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. It seems like a useful indicator for humans trying to have babies or trying not to have babies, but for some reason evolution has seen fit to conceal the reproductive state of human females from observation.

I Slept Late But There’s a Reason for It

 

Think about our distant ancestors . . . energy in the form of food was scarce and hard to obtain. Those who survived had a genetic predisposition to not use energy wastefully but rather to store it up for times when it was really needed. This gave them an evolutionary advantage. And that’s why I slept in and didn’t go to the gym this morning . . . Read more →

Happy Darwin Day!

 

“I’ve been walking three miles a day. I thought my cardio fitness was pretty good. Then today I tried swimming some laps and found out that my fitness level is not what I thought it was.” “Yes, well, it’s a good thing that complex life emerged from the seas so we can all spend more time walking and less time swimming. Happy Darwin Day!“ 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 a result of their lack of intelligence and judgment. Nowadays, it’s rare for someone to die because they were unable to outwit a predator. Read more →

Passion

 

The theory of evolution claims that only the strong shall survive. But the theory of competition says that just because they’re the strong doesn’t mean they can’t get their asses kicked . . . 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 on the problem, just give up, and appeal to God. Dear scientist, don’t work on your mysteries. Bring us your mysteries for we can use them. Don’t squander precious ignorance by researching it away. Ignorance is God’s gift to Kansas. — Richard Dawkins, “Creationism: God’s gift to the ignorant” Read more →
