Human longevity from grandmothering tied to human coupling
If you are in a special relationship with another person, thank grandma – not just yours, but all grandmothers since humans evolved. (more…)
A research team led by UA anthropologist David Raichlen has found that the Hadza tribe’s movements while foraging can be described by a mathematical pattern called a Lévy walk – a pattern that also is found in the movements of many other animals.
A mathematical pattern of movement called a Lévy walk describes the foraging behavior of animals from sharks to honey bees, and now for the first time has been shown to describe human hunter-gatherer movement as well. The study, led by University of Arizona anthropologist David Raichlen, was published on December 23, 2013 in the Proceedings of the National Academy of Sciences.
The Lévy walk pattern appears to be ubiquitous in animals, similar to the golden ratio, phi, a mathematical ratio that has been found to describe proportions in plants and animals throughout nature. (more…)
Study results could foreshadow earth’s future climate, MU researcher says
COLUMBIA, Mo. – For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University of Missouri researcher has found evidence suggesting that no ice sheet formed at this time. This finding could help environmentalists and scientists predict what the earth’s climate will be as carbon dioxide levels continue to rise.
“Currently, carbon dioxide levels are just above 400 parts per million (ppm), up approximately 120 ppm in the last 150 years and rising about 2 ppm each year,” said Ken MacLeod, a professor of geological sciences at MU. “In our study, we found that during the Late Cretaceous Period, when carbon dioxide levels were around 1,000 ppm, there were no continental ice sheets on earth. So, if carbon dioxide levels continue to rise, the earth will be ice-free once the climate comes into balance with the higher levels.” (more…)
Should climate change trigger the upsurge in heat and rainfall that scientists predict, people may face a threat just as perilous and volatile as extreme weather — each other.
Researchers from Princeton University and the University of California-Berkeley report in the journal Science that even slight spikes in temperature and precipitation have greatly increased the risk of personal violence and social upheaval throughout human history. Projected onto an Earth that is expected to warm by 2 degrees Celsius by 2050, the authors suggest that more human conflict is a likely outcome of climate change. (more…)
Part of the 4Afrika Initiative, the program will offer mentorship, training, university-level education and employment opportunities to aspiring African youth.
LAGOS, Nigeria — Aug. 12, 2013 — In recognition of International Youth Day, Microsoft Corp. Monday introduced the 4Afrika Scholarship program, as part of its 4Afrika Initiative, through which it will provide mentorship, leadership and technical training, certification, university-level education, and employment opportunities for promising African students. Mentorship will be provided by Microsoft employees from around the world, and employment opportunities will include internships and both part-time and full-time jobs within Microsoft, as well as with the company’s more than 10,000 partners across Africa.
Through the company’s 4Afrika Initiative and YouthSpark program, Microsoft has committed to helping millions of Africans get critical skills for entrepreneurship and employability. The 4Afrika Scholarship program is one way the company intends to meet that goal, by helping ensure that promising youth have access to the education, resources and skills they need to succeed, regardless of their financial situations. To help redress gender disparity in higher education in Africa, the company is actively encouraging young women to apply. (more…)
UD professor, scholar document culture of Peruvian community
As the elders of a small hunter-gatherer community told the story of how their people came to be, University of Delaware assistant professor of art Jonathan Cox and Summer Scholar Sarah Driver sat and listened, intrigued by the tale.
Over the course of seven days, they learned firsthand about the Ese’eja (ess-a-eha) Nation, a community of three distinct villages living in the remote areas of Infierno, Palma Real and Sonene, Peru. (more…)
People in most cultures view women with small feet as attractive. Like smooth skin or an hourglass figure, petite feet signal a potential mate’s youth and fertility.
Because they signal reproductive potential, a preference for mates with these qualities may have evolved in the brains of our Pleistocene ancestors and are viewed by evolutionary psychologists as evidence that the preference is hard-wired into our genetic makeup. (more…)
In January, 60 young Tanzanian children began attending school for the first time, thanks to a project led by Michigan State University.
MSU and its partners in the Tanzanian Partnership Program built a new school on 100 acres donated by two village elders in a sub-village of Milola known as Ngwenya. Construction funds were provided by the TAG Philanthropic Foundation, based in New York. (more…)
