I feel like in every discussion i have with a meat eater i can always beat their arguments with facts, but when i say we are biologically meant to eat plants they always say that eating meat was an important and natural step in our evolution and made our brains grow etc... I can never argue back when they say this. Can anyone help? maybe link a study about this or something? it would be appreciated

This is a false dichotomy. We are frugivores biologically so you are right, but they are also right because meat played an important part in the evolution of our large brains. For most of our evolutionary history we did not eat very much meat. We ate like chimpanzees and bonobos do today....mostly fruit, with some insects and small animals when they could be caught. A lot of meat in the diet is a more recent development of our homonid ancestors, but our overall anatomy is still that of a frugivore.

ETA: With the advent of dietary supplements, we have the option to not exploit animals. To continue to use them when it isn't necessary is to needlessly kill animals, which is immoral. For them to say that it is moral, or that we 'should' because it was an important part of our development as a species, is a non-sequitur. Breast milk/infant formula is an important part of our development as individuals but that doesn't mean we should consume it into adulthood. Similarly, the role that meat played in our development as a large brained species doesn't mean we should consume it today. Our brains are already as big as they are going to get. The next step in our evolution will probably be some transhumanistic merging of biology and technology such as the introduction of nanobots into our bloodstream and brains that will give us instant access to information without having to use a computer or other device, ala Ray Kurzweil et al.

That is irrelevant to the questionof whether we should eat meat now.

Also, as far as I understand it, eating meat was allegedly advantageous at some past time because it enabled us to get calories faster than gathering nuts and berries or whatever, not because meat was fundamentally more nutritous.

I would say killing animals was an understandable decision in those days but nowadays since we can easily get all the calories and nutrients we need from plant foods, that is no longer relevant to the question of whether we need to eat meat today.

Yes it's something I've researched because I have a science degree and am seeking a second one (and also because of my cultural sensitivity to native tribes like the Yurok who revere the salmon for allowing their people to survive 7000 years, though the rest of their diet was mainly nuts, berries, greens and teas they do eat fish which they caught sustainably).

1) What caused us to evolve was fire, not meat. Apes are currently close to discovering how to build a fire and researchers are wondering if we will see them evolve right before our very eyes. Fire allowed greater bioavailability of critical nutrients - one of the reasons I'm not a supporter of raw veganism (though I don't try to stop raw vegans from being raw) ...we can simply digest and absorb nutrients more efficiently from cooked foods, with a few exceptions where raw is better. Humans evolved because of calorie density ...something we have no problem obtaining now as Western people in a culture that literally throws food in the garbage.

2) Even though the biology I took was specifically geared towards science majors and pre-meds, I think any one who took college biology at school that wasn't Bob Jones or Trump U should have learned that humans were not "made to eat" anything. Humans have the capability to eat anything, and our adaptability helps us to thrive as a species, but we were not "made to eat" any particular food. In fact studies of our teeth and digestive system strongly suggest herbivorous rather than carnivorous ancestors. This beautiful adaptation humans have is exactly why you can tell those silly heads that veganism is a perfectly acceptable diet for modern humans - precisely because we are adaptable.

3) Evidence suggests that vegetarians and vegans have smarter children with higher IQs than people who eat a traditional Western diet. However, correlation is not causation, scientists aren't sure yet if it's because of veg diets or because smarter people are more likely to go vegan (and therefore simply pass on smarter genes). Any health arguments against children being vegan are typically based in poorly planned diets, crazy abusive parenting in a small minority, and the "vegan children are smaller in stature" argument only applies to age 5, at age 10 vegan children are usually a similar height as their cohorts. Of course they're going to weigh less - Western children are obese.

4) Yes, there are tribes who would have not survived without fishing 1,000 or even 200 years ago. This argument doesn't stand up to the light in regards to factory farming, animal agriculture, and commercial fishing industries. Unless these dipshits actually live on a reservation and only gather their food with their bare hands, they need to sit down and shut up.
