Q

Natural Selection

A

A slow process where nature selects which genes that have randomly occurred in a species to carry on in their offspring. The genes that are selected are the ones that helps a species survive in their particular environment.

Q

Synthetic Theory of Evolution

A

Extension of Mendelian genetics and Darwinism. Formal study of how gene pools of different species change and diversify over time which leads to the formation of new species and how they came to be.

37
Q

Allele

A

How a gene is expressed. The characteristic or version of a gene. Green or yellow or wet and dry.

38
Q

Gregor Mendel

A

Discovered gene inheritance is not like blending paints

39
Q

Inheritance of Acquired Characteristics

A

Lamarck said if a species’ offspring becomes blended then they can gain or lose traits they gain from their lifetime and pass that onto their offspring (incorrect theory)

40
Q

Blending Inheritance

A

Offspring is a blend of both parents and has a different set of genes.

41
Q

Anatomical Variation

A

Variation of physical traits

42
Q

Why can’t we use blood to study evolution?

A

Because the blood type between species can be very similar but in reality be very different if you compare their physical traits

43
Q

What’s the hierarchical structure of evolution?

A

Evolution works on a molecular and physical and anatomical level

44
Q

What does it mean to be between vs within the gene?

A

Between-comparing 2 different types of genes.
Within-comparing the same type of genes

45
Q

What does genetic variation measure?

A

Measures how long ago a species diverged

46
Q

What does anatomical variation measure?

A

Measures the physical traits that showcase physical adaptation

47
Q

Gene Flow

A

Genetic contact between populations which increases similarities between populations. Ex: immigration

48
Q

Genetic drift

A

Random changes to the gene pool which make certain populations genetically different from other populations. They can’t reproduce with each other anymore.

49
Q

Phenotype

A

Specific variation in genes that cause changes in physical appearance

50
Q

Mendelian Inheritance

A

Explains how genes are inherited and passed on to offspring

51
Q

Who created the synthetic theory>

A

Theodosius Dobzhansky, Ernst Mayr, and George Gaylord

52
Q

What’s synthetic theory?

A

Combination of Darwin’s theory and mendalian genetics that explains through genetic changes over time a new species is formed

53
Q

Genetic Variation

A

Differences of DNA among individuals

54
Q

Ramapithecus

A

David Pilbeam discovered that a 14 million fossil (discovered to be part of the orangutan lineage) which caused scientists to question the age of humans

55
Q

Genetic/molecular evolution

A

Used to track time

56
Q

Adaptative Divergence

A

Species that have a common ancestor but then split apart due to various adaptations to the environment

57
Q

Mutations

A

Copying errors of the DNA which cause variations of the DNA. They don’t always have an impact but some do have a negative or positive effect which gets copied to the next offspring or not.

58
Q

What if you compare dna of two different species versus two genes of two different species?

A

DNA-differnet among species
Genes-similar among species

59
Q

What does genetics track vs anatomy?

A

Genetics tracks time while anatomy tracks adaptation

60
Q

What does population genetics not explain?

A

The ineraction between species and how they evolve

61
Q

What type of extinction matches Darwin?

A

Background extinction

62
Q

WHat causes one species to have a bigger population than another?

A

Species selectoin
Ecoologies and histories

63
Q

What happens if a genetic mutation is neutral?

A

It will hardly spread throughout the population because it hardly has an effect

64
Q

Human Genome Project

A

The production of a complete DNA sequence of a human cell in hopes that it would reveal how human bodies are built and how to cure them when human bodies are built poorly

65
Q

Stephen Jay Gould

A

Scientist who went beyond population genetics

66
Q

Evolutionary Synthesis

A

Claims how the combination of Darwin’s evolution with Mendalian genetics explain the entire process of evolution as a whole

67
Q

What are the two types of Extinction?

A

Background and Mass extinctions

68
Q

Background Extinctions

A

If one species is better than another the other will become extinct. Reflects balance of nature–species go extinct and others take their place

69
Q

Mass Extinctions

A

During an ecological disaster, many species from different lineages die off at the same time. Survival of the luckiest. When a species competitor dies off, the survivors can divide the ecosystem among themselves.

70
Q

What do genes not have?

A

They cannot explain how many organisms of a species one should produce

71
Q

Species Selection

A

Higher order process that creates competiton between species

72
Q

Why are species constantly unstable?

A

They’re constantly unstable because they’re constantly changing to their environment

73
Q

What is the other viewpoint of species changing?

A

Niles Eldredge said species only change when necessary

74
Q

Punctuated Equlibria

A

Gaps in closely related fossils

75
Q

Evo-devo

A

Intersection of evolutionary and developmental biology. How change in form and shape arise.

76
Q

Plasticity

A

When the genetic phenotype (interaction of genes with the environment) changes due to the environment. A varation occurs.

77
Q

Canalization.

A

Opposite of plasticity. When genes interact with the environment and stay the same. A variation that doesn’t change over time also becomes normal.

78
Q

Epigenetic

A

How the environment can affect the way your genes work. The actual genes don’t change but they way they function does.

79
Q

Niche Construction

A

How an organism will change its environment to suit its own needs. This helps the organism to adapt and can also affect other organisms in the same environment

80
Q

Why is science political?

A

Because you can’t talk about people apolitically

81
Q

Scientific Racism

A

Using science for political racist reasons

82
Q

Are we all biased studying anthro?

A

Yes no matter how objective we try to be

83
Q

Are humans born or made?

A

Both-your genes do affect you but your social and cultural lineage will also play a role in how you turn out. But also, humans have agency in how they want their life to turn out.

84
Q

Eugenics

A

20th century movement that created a set of beliefs and practices to improve the human genetic condition. Imoral.

85
Q

Hereditarianism

A

The idea that the creature is made not born. Our fate is in our genes. Problematic.

86
Q

Human Genome Project-why did it turn out badly?

A

Because people were using it as an excuse to be immoral because they thought they could better the human genetic condition

87
Q

Exaptations

A

A trait that evolves to function differently from its original intended use

88
Q

Phrenology

A

An outdated method that used different parts of the brain to measure the person’s character and mental abilities

89
Q

Sexual Selection

A

A trait that may not be useful for survival but useful for mating

90
Q

phyletic gradualism

A

species are unstable and constantly changing through time

91
Q

Who coined the terms descent with modification and what does it mean?

A

Charles Darwin

92
Q

Inheritance of acquired characteristics and is it accepted today?
What is it who made it

A

Lamarck and no
