The findings can shed light on an evolutionary adaptation that enabled the human brain to grow to modern-day sizes. “Humans evolved in equatorial Africa, where the sun is overhead for much of the day, year in and year out,” says Nina Jablonski, professor of anthropology at Penn State. “Here the scalp and top of the head receive far more constant levels of intense solar radiation as heat. “We wanted to understand how that affected the evolution of our hair. We found that tightly curled hair allowed humans to stay cool and actually conserve water.” The researchers used a thermal manikin—a human-shaped model that uses electric power to simulate body heat and allows scientists to study heat transfer between human skin and the environment—and human-hair wigs to examine how diverse hair textures affect heat gain from solar radiation.

Hi!
Asking because you’re a librarian: I read 1491 and liked it; what other nonfiction books would you recommend on precolonial Indigenous civilizations in the Americas, especially on civilizations other than the famous (Aztec, Mayan, Inca) ones? I was especially interested in the parts on Amazonian civilizations.
Hello! I'm hopefully living up to my librarian title with these titles!
Indians Before Columbus; Twenty Thousand Years of North American History Revealed by Archeology by Paul S. Martin
Fair Gods and Stone Faces by Constance Irwin
America Before: The Key to Earth's Lost Civilization by Graham Hancock
The First Americans: The Pleistocene Colonization of the New World edited by Nina G. Jablonski
Daily Life in Pre-Columbian Native America by Clarissa W. Confer
This is only a handful of what I was able to find, but there is plenty more if you'd like those as well. Hope you find something you like in this list and happy reading!

AMERICAN ASSOCIATION OF PHYSICAL ANTHROPOLOGISTS MEETING:
European Skin Turned Pale Only Recently, Gene Suggests Ann Gibbons
PHILADELPHIA, PENNSYLVANIA–At the American Association of Physical Anthropologists meeting, held here from 28 to 31 March, a new report on the evolution of a gene for skin color suggested that Europeans acquired pale skin quite recently, perhaps only 6000 to 12,000 years ago.
Science 20 April 2007: Vol. 316. no. 5823, p. 364 DOI: 10.1126/science.316.5823.364a
http://www.sciencemag.org/cgi/content/short/316/5823/364a Comments on the recent genetic studies:
This research conducted by Europeans descendants seeking the roots of their origin supports the view that the first pale-skin European was born 6,000 years ago. In 2005, researchers linked the paleness of the modern European skin to a mutation in gene SLC 24A5. Its implication is immense if fully comprehended. The “whites” or Caucasians are not native to Europe as noted by Sokal. Haak et al (2006)
1.5 million years ago when human beings first began to evolve in Africa, they had Black skin. 100,000 years ago when anatomically modern humans evolved in Africa, they gave rise to the Black man and woman.
They lived in Africa as Black people, some of these people left Africa, 50,000 years ago as Black people, entered Europe as Black people, and they settled and lived in Europe as Black people until 6,000 years ago when the mutation that gave rise to the pale-skin arose.
Rogers posits that all people having descendants today had exactly the receptor protein of today’s Africans; their skin was black, and the intense sun killed off the progeny with any whiter skin that resulted from mutational variation in the receptor protein (Rogers 2004:107).
Nina Jablonski claims that dark skin evolved pari passu with the loss of body hair and was the original state for the genus Homo.
Furthermore, it is generally accepted as argued by Rogers that the descendants of any people who migrate North from Africa will mutate to become white over time because the evolutionary constraint that keeps Africans’ skin black generation after generation decreases generally the further North a people migrates (Rogers 2004).
However the surprise is that this mutation only occurred after more than 45,000 years in which only Black-skinned African people lived in Europe as its original human aboriginals. It cannot be over-emphasized that it was only in the last 6,000 years that the pale-skin (aka whiteman) first appeared.
The mutation gene must have spread gradually (as often occurs with new mutation) from that time but it surely would have taken another two or three thousand years down the line before it would become the dominant European profile. That makes it just three thousand years ago.
It was only three thousand years ago that whiteman became the dominant type in an African-owned Europe! Before that it was Black-skinned African. For more than 48,000 years Black-skinned Africans would have been the only Europeans!!! Europe was discovered and mapped by Black skin Africans. Europe of yesterday, today and tomorrow will ever remain Africa’s heritage. Osteological Evidence:
In 2006, Brace a leading authority in anthropology conducted osteological analysis on several skeletal remains dating from neolithic Europe.
According to Brace:
“Many human craniofacial dimensions are largely of neutral adaptive significance, and an analysis of their variation can serve as an indication of the extent to which any given population is genetically related to or differs from any other.
When 24 craniofacial measurements of a series of human populations are used to generate neighbor-joining dendrograms, it is no surprise that all modern European groups, ranging all of the way from Scandinavia to eastern Europe and throughout the Mediterranean to the Middle East, show that they are closely related to each other.
The surprise is that the Neolithic peoples of Europe and their Bronze Age successors are not closely related to the modern inhabitants, although the prehistoric/modern ties are somewhat more apparent in southern Europe.
It is a further surprise that the Epipalaeolithic Natufian of Israel from whom the Neolithic realm was assumed to arise has a clear link to Sub-Saharan Africa.
……………………..
The data treated here support the idea that the Neolithic (i.e. Natufians with a clear link to Sub-Saharan Africa) moved out of the Near East into the circum-Mediterranean areas and Europe by a process of demic diffusion but that subsequently the in situ residents of those areas, derived from the Late Pleistocene inhabitants, absorbed both the agricultural life way and the people who had brought it.
C. Loring Brace: The questionable contribution of the Neolithic and the Bronze Age to European craniofacial form; PNAS | January 3, 2006 | vol. 103 | no. 1 | 242-247
There are no ancient skeletons of the Caucasian type. The findings of Brace et al make it clear that there were no whites in ancient Europe. There were only Black Africans living there until the coming of the Europeans as noted by DuBois, Diop and Boule & Vallois.
Again another piece of incontrovertible scientific evidence that the Paleolithic Europeans were Blacks. The skeletal remains of these people as noted by Boule and Vallois recalled the tropical African type.
“So striking” writes Professor Elliot Smith, “is the family likeness between the early Neolithic peoples of the British Isles and the Mediterranean and the bulk of the population, both ancient and modern, of Egypt and East Africa, that the description of the bones of an Early Briton of that remote epoch might apply in all essential details to an inhabitant of Somaliland. (The Ancient Egyptians, p. 58.)
Geneticist Peter Underhill refines the facts: About 80 percent of Europeans arose from primitive hunters who arrived about 35,000 years ago, endured the long ice age and then expanded rapidly to dominate the continent, a new study shows.
Researchers analyzing the Y chromosome taken from 1,007 men from 25 different locations in Europe found a pattern that suggests four out of five of the men shared a common male ancestor about 40,000 years ago.
The basic pattern had some changes that apparently developed among people who once shared a common ancestor and then were isolated for many generations.
This scenario supports other studies about the Paleolithic European groups.
Those studies suggest that a primitive, stone-age human came to Europe, probably from Central Asia and the Middle East, in two waves of migration beginning about 35,000 years ago.
Their numbers were small and they lived by hunting animals and gathering plant food. They used crudely sharpened stones and fire.
“About 24,000 years ago, the last ice age began, with mountain-sized glaciers moving across most of Europe.
The Paleolithic Europeans retreated before the ice, finding refuge for hundreds of generations in three areas: what is now Spain, the Balkans and the Ukraine.
“When the glaciers melted, about 16,000 years ago, the Paleolithic tribes resettled the rest of Europe. Y chromosome mutations occurred among people in each of the ice age refuges.
About 8,000 years ago a more advanced people, the Neolithic, migrated to Europe from the Middle East, bringing with them a new Y chromosome pattern and a new way of life – agriculture. About 20 percent of Europeans now have the Y chromosome pattern from this migration [African Y chromosome E3b and SouthWest Asian J].

