Patterns of Evolution/Natural Selection

Butterflies, bats, and birds all have wings that allow them to fly. Butterfly wings, however do not have bones like bat and bird wings do. What kind of evolution is this?

• Convergent Evolution

• Divergent Evolution

• Punctuated Equilibrium

• Gradualism

A population of mollusks are living in a stable ecosystem in the ocean. A rapid drop in sea level causes the formation of a lake, which isolateds a group of mollusks from the rest. This quick environmental change causes rapid evolutionary change. What pattern of evolution is this?

• Convergent Evolution

• Divergent Evolution

• Punctuated Equilibrium

• Gradualism

4000 years ago a population of cichlid fish were isolated in Lake Nagubago in central Uganda. Since then 5 new species have formed, distinguished by their differing coloration and mating rituals. These five groups of fish are considered unique species because they do not naturally interbreed.

The Dodo was a flightless bird, first spotted by Dutch sailors in 1598. Dodos had no known predators until sailors started hunting them and new invasive species were introduced. The last sighting of a Dodo was in 1662. What pattern of evolution is this?

• Coevolution

• Convergent Evolution

• Divergent Evolution

• Extinction

Male bumblebees go to flowers, such as orchids, to pick up chemicals that allow them to create attractive scents to put off for female bumblebees. Flowers have waxy pollen to stick to the bumblebee's heads and abdomens in order to spread their pollen to other flowers. What pattern of evolution is this?

• Convergent Evolution

• Coevolution

• Gradualism

• Punctuated Equilibrium

Type of speciation that occurs without geographic isolation.

• Allopatric Speciation

• Sympatric Speciation

• Prezygotic Speciation

• Postzygotic Speciation

Type of speciation caused when populations of a species become geographically isolated and evolve independently

• Allopatric Speciation

• Sympatric Speciation

• Prezygotic Speciaiton

• Postzygotic Speciation

Fossil evidence suggests that whales evolved from land mammals. This was a slow process over thousands of years that resulted from continual reduction of the ancestral mammals forelimbs over time, until they were reduced to fins. What pattern of evolution is this?

• Coevolution

• Convergent Evolution

• Gradualism

• Punctuated Equilibrium
