Q

flight distance

A

when dogs percieve something as fearful its when they start to run and the distance they do so. the shorter the flight distance the more likely you are to survive

Q

how do teleology and natural selection differ as explanations of evolutionary change?

A

teleology believes there is a purpose in nature in which species evolve to a higher form, where natural selection believes species survive environmental changes due to genes that are more successful

Q

how are black moths and dark skinned humans explained by natural selection

A

the moths are darker colors survived because they could blend in better with trees. the darker skin is essential for survival when living close to the equator

Q

how is natural selection differnt from learning?

A

natural selection describes how whole species adapt and change. the learning process is also about change, but changes in behavior, though pattern and emotional reactions. learning is at an individual level rather than at the species level

Q

what do selective breeding experiments tell us about genetic effects on learning

A

learning has a genetic component and can be strengthened by selective breeding

17
Q

When we compare the IQs of identical twins reared together versus identical twins reared apart, what do we find? What does this tell us about the genetic influences on learning?

A

Identical twins are likely to have similar IQ scores, whether or not they are raised together. That means there is a huge genetic component to learning

18
Q

Why do adopted children have IQs that more closely match their biological parents rather than their adoptive parents? What does this finding tell us about the genetic component to learning

A

The genetic component is stronger than the biological component when referring to learning

19
Q

what are some of the prenatal and postnatal conditions that tend to reduce learning ability

A

pre: neurotoxins, disease, and malnutrition
post: neurotoxins and head injuries

20
Q

give some examples of learned behaviors in animals and children that seem to reveal a critical period. what do these behaviors suggest about the relationship between nature and nurture

A

children have brains that are biologically dispositional to learn, but there is a critical period in which it takes place. human maternal behavior and social behavior in dogs

21
Q

what is the relationship between brain capacity and primate evolution from the early protohumans to modern humans

A

Brain capacity increased with the evolution of primates. As the primates evolved so did the size of the frontal lobe and temporal lobe (frontal lobe: organization, planning) (temporal lobe: language)

22
Q

Why do theorists think that the use of tools is such an important milestone in the evolution of modern humans? What events probably prepared the way for tool use

A

It’s a milestone because it gave humans a big survival advantage. Standing erect and loss of body hair definitely aided in the survival advantage, humans were becoming more intelligent

23
Q

What is the presumed relationship between social cooperation and intelligence? How do researchers think that social cooperation evolved in the human species?

A
  • Social cooperation in terms of group hunting, required language, use of tools, which both require intelligence.
  • Researchers believed it evolved because the ones without language, knowledge about tools, and lastly intelligence did not live to procreate, so they died off
24
Q

What is it about the evolution of language that seems to parallel language acquisition in children

A

Both start off with forms of vocalization which evolved in to signs and signals. Those turned into holophrastic signs, one word sentences. They equally grew from one simple step to the next, with the help of brain capacity

25
Q

Many philosophers believe that humans are uniquely different from other animals. What can humans do that other animals cannot

A

Humans have the ability to contemplate god and create religion

26
Q

What do the Belyav experiments on foxes in Siberia suggest about the possible evolution of the dog

A

That when you selectively breed an animal for their tameness and their coloring their whole genetic make up is affected and also that the evolution from wolves to dogs could have taken place quickly

27
Q

How did the wolf evolve into the modern dog according to evolutionary scientists

A

It’s skull, brain and body become smaller, it’s snout shorter, and its teeth changed from killing to non-killing

28
Q

How does evolution theory explain the human penchant for myth, ritual, and religion

A

People who engaged in activities surrounding myth ritual and religion would be healthier and stronger, which would mean they are more likely to survive. (ex: meditation calms the autonomic nervous system, reduces stress, and promotes good health.)
