One of the things that I have found most interesting, but have not been able to find much info on, is the revelation that there was a "bottle-neck" discovered through DNA testing. That human population was reduced to as little as 100 individuals as recently as 20,000 years ago.

According to the Toba catastrophe theory, 70,000 to 75,000 years ago a supervolcanic event at Lake Toba, on Sumatra, reduced the world's human population to 10,000 or even a mere 1,000 breeding pairs, creating a bottleneck in human evolution. The theory was proposed in 1998 by Stanley H. Ambrose of the University of Illinois at Urbana-Champaign.[1][2]

Clues from genetics, archaeology and geology suggest our ancestors were nearly wiped out by one or more environmental catastrophes in the Late Pleistocene period. At one point, the numbers of modern humans living in the world may have dwindled to as few as 10,000 people.

Do what? How do you feelings of being irked over grammatic "thru" versus "through" contribute to this discussion? Sounds like static to me. There are shortcuts of english to emote expression. LOL
