Phylogeny Defined
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
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.
