Origins Of The...
DNA tests on Origin of the Species author Charles Darwin's great grandson have revealed that the founder of evolution evolved from the first group of Homo sapiens to leave Africa.
"Charles Darwin's ancient ancestors were among the first group of Homo sapiens to leave Africa, a DNA analysis has revealed. His forebears, Cro-Magnon men, left Africa about 45,000 years ago, heading to the Middle East and Central Asia, then migrated to Europe about 10,000 years later. There, they clashed with the Neanderthals, driving them to extinction. During the last Ice Age they retreated to Spain before moving north again about 12,000 years ago. Darwin's ancient family history was revealed by DNA tests on his great-great-grandson, Chris, who lives in the Blue Mountains, just west of Sydney. Chris Darwin's Y chromosome was analysed as part of the Genographic Project, which is tracking the migratory history of humans. It shows he belongs to a male lineage called Haplogroup R1b. Mr Darwin, 48, who emigrated to Australia in 1986, said yesterday that he had been intrigued to discover that his ancestors had been in one of the first groups of H. sapiens to leave Africa. 'I have always clung to the hope that I had inherited Charles Darwin's adventurous ability, his wish to go over the hill and see what's on the other side. From what I hear of my background, it sounds like we like looking over the tops of hills.' Mr Darwin has already demonstrated his intrepid spirit, windsurfing around Britain and hosting the 'World's Highest Dinner Party' at 2,200 feet, on the summit of Peru's highest mountain, Huascaran – an event marred only by the red wine freezing and two guests suffering hypothermia."
These five main food groups are important for your brain's health and likely to boost the production of feel-good chemicals.
We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.
Infographics show the classes and anxieties in the supposedly classless U.S. economy.
For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
