Unit 6 Evolution Practice

Evolution of a single species over a short time scale

• microevolution

• macroevolution

• coevolution

• adaptive evolution

Evolution over a large time scale that includes creation and destruction of species

• microevolution

• macroevolution

• coevolution

• natural selection

The process of individuals that have physical or behavioral traits that better suit their environment and cause them to survive better and reproduce more is called...

• divergent evolution

• descent with modification

• natural selection

• mimicry

Natural selection acts on ____, not ____.

• individuals, populations

• populations, individuals

What does it mean for an individual to be "fit"?

• high likelihood of becoming fossilized

• has multiple habitats

• makes more healthy offspring

• has more mates

What explains why individuals develop certain traits? (i.e. long neck in giraffes, colorful feathers in peacocks, webbed feet in ducks)

• they are beneficial to them and make them more fit

• they help them acquire more food

• they make them easier to fossilize

• they are easier to pass down to offspring

A model of evolution where gradual change occurs over a long period of time

• gradualism

• punctuated equilibrium

• macroevolution

• microevolution

Model of evolution where there are periods of rapid change followed by periods of little or no change

• gradualism

• punctuated equilibrium

• microevolution

• macroevolution

Which of the following must be true for a population in order for Hardy-Weiberg Equilibrium to be applied? (select all that apply)

• large population size

• random mating

• no immigration or emigration

• no mutations

• no natural selection

What is the term for the development of differences between groups of the same species, which can then become so different that they can no longer interbreed, developing a new species?

• convergent evolution

• adaptation

• coevolution

• divergent evolution
