Modern man found to be generally monogamous, moderately polygamous. Did women and men contribute equally to the lineage of contemporary populations?
Did our ancestors, Homo sapiens, lean more toward polygamy or monogamy? To answer these questions, Dr. Damian Labuda, an investigator at the Sainte-Justine University Hospital Research Center and a professor at the Department of Pediatrics of the Université de Montréal, headed a team that analyzed genomic data from three population samples of African, Asian and European origin. The study's findings are published in the most recent issue of the American Journal of Human Genetics. Genetic Population History In a strictly monogamous population, one would expect to have an equal number of breeding females and males and, therefore, a breeding sex ratio of one female to one male. Modern man or Homo sapiens would, therefore, usually have been monogamous while exhibiting tendencies toward polygamy over the course of evolutionary history. An innovative method of analysis. Canine Tooth Strength Provides Clues To Behavior Of Early Human Ancestors. Measuring and testing the teeth of living primates could provide a window into the behavior of the earliest human ancestors, based on their fossilized remains.
Research funded by the National Science Foundation and led by University of Arkansas anthropologist Michael Plavcan takes us one step closer to understanding the relationship between canine teeth, body size and the lives of primates. In an article published in American Journal of Physical Anthropology, Plavcan and colleague Christopher B. Stone Age Skeletons Unearthed in Libya. Archaeologists have uncovered 20 Stone-Age skeletons in and around a rock shelter in Libya's Sahara desert, according to a new study.
The skeletons date between 8,000 and 4,200 years ago, meaning the burial place was used for millennia. "It must have been a place of memory," said study co-author Mary Anne Tafuri, an archaeologist at the University of Cambridge. "People throughout time have kept it, and they have buried their people, over and over, generation after generation. " About 15 women and children were buried in the rock shelter, while five men and juveniles were buried under giant stone heaps called tumuli outside the shelter during a later period, when the region turned to desert.
The findings, which are detailed in the March issue of the Journal of Anthropological Archaeology, suggest the culture changed with the climate. Millennia of burials Tafuri and her colleague Savino di Lernia began excavating the archaeological site between 2003 and 2006. Shift in culture? Sexual Paradox: The Warrior. Chagnon (R111) Sexual Polarization in Warrior Cultures Amazon Cannibal Tribe: Men and Women speak different languages We now examine a spectrum of societies from the greater Amazon to see sexual relations in dynamic evolution, particularly in the context of warrior conflict and violence, but also in terms of partible paternity and matrilineal sexual relations and parenting.
These show interesting features relevant to understanding similar divergences between matriliny and patriliny in the emergence of urban cultures central to human history. Carol Ember (R190, R192) has calculated that 90 percent of hunter-gatherer societies are known to engage in warfare, and 64 percent wage war at least once every two years.

The hardest stereotypes to break are the ones that are so old as to go all the way back to hunter-gatherer days.
After all, how can you argue with biology? Women carry the babies, men have the upper body strength to tackle gazelles. Nobody made that up out of thin air. But if society has taught us one thing, it's that it becomes way too easy to attach amendments to that bill, claiming that all sexual and gender stereotypes date back to the early days of human evolution.
