year as a possible "missing link" between humans and early primates is actually a forebearer of modern-day lemurs and lorises, according to two papers by scientists at The University of Texas at Austin, Duke University and the University of Chicago.

New theory on the origin of primates

A new model for primate origins is presented in Zoologica Scripta, published by the Norwegian Academy of Science and Letters and The Royal Swedish Academy of Sciences. The paper argues that the distributions of the major primate groups are correlated with Mesozoic tectonic features and that their respective ranges are congruent with each evolving locally from a widespread ancestor on the supercontinent of Pangea about 185 million years ago.

Neanderthal mind was capable of advanced thought

The widespread view of Neanderthals as cognitively inferior to early modern humans is challenged by new research from the University of Bristol published today in Proceedings of the National Academy of Sciences (PNAS) USA.

The uniqueness of humans: Robert Sapolsky class day lecture

On June 13, 2009, Robert Sapolsky--world renowned professor of neurology, neurological sciences, neurosurgery and biological sciences--gave the class day lecture in association with commencement weekend 2009. Sapolsky spoke about the uniqueness of humans in relation to the rest of the animal world, covering topics including aggression, theory of mind, the golden rule, and pleasure.

30,000-year-old teeth shed new light on human evolution

The teeth of a 30,000-year-old child are shedding new light on the evolution of modern humans, thanks to research from the University of Bristol published this week in PNAS.

Studying ancient modern humans using modern sequencing techniques

DNA that is left in the remains of long-dead plants, animals, or humans allows a direct look into the history of evolution. So far, studies of this kind on ancestral members of our own species have been hampered by scientists' inability to distinguish the ancient DNA from modern-day human DNA contamination.

Statistical analysis determines 'Hobbits' are a new human species

Researchers from Stony Brook University Medical Center in New York have confirmed that Homo floresiensis is a genuine ancient human species and not a descendant of healthy humans dwarfed by disease.

2-million-year-old evidence shows tool-making hominins inhabited grassland environments

In an article published in the open-access, peer-reviewed journal PLoS ONE on October 21, 2009, Dr Thomas Plummer of Queens College at the City University of New York, Dr Richard Potts of the Smithsonian Institution National Museum of Natural History and colleagues report the oldest archeological evidence of early human activities in a grassland environment, dating to 2 million years ago. The article highlights new research and its implications concerning the environments in which human ancestors evolved.
