Which of the following is an advantage of phylogenetic classification?

it forces organisms into specific taxonomic groups

it produces a continuous tree without forcing organisms into ill-fitting groups

it allows for overlap between the groups produced

it is based solely on visible features of organisms

In a phylogenetic tree, the relative positions of branching points show:

the lifespan of each species

the geographical location of species

the size of each species population

the distance of shared common ancestors

Artificial classification groups organisms based on:

behavioural analyses

developmental studies

molecular comparisons

differences that are useful at the time, such as colour, size, number of legs, leaf shape, etc.
