Polar Play: Animals Have Fun Too

baby polar bearWe have all seen parrots talk, lionesses work as a team to hunt, and apes use tools to get the job done.  Humans tend to assign many behaviors a “human only” label; however, in reality, talking parrots are only the tip of the iceberg.

To those of us who have interacted with dogs, it is abundantly clear that animals take part in playful activity in the same way humans do.  But just how common is animal play, and why and to what extent do they do it?

When Brian La Doone’s sled dog Hudson approached a wild, hungry-looking polar bear, La Doone thought that was the end of Hudson.  But instead, he was in for a pleasant surprise.  Hudson and the bear began playing with each other, rolling around and wrestling in the snow, even embracing and nipping at each other.  Apparently the two playmates enjoyed each other’s company so much that they met for a playdate every night for a week!

Evolutionary psychologists believe there must be benefits to play, because usually it makes you less fit than you were at the start:  animals could become injured, expend energy, and become distracted from predators.  Some biologists believe play could prepare you for survival activities, such as dogs and lions pouncing with each other and gazelles running to become speedier, and others have discovered evidence that play is good for the brain and for building social connections.  Some scientists even think that humans should play more as adults, and that we would benefit enormously from doing so.

A Bee’s Buzz

Where do bees get their buzz?  No, I’m not referring to the sound their vibrating wings make when they fly.  In fact, I’m talking about a much more colloquial “buzz” – the one you get from caffeine when you drink a cup of coffee.  It turns out bees also enjoy the little boost in energy they reap from coffee plants when they drink the nectar, which contains low levels of caffeine that the pollinators obtain much satisfaction from.

Plants originally evolved caffeine as a defense against herbivory because it can be toxic at high levels.  However, at low levels, it encourages honeybees to return to the plant – thus increasing the plant’s pollination efficacy – because the honeybees’ learning and memory abilities are enhanced, and therefore the honeybee reaps a benefit from the plant.  So what began as a deterrent for herbivores is now a triple whammy for the plant, which now 1) attracts more bees because the bee enjoys the caffeine buzz, 2) ensures the bee will return because its learning and memory are enhanced due to the caffeine, and 3) repels herbivores at the same time!
