Happily, we can tune out these diet extremists and have a look at the data ourselves. There are three lines of solid evidence that tell us something about the diets our ancestors ate: the archaeological and fossil record, ethnographies of living hunter-gatherers, and functional analyses of the human genome. The details differ and it’s easy to get lost in the weeds, but the overarching message from each is clear: we evolved as opportunistic omnivores. Humans eat whatever’s available, which is almost always a mix of plants and animals (and honey).
