Can you name a modern or even ancient tribe that do not have fashion?

I think we can safely say that the oldest professions are hunting and gathering.

After that, it was certainly the tribe's medicine man/woman. Then probably the one who figured out how to ferment grains and brew beer.

One of my favorite series, although Brian Jacques's long "Redwall" series is a close competitor, and of course Harry Potter and Alan Dean Foster's Spellsinger books. (Mrs. Fraggle, an English major, insists that some of the world's best literature was written for children, and she's right.)

Jean Auel did a lot of research to prepare for the "Earth's Children" books. She practically apprenticed herself to several anthropologists, and even spent an entire winter in a cave in Alaska. Unfortunately it took her so long to complete the series that our knowledge of the Paleolithic Era has increased and some of the things in the first books are incorrect. Most notably, it turns out that the Neanderthal brain had a speech center. Much of the tension and distrust between the Neanderthals and the sapiens in her stories comes from the fact that the Neanderthals could only communicate in sign language, which is probably not true. We've also discovered that the Cro-Magnon did not kill off the Neanderthals, but merely absorbed them by intermarriage. Most of the people in Europe who can count the Cro-Magnon as ancestors (e.g., not the Huns, Finns, Turks, Magyars, Saami and Jews) have a measurable percentage of Neanderthal DNA, which other modern humans lack.

 

Much of this article conflicts with the discoveries of Dr. Cavalli-Sforza, who mapped the migratory routes of ancient Homo sapiens in excruciating detail by taking thousands of DNA samples. His research dated the first migration out of Africa much more recently, 60KYA. And he found no back-migration into Africa until (possibly) around 12KYA when the Sahara was repopulated. It's tempting to assume that it was settled by adventurers from Asia, who brought the technologies of farming and animal husbandry with them, making it possible to grow food there, and jump-starting the Neolithic Revolution on a new continent.

But it's also possible that it was settled by Africans who discovered agriculture on their own and slowly moved north "because it was there." The DNA of modern North Africans is such an olio that we can't possibly trace it back. Even their languages are enigmatic: the Afro-Asiatic family stretches from Morocco to Mesopotamia.
