It is a truth near-universally acknowledged that dogs are a man, woman and child’s best friend.
But there’s more to dogs than Frisbee tossing and a warm companion on a chilly evening. In the current issue of National Geographic magazine, a fascinating report details how scientists have discovered a kind of secret recipe behind the tremendous variety of dog shapes and sizes, and it just might help decode the “complexity of human genetic disease.”
“The story that is emerging,” says Robert Wayne, a biologist at UCLA, in National Geographic, “is that the diversity in domestic dogs derives from a small genetic tool kit.”
Take a look at eight gorgeous portraits (featured in the February 2012 issue of National Geographic magazine) of dogs from the 2011 Westminster Dog Show and understand with your kids how scientists are learning about more than just friendship from our four-legged friends:
