The Falsehoods

Biology is harder to learn than quantum physics. Why? Because most people think they totally get biology, but everyone knows nobody gets quantum physics. Therefore, any effort to explore quantum physics will result in new learning, but people rarely learn new biology. The bottom line is that our brains are full of biology, which would…

Is the Natural World a valid source of guidance for our behavior, morals, ethics, and other more mundane areas of thought such as how to build an airplane and what to eat for breakfast?1 When it comes to airplanes, you’d better be a servant to the rules of nature (such as gravity) or the airplane…

The Science of Lion Prides

Although the paper addresses Tanzanian lions, this is a photograph of a Namibian lion Starting some years ago, we began to hear about revisions of the standard models of lion behavioral biology coming out of Craig Packer’s research in the Serengeti. One of the most startling findings, first shown (if memory serves) as part of…

In an BBC article describing a Royal Society paper on the rate of mutation in warm vs. cooler climates, the BBC made this statement: DNA can mutate and change imperceptibly every time a cell divides and makes a copy of itself. But when one of these mutations causes a change that is advantageous for the…

Why does a soldier throw himself on a hand grenade to save the lives of a half-dozen unrelated fellow soldiers? Why does someone run into a burning building they happen to be passing to save a child they don’t know? From a Darwinian perspective these seem to be enigmatic behaviors that would “select against” such…

According to a study just coming out in the Journal of Sexual Medicine, “variations in emotional intelligence–the ability to identify and manage emotions of one’s self and others–are associated with orgasmic frequency during intercourse and masturbation.”

Gallup has taken on the task of explaining, in ultimate terms, the evolutionarily designed features of the human penis. He works this as an engineering problem from the perspective of evolutionary psychology, which is always a little bit dangerious, but gallup isn’t quite the arm waiver that a lot of other EP’s are, so he…

Where have all the ducklings gone??

Or, more exactly, where are they all going to go during the next two or three months? I’m sitting here between a large frozen lake and a small “pond” (connected to the lake with a channel) that has patches of open water on it. (The melting on the pond is probably because the bioactivity at…
