Context for this:

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?

danc4498@lemmy.world on 19 Sep 11:25 next collapse

It ate krill

Just krill me now.

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

exasperation@lemmy.dbzer0.com on 19 Sep 20:37 collapse

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.

SuperIce@lemmy.world on 19 Sep 20:53 collapse

Eh, the giant panda isn’t the best example. It’s digestive system is still optimized for meat, which is why the need to eat a lot of bamboo and eat very specific parts of it that have a similar nutritional makeup as meat. They wouldn’t be able to survive eating other plants, but they could survive (and thrive) eating meat.

exasperation@lemmy.dbzer0.com on 20 Sep 01:59 collapse

It’s interesting because it’s very obvious, biologically, that the panda has a digestive system that has a carnivore past, and yet, the very plentiful biomass in bamboo forests just waiting to be eaten rewards the animals that can make use of it. So the giant panda may or may not be ā€œoptimizedā€ for meat, but has generations that came out of the free food that is bamboo, so that their very survival depends on a herbivore diet.

Swim away!

Revan343@lemmy.ca on 19 Sep 18:52 next collapse

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

Tollana1234567@lemmy.today on 20 Sep 08:34 collapse

Omnivorous most likely, then many animals became herbivores or carnivirous

I have thalassophobia

So do whales. Their ā€œsingingā€ is actually just them screaming in fear of the hell they’re forced to inhabit.

Someone should build a whale MRI to check your hypothesis

Hector@lemmy.world on 19 Sep 12:58 collapse

Wolves have contracted chronic wasting disease? I thought it had not spread from deer that we were aware of?

It is spreading amongst the deer it is in like half the country now including where I’m at which is one of the first place it was noticed.
