Evolution of schooling behavior in fish is discussed. For the first time, schooling was formed in early Teleostei ca 200-220 Ma years BP. There are no strict data on the presence of this form of social behavior in older Craniata. It is supposed that the evolutionary path of schooling ...

Smaller brain size may also indicate that their other senses were less acute, predatory behavior less flexible, and social dynamics less sophisticated than in most modern sharks (especially the whalers and hammerheads). Skeletal view of a Devonian shark.View of a modern shark.The teeth of the e...

Our study highlights that (a) predatory fish can have a profound influence on the expression of mating preferences of their prey (thus potentially affecting the strength of sexual selection), and females may alter their mate choice behavior strategically to reduce their own exposure to predators. ...
mentioned in this blog, this elephant-like beast might even have a similar appearance and similar life history characteristics. If the planet were water, we might find similarities to earth as well—perhaps some schooling fish-like species, larger predators, bottom-dwellers, broadcast spawners, etc...

A tweet from Barry. I suspect this is a purely learned rather than an evolved behavior, and it may have started from the birds soaking bread in the water before eating it, but now it is most clearly FISHING! Green heron using a piece of bread as bait to catch a fish. Amazing example...
(see for example, Isaak2006). Indeed, instead of undermining ethical behavior, according to some scientists, evolution provides a basis for ethical behavior (see for example Ayala1987,2007). Nonetheless, this misconception persists and research suggests that educators should address directly these ...
