Evolution Unit Test Review

Although individuals in one species are similar enough to reproduce together, each have a unique combination of traits that allow some an easier time finding shelter, acquiring food, attracting mates, etc. These differences between individuals is a requirement of natural selection called:

• overproduction

• inherited variation

• successful reproduction

• struggle to survive

It is very common in reptiles to have many, many eggs at a time, as many of those will not survive to adulthood. The fact that more individuals are born than will survive to adulthood is called

• successful reproductin

• descent with modification

• struggle to survive

• overproduction of offspring

Which of the following sequences shows the correct hierarchy of classification, going from broadest to most specific?

• Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain

• Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

• Family, Order, Genus, Species, Domain, Kingdom, Phylum, Class

• Domain, Species, Kingdom, Genus, Phylum, Family, Order, Class

A population of bacteria is treated with hand sanitizer. Because of genetic variation in the population, what is a possible outcome?

• some may be resistant and survive

• they will get better at obtaining a food source

• all of the bacteria are already resistant

• the population will grow quickly

Traits of snakes such as a forked tongue are called ____________________________ due to their shared common ancestor

• homologous structure

• analogous structure

• vestigial structure

Embryology shows share similar bud development. This shows.....

• Development is unique to each species

• female parent determines physical characteristics

• organisms have a common ancestor

Genes that help an organism be more successful reproductively can be expected to

• become more common in the future

• cause the extinction of the species

• cause it to evolve into a new species

An adapatation is

• how an organism evolves during its own lifetime

• a gene an organism has

• any trait an organism possesses

• a trait that helps an organism survive and/or reproduce in its environment

Which of the following is NOT a principle of natural selection?

• Organisms compete for limited resources

• Evolution will occur as an organism gets older and learns more

• In every population adaptations allow some organisms to survive and reproduce better than others.

Which is NOT an example of evolution?

• Horses becoming taller and faster over millions of years.

• Human brains becoming larger over time.

• A caterpillar going through metamorphosis to become a butterfly.
