It had been many many years since I visited the Los Angeles Zoo last. While photographing the various exhibits, under clear blue skies, I was totally captivated by the chimpanzees. Their human-like characteristics are somewhat eery. And beyond the physical resemblance to humans, their social organization is obviously very complex. I spent at least thirty minutes observing them. If you recall, several years ago, the chimpanzee genome was sequenced and found to be around 96% similar to that of the human genome. Whether or not this should be surprising is probably still up for debate. Of the relatively few mammals with sequenced genomes, the dog (Canis familiaris) is one of them. In 2005, a twelve year old boxer named Tasha was fortunate enough to have her DNA fully sequenced. While no specific percentage was given, human and dog DNA is remarkably similar according to the experts. Eight of the top ten human diseases are shared by dogs. So despite dog's lack of resemblance to humans (for most of us at least!), they share an incredibly complex social hierarchy, just like chimps. But of course, if you are a dog owner, then you've already developed this appreciation!
