Are Humans Still Evolving?
Anybody who teaches human evolution is inevitably asked: Are we

answer. Certainly many types of selection that challenged our ancestors
no longer apply: improvements in nutrition, sanitation, and medical
care have done away with many diseases and conditions that killed our

The Adverse Health Effects of Formula Feeding
More significantly, the breast—bottle controversy has moved far away from the question of what is best for babies.
