Q

who developed natural selection?

A

What is natural selection?
• Developed by Darwin and Alfred Russel Wallace
• Both observed that species varied over time and space
Similarities between distinct species can be explained by common ancestry

42
Q

why did darwin propose natural selection?

A
  • Darwin proposed natural selection, or descent with modification, as a mechanism for evolution
    • Variation, not a unitary essence, is the central condition of life
43
Q

what is population thinking?

A
  • population size is limited by the availability of resources.
    • variants within a species respond differently to environmental challenges, and only some will be successful, survive, and reproduce.
44
Q

what 3 principles is darwins theory of evolution based on?

A
  1. Variation: No two individuals of a species are identical. 2. Heredity: Offspring resemble their parents.
  2. Natural Selection: Different variants leave different numbers of offspring
45
Q

what is pangenesis?

A

• Pangenesis was a theory of heredity favored by Darwin and others heritable info is in gametes

46
Q

what were mendel’s experiments?

A

: bred pea plants. Showed that traits passed down can be dominant or recessive

47
Q

what is mendelian inheritance?

A

Mendelian inheritance views heredity as based on non-blending, single particle inheritance.

48
Q

emergence of genetics

A

• The emergence of genetics: the scientific study of biological hereditary
Emerged in early 1900s, 35 years after Mendel’s work

49
Q

what are genes?

A

• Genes are the biological unit of heredity
• Genes are portions of DNA molecules that code for proteins responsible for phenotypic traits
• Several forms of a given gene are called alleles
Chromosomes are in the nucleus of cells that contain DNA and genes

50
Q

what can happen with mutations?

A
  • New alleles can only be formed through mutation
    • Caused by the alteration of the portion of DNA where the gene is found
    • Results in variation and is necessary for natural selection to occur
51
Q

what is norm of reaction?

A

• Norm of reaction predicts the possible phenotypic outcomes of genotypes in different environments

52
Q

what is niche construction?

A

• Organisms can also affect their environments through niche construction, which in turn creates selective pressures.

53
Q

what is microevolution?

A

• Microevolution: Short term evolutionary changes that occur within a species over a few generations of ecological time (time involved in adapting to ecological settings)

54
Q

what is macroevolution?

A

long term evolutionary changes, including the origin of new species and diversification over space and millions of years of geological time.

55
Q

what does population genetics involve?

A

Population genetics: involves the statistical analysis of short term evolutionary change in large populations

56
Q

how is gene frequency measured?

A

measured by calculating the occurrence of particular alleles in a populations gene pool, the totality of the genes of a given population or species

57
Q

what is cline?

A

• Cline refers to the gradual shift in the distribution of phenotypes between populations over space, as alleles increase or decrease in frequency.

58
Q

why is the concept of race biologically meaningless?

A
  • More genetic variation found within so called races than between them
    • Distribution of some traits does not match the distribution of others (skin color and hair type)
    • Uv + folate aren’t the only reasons skin color varies
59
Q

what four processes cause shifts in gene frequency?

A

Ø Natural selection
Ø mutation
Ø Gene flow
Ø Genetic drift

60
Q

when does gene flow occur?

A

• Gene flow can occur with the in-migration of another population of the species and involves the exchange of genes between overlapping gene pools.

61
Q

what does genetic drift involve?

A

• Genetic drift involves random changes in the frequency of certain alleles.
Has relatively small effect on large, stable populations

62
Q

bottleneck vs founder effect

A

The bottleneck effect is populations that are suddenly reduced in size due to disease and disaster
Founder effect is a small group breaking off from the group

63
Q

what does acclimation involve?

A
  • Acclimation involves a change in body function due to environmental stress
    • They can be short term, such as shivering to maintain body temp
64
Q

what assumption were IQ tests based off?

A
  • IQ tests were developed on the assumption that they could provide a reliable measure of intelligence
    • Variations in IQ scores reflect differences in social class, culture, and education
    • Students of different racial backgrounds
65
Q

what is the genome wide association study?

A

• Genome wide association study- studies that aim to identify low side throughout the genome associate with an observed trait or disorder

66
Q

what is anthropomorphism?

A
  • Modern primates share part of their evolutionary history with humans
    • Anthropomorphism: the attribution of human characteristics to non-human animals

69
Q

evolutionary trends that developed with the divergence of the earliest primates?

A

• Increase in brain size relative to body size along with increased complexity of the neocortex

72
Q

what is the arboreal hypothesis?

A

• Arboreal hypothesis: primate features are a result of adaptation to living in trees

73
Q

what is the visual predation hypothesis?

A
