Flies do vector math?
Neurons in the fly brain appear to literally perform vector math in order to signal the direction in which their bodies are traveling, regardless of which way their heads are pointing. … “Not only do these neurons signal the fly’s direction of travel, but they do also so in a world-centered reference frame,” says Rockefeller neuroscientist Gaby Maimon. What’s remarkable, adds first author Cheng Lyu, a graduate student in the Maimon lab, is that these insects are transforming body-referenced sensory inputs into a world-referenced signal, allowing the fly to know that it is traveling, for instance, 90 degrees to the right of the sun or northward.

When they are explaining stuff like this, you have to know that they are not talking about Darwinian evolution. Whatever they may claim.
