spatial learning

Domestic animals and their wild counterparts can be different in big ways; there can be differences in morphology (physical characteristics), physiology, and behavior. These changes may depend on spontaneous adaptations to captivity or to artificial selection pressures arising from the motivation for domesticating the animal in the first place.
One change that is often observed as a result of…

Video 1: Gratuitous video of octopuses never hurt anyone. Maybe this will sate the Pharyngulites.
In the late 1980s, a researcher named Jennifer A. Mather wondered about octopuses' use of spatial memory. This researcher and some volunteers did some skin-diving near Bermuda and observed octopuses going out in search of food. They noticed that sometimes after catching a tasty bit of chow, the octopuses ate out, but sometimes they'd take their snack to go and eat at home. And not only that, but it turned out…
