chapter 10 review

In natural selection, selection is caused by

• humans

• mutations

• breeders

• environment

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

What is the term for a feature that allows an organism to survive better in its environment?

• variation

• adaptation

• homologous structure

• vestigial structure

Natural selection results in change over time by acting on traits that are

• heritable
• new
• mutated 
• better than the best

Darwin wrote that organisms with traits that are best suited to the environment will ________________

• increase in number
  
• become extinct
  

Choose which scientist corresponds best with the statement:

The gradual change in species over time is...

• Evolution
• Nucleotide 
• Adaptation
• Natural Selection

What is another name for natural selection?

• survival of the smartest
• survival of the fastest
• survival of the biggest
• survival of the fittest

What is the study of organisms at the early stages of development?

• DNA studies
• embryology 
• extinction
• fossil record

When organisms are better adapted to their environment they will survive and reproduce more successfully than organisms less adapted. This process is called what?

• Selective breeding

• Natural Selection

• Cloning

• Evolution of all species
