Evolution Review

The man who proposed the theory of natural selection and evolution.

• Thomas Moore
• Gregor Mendel
• Neil Degrasse Tyson
• Charles Darwin

A change in a trait or characteristic that increases an organism’s ability to survive and reproduce.

• extinction
• natural selection
• adaptation
• choice

The theory that organisms best adapted to their environment are more likely to survive and reproduce.
"Survival of the fittest."

• Natural selection
• Adaptation
• Extinction
• Fossil

What is the BEST definition for Evolution?

• Change
• Adaptation
• Nature's power
• Change over time

How would a warming climate affect the species in an ecosystem?

• individuals might die off but a species cannot disappear completely

• species would increase in number to offset the numbers killed by the heat

• species that have never been seen before would suddenly appear

• individuals best able to survive the heat would become more numerous

Which of the following are examples of geographic isolation?

• When a storm blows a population of finches to a new island so they can no longer mate with the finches on the mainland

• A mountain range prevents two types of goat from mating, causing the gene pool to become less varied

• Two populations of deer living near each other happen to mate during different times of the year

• A deepening canyon cuts two populations of squirrels off from each other

• Two populations of birds have developed different mating calls

Which of the following would most likely prevent two populations of field mice from breeding?

• Active time of day

• Color

• Average weight

• Favorite food

What is speciation?

• when a population reaches a balance and change is no longer occuring

• when populations move away from each other

• when species begin to pass on acquired traits and change their behavior

• when two species can no longer interbreed

What does the similarity of these structures tell us about these organisms?

• They grow at different rates

• they have a common ancestor

• They evolved slowly

• They do the same thing

What do we call similar structures that were passed down from a common ancestor?

• vestigal structures

• variable structures

• homologous structures

• fossil structures
