Lecture 8/9 Evolution

Question 1

Anthropology

Answer 1

The study of man

Question 2

Why do we think organisms evolved?

Answer 2

This goofy guy named Charles Darwin

Question 3

What are Genes?

Answer 3

A unit of heredity which is transferred from the parent to offspring, which determines some characteristic of the offspring

Question 4

EVOLUTIONARY THEORY

Answer 4

Attributes that increases chances of
survival and reproduction of genes are
more likely to be passed down to
offspring

Question 5

Three conditions that need to be present for evolution to occur

Answer 5

• Variation in Species
• Inheritance of traits
• Change in environment that favor some
  traits over others

Question 6

VARIATION IN SPECIES

Answer 6

Two members of the same species could
have different genes and hence different
traits

Question 7

INHERITANCE OF TRAITS

Answer 7

You get traits (which are genetic) from your parents

Question 8

ADAPTATION

Answer 8

Evolutionary processes that leads to changes in species that increases fitness and survival

Question 9

THE PROCESS OF EVOLUTIONARY ADAPTATION

Answer 9

1. Change in environment
2. Breeding across different species
3. Genes are passed down to offspring
4. Species that are more likely to survive
   are more likely to pass genes to
   offspring

Question 10

What does “Survival of the Fittest” mean?

Answer 10

The better adaptations makes it more likely that animal survives and produce offspring, based off of environment

Question 11

What is Sexual Selection?

Answer 11

basically how hot the person looks

Question 12

MATE SELECTION IN For male people

Answer 12

Men should be most attracted to women who have
genetic traits that can produce and raise children

Question 13

MATE SELECTION IN For Female people

Answer 13

Women should be most attracted to men who can
provide resources to raise offspring

Question 14

ARTIFICIAL SELECTION

Answer 14

When the trait is so useful owners selectively breed them

Question 15

ENVIRONMENT OF EVOLUTIONARY ADAPTATION

Answer 15

The period of time during which, many
human psychological mechanisms are
believed to have evolved.

Question 16

The Cerebral Cortex evolved at a _____ ____ than other parts of the brain

Answer 16

Later stage

Question 17

The cerebral cortex is hypothesized to have evolved at around the same time of the environment of ____ ____

Answer 17

evolutionary adaptation

Question 18

3 EVOLVED PSYCHOLOGICAL MECHANISMS

Answer 18

• A cognitive system produced by multiple parts (neurons and stuff)
• Activated only within specific environmental
  contexts (threat detection, mate selection, etc.)
• Environment context facilitates cognitive
  processes and a behavior (seeing a snake => stuff happens in your brain)

Question 19

Threat superiority Effect

Answer 19

The observation that people pay more attention to
possible threats than to other stimulus or events in
their environment.

Question 20

THREAT DETECTION MODULE

Answer 20

A Darwinian module that evolved to detect threats
*Detects stimulus in the environment that threatens
survival of the organism
