In his report on animal species that appear to have numeracy skills (20 June, p 37), Ewen Calloway says: “The ability to count may date back to even more primitive organisms than fish,” citing bees as an example.
Bees more primitive than fish? Not at all. Bees evolved more recently than fish by about 400 million years. Their social and working lives are more complex than those of fish, and they are known to communicate information about direction and distance by sign language. What fish can do that?
