I believe it was the first day of class that someone stated that one of the major differences between humans and animals was the idea of trade, animals can’t do it. However, contrary to the discussion held in class I found an interesting article titled “Pick Up a Penguin” on the BBC world news page.
In this article I discovered that economics is not unique to humans; Adelie penguins on Ross Island at the South Pole were discovered participating in an economic phenomenon. Male penguins go out and collect stones and give them to the female penguins, in return the females provide sexual favors for the males. (So much for the idea that Penguins faithfully mate for life). These rocks and stones are used to make nests and are hard to come by, a limited resource that is necessary for the survival of the female’s eggs. The stones are so valuable sometimes they are even stolen from other penguins, which makes these stones and rocks very valuable and in high demand.
