Ecology/Evolution

Which of the following is the collection of life's remains found in sedimentary rock?

• natural selection

• homologous structures

• Charles Darwin

• the fossil record

Similarities in bone arrangements, like those in the picture, support the hypothesis that...

• these organisms are not well adapted

• these organisms share a common ancestor

• these organisms all share the same DNA sequences

• these organisms are members of the same species

This is the process by which organisms with variations more suited to their local environment survive and leave more offspring:

• artificial selection

• selective breeding

• common descent

• natural selection

Biological fitness is defined as __________.

• the ability of an organism to survive and reproduce

• the average life span of an organism

• the amount of energy an organism can use in the environment

• the average life span of an organism

Which of the following is NOT an example of evolution?

• Over many generations, wild teosinte has become corn.

• When the Grand Canyon formed, it geographically divided a squirrel population into two populations, which developed into distinct species.

• A frog begins its life as a tadpole, but becomes an amphibian.

• Finches in the Galapagos islands have diversified over time into many species each well-suited for eating a particular type of food.

Which of the following statements is INCORRECT ?

• Without mutations, there would be no evolution

• Mutations create diversity among life-forms

• Mutations are the source of new phenotypes

• Mutations happen when there is a need for a new trait in a population

Which of the following statements best describes what the word  'fittest'  means in the phrase "Survival of the fittest". 

• The organism that survives in their environment to produce more offspring is the fittest.

• The organism that collects the most resources is the fittest

• The organism that becomes the strongest individual is the fittest

• The organism that lives the longest is the fittest. 

In science, the inheritance of a structure that results from natural selection and by which the organism becomes better able to survive and reproduce is called

• mutation

• advantage

• adaptation

• evolution

How do fossils support evolution?

• The fossil record provides evidence that organisms have changed over time.

• Individual species disappear and reappear in the fossil record over time.

• The fossil record provides evidence that all organisms developed at the same time.

• Organisms in the fossil record are identical to living organisms.

Who created the theory of evolution?

• Charles Darwin
• Charles Derwin
• Charlie Darwin
• Chris Darwin
