| Summary: | If species selection shapes the history of clades, we should be able to detect its impact within well-established monophyletic descent groups. We should find that high rates of speciation/extinction are heritable. Demonstrating that high speciation/extinction rates have not been transmitted along known lines of descent would prove that species selection had not played an important role with the descent group under study. I have screened speciation rates within the Cenozoic planktonic foraminifera for heritability. Neither modified parent-offspring tests nor rank concordance tests reveal inheritance of this trait. |
