I meant to point out the difference between "design" the verb/adverb and "design" the noun. It is in our "design" that we can eat meat, but nothing actively "designed" us to do that.
Using the same theory, our ability to adopt and thrive on a vegan diet is a survival mechanism. Like I said, we're generalists. Our ability to use meat as a rich source of nutrients such as protein, vitamin B, and iron, as well as our ability to survive on plant life pretty much exclusively, is a result of our many generations of natural selection. Those species who fail to adapt to their environment? They certainly aren't on the menu anymore.
