C) Postulated ___ development and ____ across species (i.e. that ___ organisms ___ from ____ ___)

A

A) Animal kingdom could be ordered from simple to complex on a ladder of nature (scala naturae), with humans on top.

4) \_\_\_ of A\_\_ T\_\_\_
A

1) First systematic theory of animal evolution, now called the Doctrine of Inheritance of Acquired Characteristics.
2) Said current species developed from older species, more complex animals from simpler, by inheriting characteristics ancestors acquired by experience. Proposed ideas of:

6
A
  1. collection of background information (he thought anthropologists the gold standard bc they looked at cultures). accumulate basic info from all available sources
  2. classification of behavior (create behavioral taxonomy based on broad characteristics of behavior. instincts)
  3. developing research preparations (find species and test situations that demonstrate stage 2 classes. (find species that’s an example of behavior you want to study)
  4. identification of variables associated with behavioral class
  5. making comparisons (compare behaviors w/in and between stages 1-4)
  6. identification of general mechanisms (when this produces understanding of relationships among classes, a general theory results)

49
Q

historical mechanisms of inheritance

A
  1. spontaneous generation
  2. ovism
  3. spermism
50
Q

spontaneous generation mechanism of inheritance

A
  • Life arose from combinations of things in the environment.
  • An early attempt to explain the origin of life
  • The concept that living things come from nonliving things
  • People believed that toads came from mud, flies came from the rotting bodies of animals, and mice came from cheese.
  • Recipes.
51
Q

ovism

A

each egg contains a complete homunculus. Sperm triggers growth. Homunculus would need eggs with homunculus inside for all later generations.

52
Q

spermism

A

homunculus in sperm. Church worried about unbaptized homunculus in sperm at ejaculation, unfertilized eggs.

53
Q

what’s a homunculus?

A

a representation of a small human being

54
Q

Historical mechanisms of inheritance

  1. M__ I___
  2. L___
  3. P___
  4. M___ G___
A

1) maternal impressions - pregnant woman’s experience influences fetus. (see blind person - blindness. pee in churchyard = bed wetter)
2) lamark: Offspring inherited parental changes due to their experience (epigenetics is proving this)
3) pangenesis: gemmules arise from tissue, gather in reproductive organs
4) mendalian genetics: Genes pass characteristics across generations

55
Q

natural selection

..and Thomas Huzley’s response

A

the differential reproductive success of individuals within a population that occurs because of hereditary differences among them

“how extremely stupid not to have thought of that!”

56
Q

intrasexual

A

Males compete for opportunity. Is when members of the same sex (within a species) compete with each other in order to gain opportunities to mate with others, e.g. the male against male competition for females. Because ____ selection often involves fighting, species or individuals well adapt for this kind of selection will have developed better armourments (weapons) than their competition.

57
Q

Epigamic

A

females choose partners. males look pretty to attract them

58
Q 
{Darwinian or Evolutionary Theory}
Define:
1) Variation

62
Q 
{Darwinian or Evolutionary Theory} we observe
Define:
1) Genetic Variation
2) Heredity
3) Differential Reproduction
A

1) alleles produce different forms of the same protein
2) alleles can be transmitted to offspring

63
Q 
{Darwinian or Evolutionary Theory} we deduce
Define:
1) Variation
2) Heredity
3) Differential Reproduction

64
Q

Darwinian

facts about populations

A

Fact 1 Populations have the potential to increase exponentially.
Fact 2 many populations are at equilibrium size
Fact 3 resources are limited

= Inference 1: Struggle for existence among individuals
Fact 4 Individuals are unique
Fact 5 individual variation is often heritable

= Inference 2 Differential survival/reproduction/natural selection

= Inference 3 Through many generations, evolution

(issues with hypothesis)
2)
3)
A

1) self defense (but they Mob mostly during breeding, so not self defense)
2) Advertising oneself as a mate (mobbers usually have young in nest, so not advertisement)
3) Parental care of nest (mobbers usually have young in nest, so parental care seems correct)

85
