Humans meet their evolutionary cousins at rendezvous points along the way, the points at which the lineage diverged.

The Fannin Sheep is a evolutionary cousin of the Dall Sheep.

A particular focus is on multiple differences in sialic acid biology between humans and our closest evolutionary cousins, the great apes.

Now it begins to look as if the platypus, if not its evolutionary cousins, the echidnas, experiences at least some of the features of REM sleep after all.

People's two closest evolutionary cousins, gorillas and chimpanzees, have evolved two very different patterns of sexual behavior and social organization.

Thus, the bivalved arthropods--the group that seemed most promising as a coherent set of evolutionary cousins--also formed an artificial category hiding an unanticipated anatomical disparity.

Or maybe you'd sleep like our close evolutionary cousin the chimp, who gets about 10 hours of sleep altogether, when you add in the afternoon nap.

Data has found a whole ship full of his evolutionary cousins.

For some reason, Mandasars found jiffpips sweet and cute... maybe because they were distant evolutionary cousins, like lemurs are to humans.
