Well…over the years black people sure have been blamed for an awful lot of things they didn’t do – but in this case it looks like tooth decay can actually be traced all the way back to our African roots. And yes…I did say “our African roots.”
According to a study by NYU College of Dentistry, Eve, whom many scientists believe to be our common African ancestor, is also the source of a bacteria associated with dental cavities. That’s one great granny who sure did get around!
But of course, if we have a common black ancestor, then this also means we’re all black – at least our untouched-up roots are. Something I’m proud to smile about – except when the dentist says “open wide”.
Excerpted from a March 14, 2007 press release
on New York University’s website:
“NYU College of Dentistry Study Finds Humans and their Oral Bacteria Evolved From a Common African Ancestor
A New York University College of Dentistry (NYUCD) research team has found the first oral bacterial evidence supporting the dispersal of modern Homo sapiens out of Africa to Asia.
The team, led by Page Caufield, a professor of cariology and comprehensive care at NYUCD, discovered that Streptoccocus mutans, a bacterium associated with dental caries, has evolved along with its human hosts in a clear line that can be traced back to a single common ancestor who lived in Africa between 100,000 and 200,000 years ago.”
