Transcript of Intro #7
Acquired Characteristics and Darwin, and environmental change
that help the animal survive
more likely to survive
these characteristics to next generation.
the "cheater" gene
The brain evolving:
Biology sets the stage for the development to be learned.
Species Typical Behaviors,
3. Your brain’s natural “save” button.
It’s a shocking, impressive, or surprising moment that is so moving and memorable, it grabs the listener’s attention and is remembered long after the presentation is over. When your brain detects something new or unexpected, the amygdala releases the neurotransmitter dopamine, which acts as your brain’s natural “save button.” Dopamine creates a heightened state of emotion that makes it more likely your audience will remember your message and act on it.
Bipedalism = walking
Encephalization = brain development
Language = pass info to next generation
a lot of these mutations in brain cells building on each other
as an example of human species-specific behavior
6 universally recognized expressions/emotions, so innate
Humans are biologically prepared to learn
The cultural differences in expression are learned
Instinctual drift = drifting back to instinct
POLAR BEARS KILL A CHILD AT PROSPECT PARK ZOO
By JAMES BARRON
Published: May 20, 1987 New York Times
Two polar bears mauled and killed an 11-year-old boy who climbed a fence at the Prospect Park Zoo in Brooklyn with two friends last night and then sneaked into the polar bear enclosure
This was at a zoo in Berlin
Differential parental investment theory
That we are picky about choosing a mate because it is an investment in our role as parents.
Human Mating Patterns
All human cultures have some degree of monogamy expected, but this can vary.
2-10% of children are biologically fathered by someone other than the social father.
survival of the fittest
= that genes determine behavior.
= that biological evolution (natural) can be applied to cultural evolution (social).
