Gendered division of labor gave modern humans advantage over Neanderthals

12-04-2006 · EurekAlert!

Diversified social roles for men, women and children may have given Homo sapiens an advantage over Neanderthals, says a new study in the December 2006 issue of Current Anthropology. The study argues that division of economic labor by sex and age emerged relatively recently in human evolutionary history and facilitated the spread of modern humans throughout Eurasia.

  1. Stone Age Role Revolution: Modern humans may have divided labor to conquer
    12-02-2006 · Science News Online
    A new analysis of Stone Age sites indicates that a division of labor first emerged in modern-human groups living in the African tropics around 40,000 years ago, providing our ancestors with a social advantage over Neandertals.

  2. Genetic study of Neanderthal DNA reveals early split between humans and Neanderthals
    11-15-2006 · EurekAlert!
    In the most thorough study to date of the Neanderthal genome, scientists suggest an early human-Neanderthal split. The two species have a common ancestry, say the authors, but do not share much else after evolving their separate ways. The study, published in this week's issue of Science, also finds no evidence of genetic admixture between Neanderthals and humans.

  3. The ESRF reveals how Neanderthal teeth grew
    11-24-2006 · EurekAlert!
    Scientists from the United Kingdom, France and Italy have studied teeth from Neanderthals with X-rays from the European Synchrotron Radiation Facility (ESRF). They found that the dental development of Neanderthals is very similar to modern humans.

  4. Extinction of Neanderthals Was Not a Climate Disaster Scenario
    09-26-2007 · Woods Hole Oceanographic Institution (WHOI)
    Scientists have offered several competing theories for what led to the extinction of the Neanderthals, with much of the debate focusing on the relative roles of climate change versus conflict with modern humans. New research shows that Neanderthals did not die out at a time of extreme and sudden climatic change, as some researchers have suggested.

    454 Life Sciences today announced that comparison of the human and chimpanzee genomes to Neandertal DNA sequences determined by 454 Sequencing reveals that modern human and Neandertal DNA sequences diverged on average about 500,000 years ago and the effective size of the ancestral population of the two groups was similar to that of modern humans.

  6. Prehistoric origins of stomach ulcers uncovered
    02-07-2007 · EurekAlert!
    Scientists have discovered that the ubiquitous bacteria that causes most painful stomach ulcers has been present in the human digestive system since modern man migrated from Africa over 60,000 years ago. They compared DNA sequence patterns of humans and the Helicobacter pylori bacteria now known to cause most stomach ulcers and found that the genetic differences between human populations that arose as they dispersed from Eastern Africa over thousands of years are mirrored in H.pylori.

  7. Fossil shows human growth at least 160,000 years ago
    03-13-2007 · EurekAlert!
    An international team of scientists have found that the oldest member (160,000 years old) of the genus Homo shows a modern human life history profile. These findings, based on experiments at ESRF, are in contrast to previous studies suggesting that early fossil humans possessed short growth periods, which were more similar to chimpanzees than to living humans.

  8. Researchers find earliest evidence for modern human behavior in South Africa
    10-17-2007 · EurekAlert!
    Evidence of early humans living on the coast in South Africa, harvesting food from the sea, employing complex bladelet tools and using red pigments in symbolic behavior 164,000 years ago, far earlier than previously documented, is being reported in the Oct. 18 issue of the journal Nature. The international team of researchers reporting the findings include Curtis Marean, a paleoanthropologist with the Institute of Human Origins at Arizona State University.

  9. More human-Neandertal mixing evidence uncovered
    11-02-2006 · EurekAlert!
    A reexamination of ancient human bones from Romania reveals more evidence that humans and Neandertals interbred. Erik Trinkaus, Ph.D., Washington University Mary Tileston Hemenway Professor in Arts & Sciences, and colleagues radiocarbon-dated and analyzed the shapes of human bones from Romania's Petera Muierii (Cave of the Old Woman). The fossils, discovered in 1952, add to the small number of early modern human remains from Europe known to be more than 28,000 years old.
