The highly acclaimed Edge Foundation has 120 prominent minds commenting on John Brockman's question: "WHAT DO YOU BELIEVE IS TRUE EVEN THOUGH YOU CANNOT PROVE IT?"
JARED DIAMOND, Professor, biologist and geographer at UCLA and author of Collapse: How Societies Choose to Fail or Succeed, believes that:
"[H]umans first reached the continents of North America, South America, and Australia only very recently, at or near the end of the last Ice Age."
Diamond also writes:
Every year, discoveries of many purportedly older sites are announced, then to be forgotten. As the supporting evidence dissolves or remains disputed, we're now in a steady state of new claims and vanishing old claims, like a hydra constantly sprouting new heads."
The reason, says Diamond, is:
"It makes better newspaper headlines to report "Wow!! New discovery overturns the established paradigm of American archaeology!!" than to report, "Ho hum, yet another reportedly paradigm-overturning discovery fails to hold up.""
We agree.
