Location: Champ’s Clock Shop, Douglasville, GA Dr Rob describes a contentious idea: the Waiting Time Problem. Mathematical simulations tells us that the rise of specific new mutations would take a fantastically long time. This is a serious challenge to...
The idea that Africa was where humans originated has been drilled into our heads for decades, but cracks are beginning to appear, and they are being published by well-known scientists in top-level journals. If it is not true, how can we explain the data from a...
Location: Corkscrew Swamp Sanctuary and CREW Bird Rookery Swamp Trail, near Estero, Florida, USA We can only understand the size of DNA by comparing it to something else. If you, for example, scaled it up to the length of a major highway, how wide would it be? If you...
DNA can only withstand so much mutation and breakage before it breaks down. An amazing system of repair enzymes keeps decay in check, mostly. Yet, without the crazy complex system of DNA maintenance and repair, life cannot exist, which brings up questions of how we...
Origin-of-life research got a boost with the recent publication of a massive new computer program that was designed to model early chemical evolution. At least, that’s what the headlines say. Dr C explains that things are only getting worse for the evolutionary...
