Module 10 (HS6) - HORTICULTURAL SOCIETIES
0. OBJECTIVES
In this module you will learn:
-
the current view on the causes of the first switch
from hunting & gathering to plant cultivation (horticulture) around
8,000 BC
-
the causes of the invention of metallurgy as a
consequence of the shift to horticulture
-
how five distinctive characteristics of horticultural
societies are causally interrelated and ultimately derived from horticultural
technology
-
how the adoption of horticultural technology has
caused vast expansions of some populations ("demic expansions") several
times during the long course of human history, leading to intensive episodes
of intersocietal selection, including the Bantu expansion, the Austronesian
expansion, and possibly the Indo-European expansion
-
how the emergence of horticulture in the New World
represents a natural test of ecological-evolutionary theory
1. INTRODUCTION
Horticulture (from Latin hortus
= "garden") - animal husbandry and plant cultivation without the plow,
using the hoe and the digging stick.
The first horticultural societies appeared
ca. 8,000 BC.
This type of farming is also called "swidden"
and "slash-and-burn" farming.
2. CAUSES OF THE EMERGENCE OF HORTICULTURAL
SOCIETIES
Contemporary view is that human societies were
forced to (rather than chose to) shift from foraging to horticulture
and animal husbandry around 8,000 BC because of environmental depletion
caused by progress in hunting technology combined with global warming (making
plant cultivation possible) following the end of the last ice age.
Q - What are the causes of the emergence of
horticultural societies? Is increasing human intelligence one of
them?
3. INVENTION OF METALLURGY
The invention of metallurgy (first copper, and
later bronze) marks the transition from simple to advanced horticultural
societies.
The invention of metallurgy may have been
ultimately caused by the adoption of horticulture, following a long chain
of causes and effects.
Q - Is it reasonable to argue that a principal
indirect cause of the invention of metallurgy was the more sedentary lifestyle
associated with horticultural technology?
4. CHARACTERISTICS OF HORTICULTURAL SOCIETIES
Horticultural technology can be viewed as the
primary cause of some of the common characteristics of horticultural societies.
These include:
-
cultivation primarily a female responsibility
-
high incidence of matrilineality
-
high incidence of warfare
-
high incidence of ancestor worship
-
high incidence of slavery
These characteristics may be causally
interrelated as shown in the next exhibit:
The following sections look at some of the empirical
evidence for common features of horticultural societies.
1. Cultivation by Women
Compared to agrarian societies (using plow technology), cultivation in
horticultural societies is more often carried out by females.

Q - How would one describe the division of
labor between the sexes in horticultural societies with respect to plant
cultivation? Plant cultivation tends to be ... primarily men's work,
shared equally by both sexes, primarily women's work?
2. Matrilineality
Matrilineality - the tracing of descent
through the maternal line (NOTE: matrilineality is not the same
as matriarchy!)

4. Ancestor Worship
Ancestor worship is related to the central role
of kinship based on clans (= extended kin groups).
5. Slavery
Slavery is especially common among
horticultural societies.
Q - Which of the following items of culture
are more likely to be present in a horticultural society than in a hunting
& gathering society, or vice-versa? Which ones are no more likely in either type of society?
-
children trained to be independent and self-reliant
-
ancestor worship
-
art and religion
-
warfare
-
ceremonial cannibalism
-
sharing
-
slavery
-
private ownership of land
-
it is profitable to conquer other societies
-
animism
-
games of strategy
5. THE ROLE OF HORTICULTURE IN MAJOR POPULATION
MOVEMENTS & INTERSOCIETAL SELECTION
1. The Diffusion of Indo-European Languages
in Europe and Asia
In 1767, James Parsons noted similarities among
numerals of several European languages, which he called "Japhetic".
In 1796, Sir William Jones, Chief Justice of India, postulated a common
origin for Greek, Latin, and Sanskrit on the basis of the similarities
he observed between these languages.
Later research indicated that many languages
spoken in Europe and parts of Asia are descendent from a common ancestor
language called (proto-)Indo-European (PIE).
A new and controversial hypothesis due to Colin
Renfrew (1987. Archaeology and Language: The Puzzle of Indo-European
Origins. Cambridge University Press) is that Indo European languages
expanded from Anatolia into Europe together with horticultural technology
beginning some time around 6,000 BC. The traditional view places
the expansion much later, around 3,500 BC (see Mallory,
J. P. 1989. In Search of the Indo-Europeans: Language, Archaeology
& Myth. London: Thames & Hudson.)
Renfrew's theory (borrowed from Ammerman &
Cavalli-Sforza) is that Indo-European languages and horticultural technology
spread together as a "population wave of advance" caused by the higher
population density allowed by horticultural technology compared to
H&G technology.

Q - According to Colin Renfrew, what mechanism
is ultimately responsible for the spread of Indo-European languages in
Europe?
Renfrew's theory is controversial.
Many archeologists today prefer an older theory originally proposed
by V. Gordon Childe and identified today with the work of Maria
Gimbutas. According to this view PIE speaking populations
expanded from an area situated north of the Black Sea (in today's
Ukraine) around 3,500 BC. The decisive technological advantage
facilitating the expansion were domestication of the horse and
perhaps the invention of animal-drawn wheeled vehicles.
2. The Bantu Expansion in Africa
A similar episode of "demic expansion" based on
advance in subsistence technology has been documented in the case of the
Bantu expansion in Africa, from about 3,000 BC to 500 AD. This historical
episode has been reconstructed on the basis of genetic and linguistic data
by Luigi Luca Cavalli-Sforza et al. (1994. The History and Geography
of Human Genes. Princeton University Press.) and is also discussed
in Jared Diamond's Guns, Germs, and Steel.
3. The Austronesian Expansion in the Pacific
The expansion of Austronesian-speaking populations
took place from about 3,500 BC to 1,300 AD from a center on the South China
coast and Taiwan over the whole Pacific ocean and west all the way to Madagascar
near the coast of Africa.
4. Demic Expansions and Intersocietal Selection
In a recent article Diamond and
Bellwood (2003) discuss a number of additional episodes of
linguistic expansion resulting from the adoption of farming.
From the point of view of
ecological-evolutionary theory used in this course, these
historical episodes constitute instances of intersocietal
selection, in which hunting and gathering societies are
destroyed (or displaced) by the expansion of technologically
more advanced horticultural societies.
The next exhibits (repeated from
Module 7) show the remarkable
similarities between 3 theoretical models of the broad patterns of history:
-
Luigi Luca Cavalli-Sforza's model of demic expansions
-
Jared Diamond's model of the broadest pattern
of history
-
Gerhard Lenski's model of intersocietal selection
These models are illustrated in the
following exhibits
6. THE EMERGENCE OF HORTICULTURE IN THE
NEW WORLD
The first human settlements in the New World occurred
50K BP to 13K BP, through the land bridge at the Bering Strait (between
Siberia & Alaska). After the last glaciation, the land bridge
was submerged and the New World cut off from the Old World. These
circumstances constitute a "natural experiment", since cultural diffusion
was thereby precluded so that horticultural technology could not have diffused
from the Old World. Nevertheless, horticulture emerged independently
in the New World.
The independent emergence of horticulture in
the New World suggests that:

Q - What does the independent emergence of
horticulture in the New World suggest?
