Patterns of Evolution

Diversification of one ancestral species into many descendent species, usually adapted to a wide range of environments

• gradualism

• punctuated equilibrium

• adaptive radiation

Structures that do the same job, but are built differently are called

• Homologous

• Analogous

• Vestigial

NGSS.MS-LS4-2

Structures that no longer serve a purpose in a living thing, like hip bones in whales, are called

• Homologous

• Analogous

• Vestigial

Sharks, penguins, and dolphins all have flippers used for swimming, even though they are unrelated. These structures are

• homologous

• analogous

• vestigial

All dogs have the common ancestor the wolf. This is an example of -

• divergent evolution

• convergent evolution

• coevoltuion

Tags

NGSS.MS-LS4-2

Evolution toward different characteristics in closely related species (2 related species becoming more different).

• convergent evolution

• divergent evolution

• coevolution

NGSS.MS-LS4-4

Process in which species evolve in response to changes in each other (they evolve and change together).

• convergent evolution

• divergent evolution

• coevolution

Birds, bats, and pterosaurs are unrelated, but they all developed wings to fly. This is an example of

• convergent evolution

• divergent evolution

• coevolution

Why is this a beneficial relationship?

• one animal is helped and one is harmed

• both animals get something good for them

• both animals are harmed

Which of the folllowing is an exammple of a vestigial structure for the ostrich?

• Big legs

• the long neck

• wings
