Unlike Global Warming the Science of Evolution has Evolved

Week in Review

Devout global warming alarmists say the science is done.  There is a scientific consensus.  Manmade global warming is real.  Case closed.  And if you deny that global warming exists you are going against settled science.  There is only one problem with this.  There is no such thing as consensus in science.  And science is never settled (see 7,000-Year-Old Human Bones Suggest New Date for Light-Skin Gene by Tia Ghose posted 1/26/2014 on Yahoo! News).

An ancient European hunter-gatherer man had dark skin and blue eyes, a new genetic analysis has revealed.

The analysis of the man, who lived in modern-day Spain only about 7,000 years ago, shows light-skin genes in Europeans evolved much more recently than previously thought.

The findings, which were detailed today (Jan. 26) in the journal Nature, also hint that light skin evolved not to adjust to the lower-light conditions in Europe compared with Africa, but instead to the new diet that emerged after the agricultural revolution, said study co-author Carles Lalueza-Fox, a paleogenomics researcher at Pompeu Fabra University in Spain…

The finding implies that for most of their evolutionary history, Europeans were not what many people today would call ‘Caucasian’, said Guido Barbujani, president of the Associazione Genetica Italiana in Ferrara, Italy, who was not involved in the study.

Instead, “what seems likely, then, is that the dietary changes accompanying the so-called Neolithic revolution, or the transition from food collection to food production, might have caused, or contributed to cause, this change,” Barbujani said.

In the food-production theory, the cereal-rich diet of Neolithic farmers lacked vitamin D, so Europeans rapidly lost their dark-skin pigmentation only once they switched to agriculture, because it was only at that point that they had to synthesize vitamin D from the sun more readily.

This is science.  We had one theory.  And replaced it with another.  As we may do again.  Because science is never settled.  And there is no such thing as consensus.  Which is why global warming is not science.  It’s politics.  Because politicians say there is a consensus.  And that it’s settled.  But in science we don’t take a vote.  We hold one theory true.  And spend our time trying to prove that theory is wrong.  And when a theory withstands all of these efforts to disprove it that theory is a pretty strong theory.  But it doesn’t mean we stop trying to find a better one.  As proven here.
