State
Phylogeny is the evolutionary history and relationship of an organism or group, showing shared ancestry rather than degree of physical similarity.
Show
A phylogeny placing two species on branches from the same recent ancestor states their shared ancestry, independent of whether they look alike.
Watch for
Phylogenetic relationship tracks shared ancestry specifically — it does not guarantee closely related organisms will look or behave similarly.
