Modern Classification (Phylogeny) adds what to Linnaeus's taxonomic criteria?

• evolutionary relationships & DNA (biochemical characters)

• habitat type

• fewer categories than Linnaeus

• a naming system called binomial nomenclature

According to maximum parsimony...

• The simpler your phylogenetic tree, the better

• Phylogenetic trees should have many branches

• All organisms in a phylogenetic tree must descend from a common ancestor

• Phylogenetic trees must show all traits

​ (a)   is a branching diagram showing relationships among groups of clades while a ​ (b)   is a branching diagram that shows the inferred relationships between various species.
