University of Colorado at Boulder researchers who conducted a chemical analysis of australopithecine fossils ranging between roughly 1.8 million and 2.2 million years old from two South African caves found that teeth thought to belong to females are more likely to have incorporated minerals from a distant region during formation than those from males. This leads researchers to believe that the females joined new social groups once they reached maturity.
From Nature News:
Fossilized teeth of early human ancestors bear signs that females left their families when they came of age, whereas males stayed close to home.
A chemical analysis of australopithecine fossils ranging between roughly 1.8 million and 2.2 million years old from two South African caves finds that teeth thought to belong to females are more likely to have incorporated minerals from a distant region during formation than those from males.
The shape of ancient human families has been the subject of speculation, based mainly on differences in the relative size of male and female fossils, and the behavioural patterns of our primate relatives. Female chimpanzees, for instance, typically leave their social group once they hit maturity. Among gorilla groups, which are dominated by one large male 'silverback', both males and females tend to strike out.
Modern humans, who are influenced by relatively recent cultural practices such as marriage and property ownership, are difficult to compare to our early ancestors, lead author Sandi Copeland of the University of Colorado at Boulder said in a press briefing.

Not often do we stop and look back at all that has been accomplished by and for women in the past 100 years. But yesterday, on the 100th anniversary of International Women’s Day, we and our network partners had a chance to reflect, celebrate, and reinvigorate our determination to advance equality and equal opportunity.
I took the helm at The White House Project at an interesting moment for women. Last week’s report from the White House, which Kate Meyer mentioned in yesterday’s post, coupled with a political, economic and social environment that is best described as extremely volatile across the globe, demonstrates how, on this International Women’s Day 2011, we are presented with a unique opportunity.
Feminism shouldn't be exclusive to scholars, advocates, researchers and policy wonks. Women's issues affect all of us, and this is an excellent way to introduce knowledge to the general public, who, if given the facts, might understand, care and perhaps be moved to action. Kudos to video director, Sam Taylor-Wood, Dame Judi Dench, and the ever appealing Daniel Craig for the direct approach, straight talk, and for using their star power to deliver a meaningful message to the masses.
Passionate Politics: The Life & Work of Charlotte Bunch
A New One-Hour Documentary by Tami Gold
This new film tells the story of Charlotte Bunch, from idealistic young civil rights organizer to lesbian activist, to internationally-recognized leaders of a campaign to put women's rights on the global human rights agenda. Charlotte has been both a product and creator of her times: every chapter in her life is a chapter in the story of the modern feminist activism, from its roots in the 1960s struggles for social justice to international campaigns against gender-based violence today.
