Patterns Of Evolution

Question 1

Mass extinctions

Answer 1

Events during which many species become extinct over a relatively short period of time which allows surviving organisms to evolve

Question 2

Adaptive radiation

Answer 2

A single species or a small group of species has evolved through natural selection and other processes into several different form that live in different ways

Question 3

Convergent evolution

Answer 3

Unrelated organisms come to resemble one another

Question 4

Analogous structure

Answer 4

Same in function but not in structure shoes no sign of evolution

Question 5

Divergent evolution

Answer 5

Species that resembled the ancestral species but has become more and more distant
Occurs when species begin to adapt to different environmental conditions
Supported by homologous structures

Question 6

Coevolution

Answer 6

Two species evolve in response to change in each other over time

Question 7

Punctuated equillibrium

Answer 7

Patterns long, stable periods interrupted by brief periods of more rapid change

Question 8

Gradualism

Answer 8

Darwin wanted it to be slow and steady

Question 9

Macroevolutionary patterns

Answer 9

Large scale evolutionary patterns and processes that occur over long periods of time
