The acritarchs are uniformly small (< 10 [micro]m diameter), which suggests that they represent primary productivity ('algal' cysts) rather than (for example) the egg cases of
metazoans, and so the pellets can be assigned to an herbivorous
metazoan grazer, and possibly a member of the zooplankton.
Breakdown of PARP, a DNA repair enzyme that catalyses the poly (ADP-ribosyl)ation of various nuclear proteins is a hallmark of
metazoan apoptosis.
Why are they still classified as
metazoans? Is it true that they haven't evolved in millions of years?
Coupling between ice microalgal productivity and the pelagic,
metazoan food web in southeastern Hudson Bay: A synthesis of results.
Their topics include photosynthetic pigment concentrations in marine sediments, total protein flux from sediment trap samples, abundance of
metazoan meiofauna, benthic bacterial diversity based on cloning and sequencing 16S rRNA genes, and organic carbon remineralization rates in marine surface sediments.
Metazoan parasites have been reported for 19 of the approximately 60 species of Peromyscus (Hall 1981); however, except for P.
While her doctorate is in the biomedical sciences, her master's degree research was determining the molecular evolutionary relationship among lower
metazoan animals.
Thus although development had a minor role both in the work of Darwin and the establishment of the modern synthesis the developmental patterns allow understanding the branching evolutionary divergences in
metazoan and the relationship among phyla.
