3. Farming’s effect on the Homo sapiens skeleton
Gradual decline in mobility with the adoption of food production in Europe
Christopher Ruff et al.
PNAS, July, 2015 (Vol. 112, pg. 7147)
1,842 European skeletons spanning 33
kyr, Upper Paleolithic to 20th century
Decreased bending strength implies a
decline of mobility as agriculture came to
dominate how people produced food.
The original decline in mobility was more
important than subsequent changes in
farming technology.
http://www.pnas.org/content/112/23/7147.abstract
Decreased bending strength of leg bones
accompanied the shift. The trend was
not apparent during the last 2 ka, as
agriculture became more mechanized.
From the Neolithic to Roman eras (7-
2 ka) humans shifted from mobile to
an increasingly sedentary lifestyles.

The study measured the strength of the tibia,
femur, and humerus. The authors found little
change in mediolateral, or side-to-side, bending
strength in all the bones over time, but a decline in
anteroposterior, or front-to-back, bending strength
of the tibia and femur beginning in the Neolithic
Period (7 ka), and continuing through the
Iron/Roman Period (2 ka).
The results suggest that mild changes in
activity levels may be insufficient to
stimulate changes in bone mass and that
vigorous exercise may be required to
increase bone strength.

4. 15 ka, all humans lived by foraging wild animals
and plants. Exploiting such resources worked best
when people lived in tiny bands and moved
around a lot. Individual foragers could not build
much wealth or power. They tended to be very
poor but very equal.
SoL: $1.10 per day (1990 values)
12 ka, foragers numbered 6 million
11 ka, population exploded with farming
2 ka, farmers numbered 250 million
By 1800 AD, foraging was almost extinct
With farming, big social groups stayed in one place
working their fields. They flourished at the expense
of smaller, less sedentary ones. Farmers were
typically richer than foragers
SoL: $1.50-$2.20 per day
Farming’s effect on wealth distribution
To each age its inequality
Ian Morris
New York Times, July 9, 2015
Farming needed more complicated divisions of
labor than foraging. Some people became
aristocrats or godlike kings; others became
peasants or slaves. Economic inequality surged.
5. Exotic objects of the European Neolithic
Signs of Wealth: Inequalities in the Neolithic
National Museum of Prehistory, Les Eyzies
June 27 to November 15, 2015
As Neolithic communities dispersed into
Europe, 8-4.2 ka, they brought new
techniques for making and ornamenting
material culture. Intricate manufacturing
could produce very beautiful pieces.
High-value items usually signified wealth
and distinction for the owner. Some were
hoarded to be used in relations between
the elites or with supernatural powers.
High-value items often featured exotic raw
materials, some traveling hundreds of
kilometers from quarry to workshop.
Likewise, finished pieces, including
necklaces, daggers, axes, bracelets, could
circulate for long distances and times.
Signs of Wealth features "object sign"
artifacts in exotic materials still valuable in
our day (jade, gold, turquoise, jet, etc).

Discovered June 2014 at the Grotte du
Bison at Arcy-sur-Cure in Burgundy,
France. from the left femur of an adult
reindeer 60-55 ka.
Evidence of meat butchering and bone
fracturing to extract marrow are evident
on the tool.
Percussion marks suggest the use of the
bone fragment for carved sharpening
the cutting edges of stone tools.
Chipping and a significant polish show
the use of the bone as a scraper

missing connection between African

L-R: Neanderthal, Manot cranium, modern human
55,000-year-old skull, Manot Cave
The distinctive bunlike shape at the base of the skull
resembles modern African and European skulls but
differs from other anatomically modern humans from
the Levant, and is thus a strong clue that these were
among the first humans to settle Europe,
Manot 1 calotte is of a fairly small adult
individual, sex undetermined.

12. La Chapelle-aux-Saints burial evidence
Evidence supporting an intentional Neandertal burial at
La Chapelle-aux-Saints
William Rendu, et al.
PNAS 15 November 2013
A Neandertal burial was recognized in 1908
in the bouffia Bonneval, at La Chapelle-aux-
Saints (France). New research indicates that
the body was deposited in a pit dug by other
members of its group and protected by a rapid
covering from any disturbance.
the discovery of skeletal elements belonging to
the original La Chapelle aux Saints 1 individual,
two additional young individuals, and a second
adult in the bouffia Bonneval highlights a more
complex site-formation history than previously
proposed.
These discoveries attest the existence of West
European Neandertal burial and of the
Neandertal cognitive capacity to produce it.

14. Neandertal demise
Neandertal Demise: An Archaeological
Analysis of the Modern Human
Superiority Complex
Table 1. Hypotheses for the demise of Neandertals (Hn) and rise of modern humans (Hs)
Paola Villa, Wil Roebroek
PLOS One, April 2014
http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0096424#pone-0096424-t002
Hn and Hs archaeological records are not different
enough to explain Hn demise in terms of inferiority.
Interbreeding and assimilation may have hastened the
disappearance of Hn morphology.
1. Hs had complex symbolic communication systems and fully syntactic language, while Hn did not.
2. Hn had limited capacity for innovations.
3. Hn were less efficient hunters.
4. Hn weaponry was inferior to Hs projectile technology.
5. Hn had a narrow diet, unsuccessful in competition with Hs with their more diverse diets.
6. Hs exclusively used traps and snares to capture animals.
7. Hs had larger social networks.
8. Hs groups entering Europe were significantly larger than regional Hn groups.
9. Hs tool hafting is indicative of modern cognition; Hn hafting was simple (used naturally available glues).
10. Hn decline was related to cold climate ~40 ka.
11. Hn extinction was related to the eruption of the Mt. Toba volcano (Sumatra, 74 ka).

16. Women’s body shapes
Curvology: The Origins and Power of Female Body Shape .
David Bainbridge. Granta; 227 pages
it makes evolutionary sense for new couples to plump
up—in comparison with when they were single—as this
provides both of them with a fatty fallback for when they
begin the arduous task of reproducing the species
curvy bums and boobs ensure the future of humankind.
They are proof that a woman was well-nourished while
growing up and carries good child-feeding genes
Episodes of bingeing and starvation
were normal features of pre-
agricultural life; some animals still
reduce their intake in winter. Eating
disorders, the author writes, could
be “evolutionary relics of a time
when our food supply was
unpredictable
