I have always treasured the diversity of living creatures like birds. But recently I have been treasuring how much we are the same.
Feathers show mind boggling diversity in their forms, from four-foot long pheasant tail feathers to almost microscopic cheek feathers on a hummingbird. Yet no matter how diverse feathers appear, they mostly share the same basic structure: shaft, barbs, and barbules.
Just like feathers have the same basic structures yet appear wildly different, we too have more similarities to all mammals, birds and fish than we do differences. We all have skin, livers, hearts, blood, lungs, bones, and nervous systems. We have indistinguishable cellular structures and functions from those of other creatures. We share almost all the same DNA. I treasure the diversity of life. But the sameness of life is also a source of wonder and connection. And this can challenge our perception of the world as revolving around us, humans.
People tend to focus attention on relatively minor differences between humans, and between ourselves and other creatures. Just like in medieval times, when we lived as though the sun and universe revolved around the earth, around ourselves, we still observe the world as human-centric. Well, we are not the center of the universe, nor are we the center of life on earth. We are part of it, we are unique but so is each living creature. And our unique-ness doesn’t mean we’re really all that different.
