Beware the uneducated...

Check out YouTube for a stupendous amount of stupidity related to 'proof' of the Earth being flat.  These people are serious - they have 'proof'. Mathematics, Physics and Logic are not subjects with which they are familiar.

What does this sentence mean? -

"We were told at the time that they did, but I gather the later conclusion is that light-winged moths started to die off, and dark-winged moths correspondingly prospered."

Who are 'We' and who told you that?  This happened 150 years ago - in Europe.

YOU should never have been told that was true in any American science class.

The black/white moth scenario is a classic example of Charles Darwin's Natural Selection. The white moths die off; the black moths live to procreate.

Lamarck's theory was that species could 'adapt' (alter their appearance, or whatever other change was necessary) within a single lifetime and pass that change onto their progeny.

Genetics, anyone?

>The article says in part "It’s sort of like the moths in Europe that swapped speckled for black wings during the Industrial Revolution, evading hungry birds by blending in with coal dust."  I read that without a qualm the first time through, forgetting until just now that the famous moths didn't adapt.  We were told at the time that they did, but I gather the later conclusion is that light-winged moths started to die off, and dark-winged moths correspondingly prospered.

>I have a hard time taking the Flat-Earth society seriously, by the way.  I got the impression somewhere that it's sort of an insider joke, that they don't really believe the earth is flat.  I shouldn't underestimate the stupidity potential—maybe a few do—but not the membership as a whole, surely.

>>First we have the swelling ranks of the 'Flat Earth Society', now we have a 'Science' writer for the NYT talking about moths, pigeons and sea snakes 'adapting' (quickly, no less) to pollution!!!!

>>LaMarck would be proud.
