Front 1

Evolution

Back 1

change in gene frequency through time

Front 2

Linnaeus

Back 2

systematics: dichotomous system, defined species and therefore showed evolutionary relationships

Front 3

Gradualism

Back 3

evolution proceeds at a slow pace

Front 4

Uniformitarianism

Back 4

All pressures act on the whole world at all times

Front 5

Punctuated Equilibrium

Back 5

Periods of stasis/change

Front 6

Lamarck

Back 6

Acquire a beneficial character (he understood benefits, but not genetics)

Front 7

Lysenko

Back 7

Impose hereditary characteristics without genetics, ie bonsai tree
(WRONG!)

Front 8

Artificial selection/breeding

Back 8

Lots of different plants can stem from the same one; dogs (foraging, feeding behavior), brocciloflour;

Front 9

Natural selection, adaptation

Back 9

Confer advantage to outreproducing others

Front 10

Mayr's five points (modern synthesis)

Back 10

1-Population growth potential (need a cap)
2-Population growth stability (equilibrium between growth/resource)
3-Limited resources (can't sustain)
4-Phenotypic Variation
5-Genetic Variation (genetic advantage is a man whose genes are overrepresented in descendant generations (666 kids)

Front 11

Homology

Back 11

Shared feature from same origin (same bone in human/cat)

Front 12

Analogy

Back 12

Shared feature from different origin (bat/fly/bird wing)

Front 13

Convergent evolution

Back 13

Same solutions through different means (analogies)

Front 14

Vestigial Organs

Back 14

No purpose now, but had one before: human tailbones, snake's/marine mammals bone structure for legs)

Front 15

Principle of antithesis

Back 15

-Opposite positions display opposite meanings (angry/scared dog)
-Bird droppings?

Front 16

Aposematic coloration
Vs.
Crypsis

Back 16

Stand out, warning symbol if bad/poisenous
Vs.
Camouflage if vulnerable

Housefly

Front 21

Inter sexual selection

Back 21

between sex (women being choosy)

Front 22

Intra-sexual selection

Back 22

Within sex, male to male competition

Front 23

Which of the following is not an observation or inference on which natural selection is based?

Back 23

Poorly adapted individuals never produce offspring.

Front 24

Analysis of forelimb anatomy of humans, bats, and whales shows that humans and bats have fairly similar skeletal structures, while whales have diverged considerably in the shapes and proportions of their bones. However, analysis of several genes in these species suggests that all three diverged from a common ancestor at about the same time. Which of the following is the best explanation for these data?

Back 24

Natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy.

Front 25

Darwin synthesized information from several sources in developing his theory of evolution by natural selection. Which of the following did not influence his thinking?

Back 25

observations of molecular homologies
