To read the rest, click on "Selective Extinctions Defy Logic".To believe the standard evolutionary timeline, you have to accept some highly unreasonable notions.Museums and nature TV shows routinely show the march of evolution through time. The story is punctuated by several major extinction events, the most famous of which is the death of the dinosaurs at the end of the Cretaceous. The current popular theory is that an asteroid slammed into earth, causing the death of all the dinosaurs, pterosaurs and marine reptiles in a geological instant (called the KPg boundary). Do viewers ever ponder the fact that many delicate animals lived right through this catastrophe as if nothing happened?Genomic evidence reveals a radiation of placental mammals uninterrupted by the KPg boundary (PNAS). The early placental mammals (a group that includes us humans) were believed to be rather small, perhaps badger size, at the time of the extinction. They were no match for T Rex and Triceratops. Why, then, did they survive “uninterrupted” right through the disastrous extinction event? This group of evolutionary scientists, using different assumptions for dating ‘divergence times’ (when mammal groups supposedly branched into different families), believes that’s exactly what happened.
