Evolution - Classification Retake

Scientist such as Charles Darwin view the fossil record as

• interesting but unrelated to the evolution of a species

• evidence that earth was a 1000 years old

• a record and evidence of evolution

• evidence that traits are aquired through use or disuse

Structures that share a common ancestory or are similiar in structure are

• young in origin

• homologous

• analogous

• vestigial

An adaptation is an inherited characteristic that can be

• physical or geographical

• physical or behavioral and helps the organism survive

• aquired suring its lifetime

• the result of artificial selection

Variation within a species is imortant to Darwin's theory of evolution. Which statement ecplains how variation is important?

• Some organisms survive and reproduce better than others

• competition is fierce among members of different species.

• Populations often increase rapidly without warning

• Resourcesbecome limited over long periods of time.

Biologists use classification system to group organismsin part because organisms

• share too many derived traits

• are going extinct

• are very numerous and diverse

• are too much alike

Scientist use a universally accepted naming system called

• traditional classification

• binomial nomenclature

• cladastics

• the three domains

Many types of butterflies have large circles on their wings. Animals that like to eat the butterflies often mistake circles for eyesand are scared away. This is an example of

• Adaptation

• Extinction

• Behavior

• Phylogeny

The second part of the scientific name is unique to each

• family in its order

• order in its class

• species in a genus

• genus in a family

In binomial nomenclature which of the to terms is capitalized?

• neither the first or second

• both
