A Male Chimp Can Spot an Ovulating Female From More Than a Quarter Mile Away

An ovulating female chimp, that is. Nearly all female primates advertise their days of fertility with colorful genital swellings.

And that’s why I slept in and didn’t go… Read more →

Humans Evolving to Become Less Intelligent?

Gerald Crabtree, a geneticist at Stanford University, suggests that humans are evolving to become less intelligent. Crabtree asserts that the safer life gets for humans, the less important it is for us to have good judgment for survival and mating. Thousands of years ago, human idiots were much more likely to be removed from the gene pool (i.e., die) as… Read more →

God’s Gift to Kansas

The creationists’ fondness for ‘gaps’ in the fossil record is a metaphor for their love of gaps in knowledge generally. Gaps, by default, are filled by God. You don’t know how the nerve impulse works? Good! You don’t understand how memories are laid down in the brain? Excellent! Is photosynthesis a bafflingly complex process? Wonderful! Please don’t go to work… Read more →
