The article, which is about human evolution, starts out like this:

Despite the sheer enormity of our planet, we humans are far more closely related than we should be.

Say what?

Apparently MSNBC thinks the vile wickedness of our planet exists despite how closely related people are, even though there might be something pervy about it.

Ye gods.

Okay, maybe not pervy, but we certainly shouldn't be that closely related.  Maybe.
