RE: couldn't early human evelution be used to argue againist veganism
It is true that humans have much longer digestive tracts than dedicated carnivores, which is more in keeping with more herbivorous diets. A counterexample is the giant panda, whose digestive tract is hopelessly short for a herbivore.

From a health perspective, where you get your nutrients isn't important, only that you get enough of what you need and in appropriate amounts. Vegans have a much harder time of it, but it's hardly impossible. Consider that whatever we get from meat, the animal got from its own food sources. Granted, they may be adept at extracting such nutrients from sources we cannot, but it means the sources are there.

Some cultures actually do get by on vegan diets. Point of interest: people on vegan diets in developing countries tend to be (when corrected for other influences) healthier than their vegan counterparts in the west. The reason appears to be that their food contains substantially more insect fragments.

If there is no bigger meaning, then the smallest act of kindness is the greatest thing in the world.

Every world spins in pain. If there is any kind of supreme being, it is up to all of us to become his moral superior.

Um, no - it doesn't work that way.
What we get from animals is not what they ate, but what they synthesized.

Skepticism is not a position; it is an approach to claims.

Here's a tip. You won't get far if you use that as an advertising slogan.

Atheism is NOT a Religion. It's A Personal Relationship With Reality!

No

What you have made is a naturalistic fallacy.

It's like using the fact that our ancestors usually live to thirty as an argument against medicine.

Do you know what they are synthesising that we are not? Their biology is not that different. The essential amino acids vary from species to species (the ones that cannot be synthesised by that organism), and we are one of the few organisms on the planet that can't make our own vitamin C (not that we turn to bacon and eggs to keep us in supply anyway), but the real producers for are nutritional requirements are plants. Only autotrophs like plants can generate carbohydrates and amino acids and so forth from inorganic substrate. Heterotrophs like fungi and animals have to acquire organic nutrients by taking them from the forms, waste, and/or secretions of other organisms.
