“Human are omnivorous by evolution, morality doesn't even come into play here. As a species, criticizing us for consuming meat is as futile as calling bears or crows "immoral" for eating meat.”
No, humans have a choice and can thrive on a vegan diet. We’re eating animal products despite the lack of “necessity”. We are killing and hurting animals despite that we can live and thrive on a vegan diet.
Regardless of whether we have evolved to be able to eat animal products, doesn’t tell whether it is moral or not.
We have evolved to have the capacity to inflict unnecessary violence upon other beings e.g. humans, this doesn’t morally justify unnecessary violence.
Also the statement that we are “omnivores” is flawed. We eat animal products despite having the body of an herbivore.
Humans have evolved to eat meat and paleo-people consumed a lot of meat.
Quite the opposite is true.
Humans have no known anatomical, physiological, or genetic adaptations to meat consumption.
We have many adaptations to plant consumption.
Vitamin C is found in plants. We can’t make it ourselves such as carnivores.
