Human Evolution Is Speeding Up
Eric wu submitted, created time 1 year 4 weeks (sciencenow.sciencemag.org)
Plentiful food has made it easier than ever before to survive and reproduce in many parts of the world, so it's tempting to think that our species has stopped evolving. But a controversial new study says that isn't so. Far from slowing down, human evolution has sped up in the past 40,000 years and has become 100 times faster in the past 5000 years alone, according to the analysis. This means that even though some people have been globe-trotters who interbreed, most humans on different continents are becoming more different, rather than blending together into one genetically homogenous race. 
Culture Speeds Up Human Evolution

Homo sapiens sapiens has spread across the globe and increased vastly in numbers over the past 50,000 years or so—from an estimated five million in 9000 B.C. to roughly 6.5 billion today. More people means more opportunity for mutations to creep into the basic human genome and new research confirms that in the past 10,000 years a host of changes to everything from digestion to bones has been taking place.
The article tell us the history of human evolution with the development of culture. In other word, human evolution affect by the nature and society culture.
On the evolutionary origin of aging
wugongliang submitted, created time 1 year 3 months (www.blackwell-synergy.com)
It is generally believed that the first organisms did not age, and that aging thus evolved at some point in the history of life. When and why this transition occurred is a fundamental question in evolutionary biology.
Human-Like Altruism Shown In Chimpanzees
gh0706 submitted, created time 1 year 6 months (www.medicalnewstoday.com)
Debates about altruism are often based on the assumption that it is either unique to humans or else the human version differs from that of other animals in important ways. Thus, only humans are supposed to act on behalf of others, even toward genetically unrelated individuals, without personal gain, at a cost to themselves. Studies investigating such behaviors in nonhuman primates, especially our close relative the chimpanzee, form an important contribution to this debate
Paternity discrepancy -- society, trust and possible evolutionary basis
Darkfrog submitted, created time 1 year 8 months (men.msn.com)
This is a little less reputable than I usually prefer to post. It is mostly about social roles and trust issues, but it does address the evolutionary aspects of fatherhood. Mostly, I've just never heard of "paternity discrepancy" before. It refers to the phenomenon of a man raising a child that is not, despite his beliefs to the contrary, his genetic offspring. (Knowing adoptive fathers and stepfathers do not apply.)

Ancestral Alleles and Population Origins: Inferences Depend on Mutation Rate
fiona submitted, created time 1 year 8 months (mbe.oxfordjournals.org)
"Previous studies have found that at most human loci, ancestral alleles are "African," in the sense that they reach their highest frequency there. Conventional wisdom holds that this reflects a recent African origin of modern humans. "
