Questions<br />
1. The results of phenetic and cladistic analysies are inherently hierarchical, as is the branching<br />
sequence of the evolution of organisms. So, too, is the Linnaean classificatory system of ever more<br />
inclusive taxonomic categories from species, Genus, Family, Order, Class, Phylum, Kingdom and<br />
Domain. Can you name some other hierarchical classification systems (not necessarily biological)<br />
2. Taxonomists were erecting classifications of organisms long before Darwin convinced<br />
biologists of the reality of evolution. Some of these taxonomists believed in the fixity of species<br />
and in special creation. Nevertheless, in some respects, these pre-Darwinian classifications are<br />
rather similar to those produced later by evolutionary taxonomists. Why do you think this is so
