Paternal Investment Theory

Thanks Tony

 

> Modern races were formed by isolation and adaptation to local conditions,
the most powerful of which is climate. Intellectual adaptations that allowed
early humans to survive long, cold ice-age winters were vastly different
from those sufficient to sustain existence in a tropical climate, rich with
year-round nourishment. These adaptations appear not only in external
physical differences but in dramatically different IQ profiles, and in
traits such as foresight, altruism, mating fidelity, anxiety, diligence,
thriftiness, etc.
>
> Philippe Rushton has used life history theory to explain such adaptations
(see full treatment of this theory in AR, Dec. 1994). Citing Edward O.
Wilson, the father of sociobiology, he explains:
>
> "Evolutionary biologists assume that each species (or subspecies, such as
a race) has evolved a characteristic life history adapted to the particular
ecological problems encountered by its ancestors. A life history is a
genetically organized suite of characteristics that evolved in a coordinated
manner so as to allocate energy to survival, growth, and reproduction. These
strategies may be organized on a scale.
>
> "At one end are 'r-strategies' that emphasize gamete production, mating
behavior, and high reproductive rates and, at the other, 'K-strategies' that
emphasize high levels of parental care, resource acquisition, kin
provisioning, and social complexity. The K-strategy requires more complex
nervous systems and larger brains . . . . [A]rchaic versions of what were to
become the modern Caucasoid and Mongoloid peoples dispersed out of Africa
about 100,000 years ago and adapted to the problem of survival in
predictably cold environments. This evolutionary process required a
bioenergetic tradeoff that increased brain size and parenting behavior ('K')
at the expense of egg production and sexual behavior ('r')."

> Edward Miller has proposed a concept called paternal investment theory. He
suggests that "in cold climates males were selected for provisioning, rather
than for mating success. In warm climates, where female gathering made male
provisioning unessential, selection was for mating success. Male-hunted meat
was essential [in cold climates] for female winter survival. Genes that
encouraged mating success were selected for in warm climates. Negroes
(blacks) evolved in warm climates, while Caucasians (whites) and Mongoloids
(Asians) evolved in colder climates. Mating is assisted by a strong sex
drive, aggression, dominance, sociability, extroversion, impulsiveness,
sensation seeking, and high testosterone. Provisioning is assisted by
anxiety, altruism, empathy, behavioral restraint, gratification delay, and a
long life span."

Genes that encouraged mating success were selected for in warm (was cold)
climates. Negroids (blacks) evolved in warm cold climates, while Caucasians
(whites) and Mongoloids (Asians) evolved in colder climates. Mating is
assisted by a strong sex drive, aggression, dominance, sociability,
extraversion, impulsiveness, sensation seeking, and high testosterone.
Provisioning is assisted by anxiety, altruism, empathy, behavioral
restraint, gratification delay, and a long life span. Explanations are
offered for racial differences in many personality characteristics, hormone
levels, monamine oxidase levels, testosterone levels, lactase dehydrogenase
metabolic paths, life spans, prostate cancer rates, hypertension, genital
(penis and testes) size, vocal frequencies, liver size, muscle structure,
mesomorphy, bone density, sports performance, crime rates, rape, child
abuse, earnings, age at first sexual activity, AIDs, illegitimacy, divorce,
marriage, and polygyny rates. Eye color correlations are discussed. Negro
family structure in the Caribbean and the U.S. may reflect selection in
Africa during hunter-gather times. Comparison is made with differential K
theory and father absence theories.
