The Upright Advantage: Walking and Health

Humans are odd in many ways. But perhaps the oddest of our features is our upright posture. We walk on two legs. And we are the only mammal to do so. 

So why do we walk upright? And why does it matter? 

Jeremy DeSilva is a fossil expert and a professor of paleoanthropology at Dartmouth College. He is also the author of a remarkable book, aptly titled First Steps: How Upright Walking Made Us Human

[An audio version of First Steps is now offered to you for free from Audible! See links and eligibility below.]

DeSilva’s treatment of the subject is sweeping: while tracing the journey of human posture, he draws remarkable links between bipedalism and many facets of the human condition from difficult births to complex language and from lower back pains to the beauty of friendships.

In this episode, we talk about questions such as:

1. What Darwin got right and wrong about the role of walking in human evolution
2. When and why did we start walking upright?
3. Why the common picture of human evolution is wrong - and what would be a better picture
4. Why walking makes us fragileHow our ancestors survived bone fractures - and this is a big deal
5. Why human birth is so difficult
6. Why walking is so good for us: introducing the “myokines”
7. What studying the human journey has taught DeSilva about our species
