I’m going to talk about one or two peer reviewed papers, but in doing so, I’m going to have to say a few words … and this will not be pretty … about a certain science writer’s report at the BBC. In an article titled “Space is the final frontier for evolution, study claims” BBC…

Spoor of South African Dinos Analyzed

A new investigation of the sedimentology and ichnology of the Early Jurassic Moyeni tracksite in Lesotho, southern Africa has yielded new insights into the behavior and locomotor dynamics of early dinosaurs.

The evolutionary history of mammals can be reviewed as the evolutionary history of tooth loss. The early mammals had many teeth, and every now and then in evolutionary time, a tooth is lost wiht subsequent species arriving from that n-1 toothed form having that smaller number of teeth. With ver few exceptions, no mammals have…
