What Humans Should Really be Thankful For
In this season of thankfulness, it's a good idea to move beyond being thankful for more food than we could ever eat and more family than we could ever argue with and take stock of other issues in our lives that deserve a nod.
We are humans, and this species has a lot to be grateful for. The first real human trait was bipedalism, walking on two legs, which appeared more than 4.5 million years ago. No one knows (not yet) why we became bipedal, but walking upright allows us not only to cover a lot of ground in an efficient way; it also allows us to carry things, like shopping bags and purses, or a cooked turkey on a platter.
