1. Evolution is always churning along. Evolution, after all, is just change over time and natural selection. … So whether we like it or not, evolution is going on, but it’s going on at a very slow pace. And really what’s a more dominant form of evolution today is cultural evolution: It’s how we learn and use our bodies and interact with each other based on learned information, and that’s also a kind of evolution. It’s not Darwinian evolution, it’s not biological evolution, but it affects our bodies. We’re evolving — we’re evolving slowly through natural selection and rapidly through cultural evolution, and we need to think about those interactions as we plan to use our bodies better.

    — Daniel Lieberman speaks to Fresh Air about how evolution is still pertinent today

  1. Evolutionary biologist Daniel Lieberman explains how we evolved to crave high-calorie sugary foods:

We evolved to crave sweet foods. Everybody loves sweet foods. But if you try to eat foods that hunter gatherers eat or chimpanzees eat, you’d be surprised at how unsweet they are. Most wild fruits are about as sweet as a carrot. So we love sweetness but until recently, pretty much the only food that we got that was sweet was honey and honey of course was a special treat, honey was pretty much the only form of dessert in the Paleolithic. But now we have access to abundant quantities of sugar and simple carbohydrates, which we evolved to love because they’re full of energy but we don’t have the metabolism. We don’t have the bodies that are able to cope with those kinds of levels of sugar and the result is that we get sick.
