Current Events > Why do omnivores exist?

(+) Yeah! (+)

I get that herbivores evolved due to their being plants on earth and therefore their diets became dependent on those plants and that carnivores evolved due to herbivores and therefore their diet became dependent on those herbivores. But where did the line split and omnivores came to be?

Theyre very indecisive

Being able to get energy from both plants and meats sound like an evolutionary advantage to me. Does it not?

According to Wiki...

Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms (Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla).[8][9][10] Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears.[11][12]
The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. Frugivores include maned wolves and orangutans;[13][14] insectivores include swallows and pink fairy armadillos;[15][16] granivores include large ground finches and mice.
All of these animals are omnivores, yet still fall into special niches in terms of feeding behavior and preferred foods. Being omnivores gives these animals more food security in stressful times or makes possible living in less consistent environments.[17]

Too bad we're really bad at it.
