`  § I got in touch with the owner of the website mentioned above, and he has offered to e-mail me a scanned copy of the map in the book illustration, which shows an intermediate band where the white band occurs near the northern tip of Africa.  I had a closer look at the maps I found in the library, and none of them improves on what was in that website. The one major difference that a revised map probably ought to take account of is the division of Australia into two regions. I'll make overlays to check, but it looks like the only other changes involve reducing 8 zones to 5. If you check out the Cavelli-Sforza map (which I now think is a photo reproduction of the original map) you can easily understand why authors would decide to simplify the number of zones  Cavelli-Sforza's map is o.k. for the lighter half of the shades of skin color, but the darker shades are practically indistinguishable.  Sometimes, if you know where to look, you will see what looks like a little halftoning rather than straight black ink. But for practical purposes the map is pretty useless outside of the values that are shown in the Americas.   § In a way it was a good thing that the original map was so washed out. If I hadn't really looked carefully at it I'm pretty sure I'd have missed the white band. The uncorrected map has propagated so many places on the WWW that it's hard to believe the original maker of the digitized image has any objection to others using it.    ==Cleanup== We need to clean up the article. The sections should only treat what it says they do in the section title. For example, there shouldn't be a paragraph `` :``In everyday speech, race is often used to describe populations that are better defined as ethnic groups...`` at the end of ``History of the term``. Nor should the ``Anthropology and genetics`` section, being placed after the history section, i.e. we are through with the historical aspect now, begin with  :``In the 19th century many natural scientists made three claims about race: ...`` (i.e. this bit still belongs in the 'history' section). Also the case studies (USA, Brazil) should either be exported to special articles, or at least be placed after the more general phylogenetic subsection. Somebody should read the entire article and weed out repetitions, too.    == Von Luschan scale ==  § The von Luschan scale was a manufactured set of standard tiles that were colored so that a researcher could in relatively rapid order sort through his/her tiles and find the one that came closest to matching a given subject's skin color. Essentially the same method is still used today, at least in this increasingly anti-scientific nation, by dentists who want to match ceramic material used for making fillings with the color of their patient's tooth. They have a little cabinet full of ceramic ``teeth`` on little spindles. Each specimen has a different combination of hue and brightness from the others. Although one could easily create an electronic device to measure these factors to tighter tolerances, the low-tech device seems to meet professional standards. Similarly, given the fact that a subject's skin color could vary considerably due to contingent factors such as season and weather patterns, the von Luchan tiles probably provide all the accuracy that is useful. `
