A Textbook Case of Junk Science

This Pamela R. Winnick article says:

Several centuries ago, some "very light-skinned" people were shipwrecked on a tropical island. After "many years under the tropical sun," this light-skinned population became "dark-skinned," says Biology: The Study of Life, a high-school textbook published in 1998 by Prentice Hall, an imprint of Pearson Education.

"Downright bizarre," says Nina Jablonski, who holds the Irvine chair of anthropology at the California Academy of Sciences. Jablonski, an expert in the evolution of skin color, says it takes at least 15,000 years for skin color to evolve from black to white or vice versa. That sure is "many years." The suggestion that skin color can change in a few generations has no basis in science.

Pearson Education spokesperson Wendy Spiegel admits the error in describing the evolution of skin color, but says the teacher's manual explains the phenomenon correctly. Just why teachers are given accurate information while students are misled remains unclear.

It seems clear to me. Evolution is taught in a distorted way in order to reinforce certain political propaganda messages. In this case, leftist egalitarians want to force schoolkids to think that evolution proves that racial differences are insignificant.
