Which of the following is NOT an example of natural selection?

• People selectively breeding hamsters for size.

• Insect populations developing resistance to certain pesticides.

• Bacteria becoming resistant to antibiotics.

• Male birds of certain species inheriting colorful feathers that are more attractive to females.

An adaptation is

• The process by which species of organisms change over time

• a trait that helps an organism survive in a particular setting

• When you get bit by a spider and get cool Spider -senses

• Evolution by Natural Selection

• Populations

• Evolution by Gradualism

• Gravitation

Natural selection is described as “survival of the fittest”. Which will surviving fit organisms accomplish?

• migrate to other areas

• reproduce and pass on genes

• have a large territory

• have more genetic mutations

Natural selection is the process by which

• the age of selected fossils is calculated

• organisms with traits well suited to their environment survive and reproduce at a greater rate than less well-adapted organisms in the same environment

• acquired traits are passed on from one generation to the next

• all of the above
