Uh, hadn't Africans already been enslaved in the Americas for generations when these drawings were made? We're talking the late 1700s here - for all you know those are ACTUAL recent slave descendants from Africa in the pictures. Or mixed. Why just assume they were OG natives? How would some random European know the difference?
And 17th/18th century CAC artwork ain't really a strong go-to source for accurate depictions. Ya'all can't figure out subtle racial features or skin tone from a fukking old-school European artist - dem dudes were NOT balling with the accuracy like that.
This is what they thought sloths looked like:
Hyena
Walrus
Hippopotamus
Hoolock Gibbons
A bit older (1300s)....an elephant
Elephant seal
90% of the time when they were drawing shyt from the "New World" or Africa they didn't know what the fukk they were drawing. I'm sympathetic to some of the evidence that West Africans visited Central America/Caribbean...but this is NOT it.
