A new study found a relationship between the types of chimps calls, and their discovery of delicious fruits. Seems like they might be talking about the quality and quantity of the fruit on a tree.
Sister fish stick together
Cichlid fish are really cool! Recently, it was discovered that among African Neolamprologus caudopunctatus, the females are the ones who disperse, not males. In groups of fish, DNA analysis revealed that small females tend to hang with their bigger sisters. This kind of sibling-shoaling was not found in males of the same species.
The uncanny valley is that strange feeling you experience when you see something that is almost, but not quite, human-like, such as animation in a film or video game, or robotic movements that mimic our own. You may even experience this feeling when you see other primates. Some folks have suggested that "the valley" may be what caused us to kill off Neanderthals (although I'm still looking for a more reputable source on this topic)!
Long story short, turns out that a recent study suggests that monkeys are also disturbed by almost life-like images of other monkeys. Marc Bekoff gives some nice explanations for why animals might be hardwired to look for stimuli that match expectations of what other members of their species should look or act like (or as another scientist points out, these likenesses may not be visual at all, but could be sound or olfactory-based).

What is the deal with emotional support animals? For the record, they are not the same thing as a service animal - but there's a lot of confusion about what is allowed and what isn't - and it's easy to fake a letter. Patricia Marx goes undercover and explores what happens when you bring a "therapy turtle" to a museum. Read here!
