It kinda put us into a little perspective, like the pale blue dot.
What it immediately remind me of was a creation of Matt Might:
I would confidently suggest that circular family tree - I'm sure there's a fancier name - is representative of hundreds or even thousands of PhDs. Apparently there are ~3000 species in the tree.
Incorporate this body of knowledge with those boundaries it shares with physics, geology, paleontology etc... you have the a predictive scientific theory, such as the Theory of Evolution.
And to think what I do from day to day, I wouldn't get past the middle of the red, depending on how we compare academics to those in the field.
