When I was at high school, mumblety-mumble years ago, the accepted wisdom was that modern humans and Neandertals were sub-species in the same genus: Homo sapiens sapiens and H. sapiens neandertalensis. That changed, to the view that they were probably separate species, with analyses of new fossil finds. More recently, molecular biology techniques have enabled researchers to compare sapiens & […]
Continue readingI’ve just finished reading Your inner fish (Shubin, 2008) – honestly, I can’t recommend it highly enough. But for anyone who hasn’t bought the book yet, let’s look at what another part of our anatomy – our ears – has to tell us about our evolutionary past.
Continue readingAt the moment I’m reading Neil Shubin’s book Your inner fish. It’s a wonderful walk through the evolution of life, taking various aspects of our own biology & tracing their evolutionary history. Over lunch I was reading the chapter on the sense of smell, & some of the ideas there really excited me & I […]
Continue readingThere's been quite a lot of conjecture, over the years, about what our early ancestors ate. Much of the evidence has been indirect: size of teeth, size of chewing muscles (which can be estimated from measurements of the places where muscles attach to the skull), ridges & crests on the skull, & so on. Teeth […]
Continue readingWe know from fossil evidence that Neanderthals evolved in Europe around 400,000 years ago, and later (~150,000 years ago) spread into western Asia, before disappearing from all areas in their range about 30,000 years ago. However, it can sometimes be quite hard to be certain whether or not a fossil is from a Neanderthal, which […]
Continue readingLast month I asked the following question: In 2006 scientists announced the discovery of a new hominin fossil: a juvenile Australopithecus afarensis. The media quickly dubbed it "Lucy's child" (well, it was a catchy name, even though the underlying implied relationship had no evidence to support it!). So, tell me, how could scientists be sure that this individual […]
Continue readingEver since its fossil remains were discovered, scientists have wondered about the place of Orrorin tugenensis and its place in our family tree. Was it bipedal? And where were its closest relatives? One controversial suggestion was that Orrorin was directly ancestral to our own genus – leaving the australopiths completely out in the cold.
Continue readingThe other day one of my students came by my office to ask about his essay. He’d found a book that suggested that the human species was split into 3 races (black, white, & oriental, in case you’re wondering), & that these races differed in things like fecundity and birth rate. Should he include this […]
