We carry one of the world’s most fascinating rock collections inside us every day! These rocks (you may call them bones) are meticulously strung together to create our human forms. Cats have them, dogs have them, even birds and salamanders have them, but have you ever wondered why some creatures wear their skeletons on the outside? How did beetles and lobsters and ants end up walking around in a sort of home-grown body armor? And why don’t we?!
Long, long ago, deep in the sea, the crust of our planet was shifting. In the gaps that they left, millions of tiny particles trickled out. And it was in the slightly different ways that ancient creatures used these particles that set the stage for you and I and the dragonflies to end up looking drastically different from each other!
Can one tiny change really make this huge of a difference in our lives? I’ve got a little journey to take you on—one that explores the very origins of the skeletons inside us—to see how the smallest twists of evolutionary fate can have a monumental impact on the world!
The tiny changes that made you!
Humans could have looked SO different if not for a few small tweaks.
Millions of years of happenstance have led to us being able to do all that we’re able to do. We’re flexible yet strong, not the largest animal out there but clever and quick. But if our long-long-ago genetic ancestors made a few minuscule turns in the path of evolution, what it means to be “human” may have been the opposite of all of that!
As with most forms, we begin with our scaffolding; what holds us up and “desquishifies” us against the world. To continue our journey into understanding how a few random events long ago created life as you and I know it to be now, we’re turning to the fantastic Joe Hanson from It’s Okay To Be Smart!
This look into why our skeletons are inside of us—instead of us all rocking a sweet suit of armor—is one of my favorite videos from him yet. Enjoy!
How fascinating was that?! All of this information was new to me and I’m so thankful that Joe Hanson and It’s Okay To Be Smart are out there to keep making these introductions to these fascinating stories of our world!

All of this can get you wondering…
If one difference in how a mineral was used can wind up with us on one end of the skeletal line and stag beetles on the other, how does one difference in each of our individual experiences impact us?
If we’re each an accumulation of tiny differences—different structures of the same genetic bits, differences in locations, support as children, opportunities, and experiences—we’re sure to live our lives in different ways. It’s what makes you and I our amazing individual selves with all of our unique abilities!
By looking back at the chance circumstances that formed one of our most basic bits, we’re offered a lot of context in how these tiny differences in our lives can result in such a variety of personalities. And how there’s so much to celebrate in whatever the outcome!
It can also make one wonder about the influence of the small actions we take every day. How will what we do or learn today impact where we land in the future? Turns out, our very own scaffolding can give us a clue.
How nice is that?

I wonder what events will take place because of what happens in our lives today… or even because you used your finger bones to click on this article and watch that video. In any case, let’s do our best to make them positive, shall we? To learn about a great way to easily bring joy to your and someone else’s day, click here.
As always, my calcium-rich friend, stay open to new possibilities!
