While the concept has been around since the early 1970s, its interpretation in what's known as the Tool–Narayanaswamy formalism has never been experimentally measured. There's a good reason for this. Glass ages slowly in ways that can't be captured simply by watching it …Parting the foliage to disentangle the stem of our own species is not so easy. The classic out-of-Africa hypothesis suggests that Homo sapiens evolved from a distinct lineage of early human that arose around 150,000 years ago before setting off to spread through Europe and beyond. But there is another story. A genomic study led by …While the study findings may seem alarming – that blood type could change early stroke risk – let's put these results into context.
