How Hair Works (Originally aired August 3,2018) Guest: Duane P. Harland, PhD, Senior Scientist, AgResearch New Zealand Hair is one of those things we don’t think much about beyond how well it’s cooperating on a given day. But it’s kind of amazing and mysterious: Is it made of living or dead cells? Why does it curl? Why does it turn gray as we age? Why does its texture differ from person to person and even from place to place on our bodies? Why is it greasy for some people and dry for others? When you bleach or color it, what exactly is happening to the hair?  A Believer’s Take on Human Evolution (Originally aired August 3,2018) Guest: Steven L. Peck, PhD, professor of evolutionary ecology, BYU, author of “Evolving Faith”  Is it possible to believe that we humans evolved from a lower life-form and also believe in divine Creator? Isn’t it one or the other? You either believe the Bible’s account of Adam and Eve, the first humans created by the hand of God, or you believe Charles Darwin’s theories “On the Origin of Species” and “The Descent of Man.” The two seem entirely incompatible. But BYU evolutionary ecology professor Steven L. Peck finds them compatible enough that his belief in the scientific evidence for evolution actually strengthens his belief in God.
