It turns out that human beings have been using tools a lot longer than the scientific consensus used to allow.  A dissident scientist, who discovered the proof almost 35 years ago, stands vindicated, thanks to the development of technology.   Craig Welch of the Seattle Times reports:

It's not unusual for an archaeologist to get stuck in the past, but Carl Gustafson may be the only one consumed by events on the Olympic Peninsula in 1977.

That summer, while sifting through earth in Sequim, the young Gustafson uncovered something extraordinary - a mastodon bone with a shaft jammed in it. This appeared to be a weapon that had been thrust into the beast's ribs, a sign that humans had been around and hunting far earlier than anyone suspected.

Unfortunately for Gustafson, few scientists agreed. He was challenging orthodoxy with less-than-perfect evidence.

For almost 35 years, his find was ridiculed or ignored, the site dismissed as curious but not significant.

But earlier this month, a team that re-examined his discovery using new technology concluded in the prestigious journal Science that Gustafson had been right all along.

The most expensive scientific consensus in history, the warmist hypothesis, has never been scientifically proven with falsifiable proposition.
