Hybrider Wohlfahrtskorporatismusfore are serially dependent upon some single, ultimate cause with clocklike behavior. This hypothesis is controversal, in part because of questions regarding the identity and timing of certain extinction events and because of speculations concerning possible catastrophic extraterrestrial forcing mec

Anagenetic characteristics, such as loss of bithecae and reduction of first order stipes (progressive atrophies from quadriradiate, through triradiate to biradiate organizational schemes) are achieved polyphyletical

Hybrider Wohlfahrtskorporatismushanisms. New data on extinctions of marine animal genera are presented that display a high degree of periodicity in the Mesozoic and Cenozoic as well as a suggestion of nonstationary periodicity in the late Paleozoic. However, no periodicity is evident among the as yet poorly documented extinction events of the early and middle Paleozoic.
