Human Errors

We like to think of ourselves as highly evolved. But if we are evolution's greatest creation, why are we so badly designed? We have retinas that face backward, we must find vitamins and nutrients in our diets that other animals simply make for themselves and millions of us can't reproduce successfully without help from modern science. And that's just the beginning of the story. Biologist Nathan H. Lents takes us on an entertaining and illuminating tour of our four-billion-year-long evolutionary saga, and shows us how each of our flaws tells us a story about our species' history.

An illuminating, entertaining tour of the physical imperfections that make us human We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution's greatest creation, why do we have such bad knees? Why do we catch head colds so often--two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there's been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them. A rollicking, deeply informative tour of humans' four billion year long evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success.
