Scientists now say that the petroglyphs at Pyramid Lake, Nevada, are the oldest in North America to have been age-dated. Though appearing confident about some details, they cannot yet identify the ancient peoples who carved those rocks. But the ancients did possess one characteristic that surprised secular scientists.

Colorful Heliconius butterflies grace the tropics with their beautiful wide wings. Their survival depends on more features than what simply resides in their physical bodies. The challenge is trying to explain the origins of the way their body parts not only mesh perfectly with each other, but also with their butterfly behavior.

The onset of pregnancy presents an apparent contradiction. Ovulating and initially pregnant mothers experience an increase in progesterone. On the one hand, this hormone signals the immune system to back down and lay low. That's critical, because otherwise her body would fight and kill sperm cells as though they were unwelcome invaders, and she would never become pregnant.

The human Y-chromosome has been a sore point among secular scientists in recent years because of its many anti-evolutionary surprises. Adding to the Darwinian grief, is yet one more shocking Y-chromosome study that more clearly illustrates the boundaries of human genetic diversity.
