In this project I examine the influence of information about competence on contributions in online social dilemmas. In any real world situation, individuals will vary in terms of their competence, where competence is defined as having sufficient knowledge or skills to act effectively in a given context. Once we challenge the assumption that all individuals are fully and equally competent, perceptions of competence become essential influences to behavior in social dilemma situations. Precisely how perceptions of competence figure into decisions to contribute or free-ride has largely been neglected as a topic of study, however. Judd Antin - Research
Asian Neanderthals, Humans Mated - The oldest modern human remains from East Asia have been found and date to at least 100,000 years ago. - The structure of the fossils and age all suggest that modern humans interbred with Neanderthals. - The findings also reveal that modern humans were established in East Asia much earlier than in Europe. Early modern humans mated with Neanderthals and possibly other archaic hominid species from Asia at least 100,000 years ago, according to a new study that describes human remains from that period in South China. The remains are the oldest modern human fossils in East Asia and predate, by over 60,000 years, the oldest previously known modern human remains in the region.
Neanderthal gene found in human DNA of people living out of Africa - Times Online
Neanderthals, Humans Interbred, DNA Proves - A newly mapped Neanderthal genome provides strong evidence that humans and Neanderthals interbred. - Between 1-4 percent of the DNA of many humans living today likely came from Neanderthals. - People of European and Asian heritage are most likely to carry the Neanderthal genes. It's official: Most of us are part Neanderthal.
Toba catastrophe theory The Toba supereruption was a supervolcanic eruption that occurred some time between 69,000 and 77,000 years ago at the site of present-day Lake Toba (Sumatra, Indonesia). It is one of the Earth's largest known eruptions. The Toba catastrophe hypothesis holds that this event caused a global volcanic winter of 6–10 years and possibly a 1,000-year-long cooling episode. The Toba event is the most closely studied super-eruption. In 1993, science journalist Ann Gibbons suggested a link between the eruption and a bottleneck in human evolution, and Michael R. Rampino of New York University and Stephen Self of the University of Hawaii at Manoa gave support to the idea.
National Geographic Adventure Mag: Genographic, Spencer Wells Spencer Wells is risking life and limb to collect DNA from the most isolated, remote peoples on the planet. Five years, 100,000 samples, and 40 million dollars later, he'll have a new road map to human history. By Michael Shnayerson Spencer Wells knows exactly where he wants to go next: the Tibesti mountains. He wants to fly to Libya, now that it's open to Westerners again, then hail a camel caravan across the Libyan desert to Chad, where the seven inactive volcanoes of the Tibesti rise 11,000 feet (3,353 meters) from the central Sahara: a private world of crags and chasms seldom seen by more than a handful of outsiders.
Evolution of Modern Humans: Early Modern Homo sapiens Early Modern Homo sapiens All people today are classified as Homo sapiens. Our species of humans first began to evolve nearly 200,000 years ago in association with technologies not unlike those of the early Neandertals. It is now clear that early Homo sapiens, or modern humans, did not come after the Neandertals but were their contemporaries. However, it is likely that both modern humans and Neandertals descended from Homo heidelbergensis.
