Comment on Natural selection at work

The common ancestor that links whales and deer existed millions of years ago and exhibited features shared by both groups. This ancestor likely possessed basic artiodactyl characteristics, such as an even number of toes on each foot and a certain bone structure within the ear. Over time, as these creatures diverged to inhabit distinct environments, their physical traits adapted accordingly. Despite these differences, the underlying genetic similarities persist, revealing their deep-rooted connection.

Was the common ancestor carnivorous or herbivorous?

Almost all herbivores are opportunistic carnivores; deer eat birds. Presumably some great swimmers thought the krill (or some other sea life) represented a great opportunity

Weird to think that deer descended from krill eaters. Maybe that’s why they love salt licks so much.

I remember reading that the common ancestors of all birds was carnivorous. Basically every herbivore bird descended from carnivores.
See also the giant panda and the red panda.

Omnivorous most likely, then many animals became herbivores or carnivirous
