The aim of this study was to quantify fecundity, brood loss, egg mortality, and reproductive output in the
phyletic giant Damithrax spinosissimus.
In articles such as "Is a New and General Theory of Evolution Emerging" (see above) and his book Wonderful Life (Norton, 1990), Gould argued that multiple levels of selection, the phenomenon of mass extinction, and early diversification of major
phyletic groups followed by culling, all undermined the heretofore simplistic and gradualistic standard Neo-Darwinian story.
The unusual condition of the ectopterygoid and endopterygoid of Leptophilypnion may well be uniquely derived or apomorphic characters, and thus unhelpful in determining its
phyletic relationships.

This gene complex, at least as a protein-coding set of amino acids, is conserved through a wide range of forms, underlying developmental modules that can be transposed across species and even
phyletic barriers and that might even be common to vertebrates and invertebrates.

To explain this" - adds the lead author Pier [ETH]auro Ciachino, from Torino, Italy - "we must go back at least to the Late Oligocene (29-24 million years) where a continuum of land connected the Dinarides and Rhodopes mountains, allowing colonization by this
phyletic lineage.
For biology teachers, this may entail the uncertainty of finding accessible and relatively small areas in which substantial marine
phyletic biodiversity can be found.
