In this study we show that the most taxonomically diverse clades in the modern ocean have risen to dominance through greater resistance to extinction rather than via greater propensity to generate new species.

In this paper, we develop a framework for explicitly separating the influence of extinction intensity and extinction selectivity on causing overall changes in the composition of the biota.

We find that smaller-bodied marine animals are generally at higher risk of extinction during most of geological time. This finding holds even after demonstrating and accounting for the lower sampling completeness of the fossil record for smaller genera.
