variation

adaptation

homologous chromosome

vestigial structure

For questions #16-19 use the scenario below to help answer. A biologist spent many years researching the rate of evolutionary change in the finch populations of a group of islands. It was determined that the average beak size (both length and mass) of finches in a certain population increased dramatically during an intense drought between 1981 and 1987. During the drought, there was a reduction in the number of plants producing thin-walled seeds.

1

Which of the following procedures was most likely followed to determine the change in beak size?

A few finches were trapped in 1981 and again in 1987, and their beak sizes were compared.

The beak size in fifteen finches was measured in 1987, and the beak size in the original finches was determined by estimation.

The beak size in a large number of finches was measured every year from 1981 to 1987.

Finches were captured and bred in 1981, and the beak size of the offspring was measured.

1

Which of the following statements might best explain the increase in average beak size in the finch population during the drought?

Finches with bigger beaks are better able to crack thick-walled seeds and produce more surviving offspring

Finches with bigger beaks can attack and kill finches with smaller beaks.

Finches with bigger beaks possess more powerful flight muscles and are able to find more food.

Finches that crack large seeds develop larger beaks over time.

1

Which of the following best describes the mechanism behind the change in beak size in the finch population?

The formation of two new finch species from a single parent species

A change in gene frequencies in the finch population due to selective pressure from the environmental change

A new allele appearing in the finch population as a result of mutation

The achievement of dynamic equilibrium in the finch population as a result of homeostasis

1

The biologist discovered that from 1988 to 1993, the average beak size declined to pre-1981 levels. The reversal in beak size from 1988 to 1993 was most likely related to which of the following events?

A loss of food supply for the finches

The end of the drought

An increase in drought conditions

An increase in predators consuming finches

1

DNA sequences can be used to determine the evolutionary relationships of species because

organisms with similar anatomy will develop similar DNA sequences by convergent mutations

DNA sequences for proteins never change, so two species that have the same protein will have the same DNA sequence

natural selection causes organisms that live in similar environmental conditions to have the same mutations in their DNA sequences

mutations occur randomly in DNA at a steady rate, so the number of DNA difference is equivalent to the time since a pair of species that shared a common ancestor

The remnant of an organ that had a function in an early ancestor is known as a(n)

analogous structure

homologous structure

vestigial structure

fossil structure

Define: Homologous structures (kate)

structures that are reduced forms of functional structures in other organisms

set of one maternal and one paternal chromosome that pair up during meiosis

similar in construction but are not inherited from a common ancestor

anatomically similar structures inherited from a common ancestor

1

Principle of Selection… (scotty)

a)States that some forms are more successful at surviving and reproducing than other

forms in a given in environment

b) States that specific members of a population will survive for longer than others

c) States that parents select certain members of their offspring to parent

d) States that the food chain of an ecosystem selects how long an organism survives for

1

What is natural selection? (phone)

a) Cumulative changes in groups of organisms through time

b) Mechanism that leads to evolution due to variation in heritable traits and differential reproduction in a population

c) It’s the principle of heredi

d) It’s a selection of animals made by the nature

1

Define behavioral adaptations (enzo p)

a. Response made by an organism to help survive and reproduce

b. A body process that helps an organism survive and reproduce

c. A feature of an organism's body that helps it reproduce

d. When a animals fitness is way to low and has trouble surviving

1

How does adaptation work? (sebastian)

a. It is a trait shaped by natural selection that increases an organism's reproductive success

b. better adaptation to an environment leads to better evolutionary fitness

c. a cumulative change in groups of organisms through time

d. both A and B

1

c. camouflage is an example of physiological adaptation

d. mimicry is an example of structural adaptation
