Animals have evolved all sorts of special skills to find, attract, and keep their mates. Some rely on ostentatious plumage, others perform elaborate dances, and some just shout really really loudly. Humans don't have peacock feathers, but If we strip away the trappings of human culture, are there any parallels between our own ideas of love and sex, and those of our non-human cousins? If there are, what can we learn about our own relationships by better understanding animals? It turns out we're not the only species that experiences love and longing, and some animals are actually pretty kinky. You'll never think of dolphins the same way again.
