Evolution with Foresight: an oxymoron, right? Evolution has no foresight. Natural selection only promotes what works in the moment. If a particular mutation doubles your reproductive rate, you will fill the world with thy numbers; the process doesn’t understand too much of a good thing, doesn’t care if greater fecundity today means overpopulation, starvation, and […]

The Gene Genies, Part 1: The Squids of Lamarck.

You know the drill. DNA holds the source code; RNA carries it to the ribosomes; ribosomes build stuff for the cell. Of course, the details of cellular operation are a million times more intricate than this— some RNA acts not to courier code but to switch genes on and off, for example— but it’s this […]

Squids With Tasers.

A simple experiment, a famous fish. Electric eels, shocking their prey. Nothing to see here, right? “The mechanism of the eel’s attack is unknown”, Kenneth Catania states right off the top in his new paper in Science, and I admit I shrugged and thought What’s to know? What’s so mysterious about electrocution? But it turns […]
