Genes: Their Location and
In the nucleus of every cell we have 46 chromosomes……
The science that seeks to explain why
humans act the way they do
Focused on how evolution has shaped
the mind and behavior.
Explaining Universal Behaviors
Evolutionary psychology seeks to reconstruct problems that
our ancestors faced in their primitive environments, and the
problem-solving mechanisms they created to meet those
From these reconstructed problem-solving adaptations, the
science then attempts to establish the common roots of our
ancestral behavior, and how those common behavioral roots
are manifested today in the widely scattered cultures of
The goal is to understand human behavior that is universally
aimed at the passing of one's genes into the next
Natural Selection at Work
•1959 Russian Fox story
•40 Males, 100 Females- mated-then
kept only tamest of bunch.

•As a result of selective
breeding, the new foxes
became tamer and more dog-like.
Evolutionary Psychology at Work
•If we wanted to create a whole population of brainy
teachers, we could take some brainy teachers & have them
•Then have the brainiest offspring mate amongst each
other, and for countless generations keep doing the same
•After 200 years, what would the population be like or what
are the chances that the 40th generation of offspring be

Sexuality and the Evolutionary

• When average men

men agreed, almost
no women agreed.
How Much Credit ( or Blame )
Do Parents Deserve?

up in the same environment,
are you all the same?
•Parents effect your belief
systems and values much
more than your personality.
•Parents take too much
credit for success and too
much blame for failures.
can be VERY dangerous,
Lets look at perhaps our first environmental influence….
What does this mean for humans?
• If children from impoverished
environments given stimulating infant
care, they score better on intelligence
tests by age 12 than counterparts.