Song stuck in my head: Ito by SID
Last thing you googled: urgent care near me (I think I cracked a rib and need it checked out)
Time: dinner, I only had lunch today
Dream trip: traveling across the world, jumping countries (kinda did this over the summer, but I’d love to do it again with more countries)
Last thing you read: Skin a natural history, by Nina Jablonski (she’s a family friend of a family friend and is giving a talk at my college next week)
Last book you enjoyed reading: Dragon Empire by R F Kuang. The Poppy War is a good series
Favorite thing to cook/bake: I love making piroshki, a Russian hand pie. I also like making chocolate covered candied orange peels but those are labor intensive
Favorite craft to do in your free time: crochet and knit depending on the state of my hands
Opinion on circuses: the history is fascinating, but dark. I love the human feats but fuck animal abusing groups. I know a number of jugglers and acrobats, so I love watching that stuff but there is also a long history of exploitation
Most niche dislike:
Do you have a sense of direction: yes. I’m often in charge of navigation and will give directions on the spot. I also got around entirely new cities and countries on my own without problem this past summer, as well as knowing the general location of where I am at most times
Tagging: @error404-welp @ofbooksandstardust and @beeyonkuh

The Evolution and Meanings of Human Skin Color | Nina Jablonski
Variation in human skin color has fascinated and perplexed people for centuries. As the most visible aspect of human variation, skin color has been used in the past as a basis for classifying people into “races.” In this lecture, Leakey Foundation grantee Nina Jablonski discusses the evolution of human skin color and how color-based race concepts have influenced societies and impacted social…
