PHYLOGENY
The evolution of a organism depends on what type of organism it is

If by biological you mean the phylogeny it's phylum mollusca, class bivalvia, subclass heterodonta
Phylogeny
A phylogeny is history of organisms and they have six kingdoms.
answer difference between ontogeny and phylogeny?
Kingdom and phylogeny are related because they both have to do with facts about the organism.
The oldest use for phylogenies of genes is inferring organismal phylogeny (Fitch, 1996)
Molecular analysis supports much of the original phylogeny and helps to clarify certain relationships.
