This is just a small update on the issue of gradualism and the palaeontological record that I started in 2013. There I suggested that in a number of iconic species (chosen more or less at my whim, in fact) the fossil pattern shows a significant number of specimens of a small number of species, suggesting a stasis-saltation pattern rather than the expectations from the classic gradualism pattern of evolution, which would give a large number of species with very few representatives of each.
