It is amazing that any article would appear in (un-)Scientific American that doesn't allude to it. Their obsession with pushing what isn't even a proper theory, just an unproven hypothesis, lost me as a former subscriber. Same with National Geographic and so much other respectable media taken over by Leftist ideologues.
National Geographic resorted to repeatedly running photoshopped fakes.
There is no scientific purpose served, at least one was an editorial decision.
