Vanessa Hayes, University of Sydney Where was the evolutionary birthplace of modern humans? The East African Great Rift Valley has long been the favoured contender – until today. Our new research has used DNA to trace humanity’s earliest footsteps to a prehistoric wetland called Makgadikgadi-Okavango, south of the Great Zambezi River. Our analysis, published in […]
Sleep. We all need it, and most of us don’t get enough of it. And even if we get the average recommended amount (the good old 8-hour dosage), that takes up about a third of our lives overall. But why do we sleep, from an evolutionary standpoint? The fact that it’s so widespread in the […]

The environmental impact of cigarettes is well documented: For more than 30 years, cigarette butts have been the most collected type of beach litter. Cigarette butts also account for approximately 38% of litter items globally and can take about a decade to biodegrade.
Typically, environmental causes are associated with left-leaning politics, and pro-military action is publicly associated with the right. However, a large number of veterans are liberals or are willing to embrace bipartisanship when it comes to sustainability. Thus, some veterans are speaking up about environmental damage.
Wildlife crossings over (and under) the highways could make animals (both wild and domesticated) and people safer. Our expanding network of roads are interrupting and fragmenting the territories of wild (and also domesticated) animals who need to cross our roads in search of food, water, mates, and shelter. Many are routinely struck and killed by […]
By Connie Benton It’s easy to see the benefits of going green if you love nature. But what if you couldn’t care less about the whales, the sea turtles, and whatever species the activists want to save next? There are still plenty of reasons for you to make your office eco-friendly. Here are five of […]
Walking on two legs is an evolutionary leap that led humans to conquer the world. But, why humans are walking on two legs? It’s still unclear. Now, according to a new study published on the University of Chicago’s Journal of Geology, the reason might be exploding stars a few million years ago.
