Human Errors

An illuminating, entertaining tour of the physical imperfections, from faulty knees to junk DNA, that make us human - and a unique approach to telling our evolutionary history

---

We like to think of ourselves as highly evolved creatures. But if we are evolution's greatest creation, why are we so badly designed? We have retinas that face backward, the stump of a tail, and way too many bones in our wrists. We must find vitamins and nutrients in our diets that other animals simply make for themselves. Millions of us can't reproduce successfully without help from modern science. We have nerves that take bizarre paths, muscles that attach to nothing, and lymph nodes that do more harm than good. And that's just the beginning of the story.

As biologist Nathan H. Lents explains, our evolutionary history is a litany of mistakes, each more entertaining and enlightening than the last. As we will discover, by exploring human shortcomings, we can peer into our past, because each of our flaws tells a story about our species' evolutionary history.

A rollicking, deeply informative tour of our four-billion-year-long evolutionary saga, Human Errors both celebrates our imperfections - for our mutations are, in their own way, a testament to our species' greatness - and offers an unconventional accounting of the cost of our success.
