Myrmecomorphy

Ants are one of the most abundant groups on earth, but, curiously, not a lot of things eat them. Yes, there are anteaters (who also eat a lot of termites), and some lizards specialize on ants, but the little critters are full of noxious chemicals and pheromones that put them way down on the list of predators’ preferred foodstuffs. Because of this, many other insects and arthropods have evolved to mimic ants, taking advantage of the aversion of predators to anything antlike. These mimics are called myrmecomorphs, and they’re the subject of a really nice eponymous feature in this week’s Current Biology.

Inclusive fitness theory and eusociality

Big dust up about kin selection. Biologists E.O. Wilson, Martin Nowak, and Corina Tarnita publish a paper attacking kin selection, the idea that the reproductive success of a gene is influenced not only by its effects on its carrier, but also by its effects on related individuals (kin) carrying the same gene. 130 some odd other biologists respond. Richard Dawkins weighs in. Some talking bears offer a summary. [via]
