which of the following is not involved in natural selection?

differences in reproductive success

inheritable variation in populations

divergence of two or more species from an existing one

combining of tow species to form one with different traits

isolation that affects mating behaviors

timing of mating that prevents normal sexual selection

What is suggested by the similarity of early embryos of different species of vertebrates?

evolution from a distant common ancestor

no evolutionary relationships between the groups

similar environments in the past

Mutations are important because they bring about

genetic variation needed for a population to evolve

death of the organism in which they develop

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population

Which of the following statements is correct based on the information shown in this cladogram?

the turtle and the frog are more similar to each other than the turtle and the bass

frogs have existed for a longer time that bass

the frog is more closely related to the bass than to the leopard

Which of the following evolutionary forces can introduce new genetic variation into a population?

natural selection and non-random mating

natural selection and genetic drift

A mutation occurs in a particular animal and quickly begins to increase in frequency throughout the population. Which of the following are you most likely to conclude?

The mutation increase the probability that the animal will reproduce.

The mutation makes the animal grow larger

The mutation does not confer any benefit or harm to the animal

The mutation makes the animal more susceptible to predators

be the most recent ancestor of primates

have a short generation time and are easy to study

possess shared derived characteristics of the included species

Which statement correctly explains how resistance to penicillin appeared after a few years of its widespread use to fight bacterial infection?

some bacteria were resistant to penicillin and their population spread rapidly, without competition from bacteria that were killed by penicillin

in order to survive exposure to penicillin, bacteria developed a resistance to the drug

a few bacteria became resistant to penicillin, and through sexual reproduction , most bacteria acquired the resistance

penicillin never really successfully wiped out populations of bacteria, scientist did not use proper controls in their studies

The Hardy-Weinberg Model is?

A mathematical tool that biologists can use to predict allele frequencies and determine whether or not evolution is occurring within a population.

Available at local hobby stores and retailers throughout the Greater Cleveland area.

Always occurring within populations of organisms in nature.

Only useful in the lab and cannot be practically applied to real-world populations of organisms.

Two populations of a species of squirrel are isolated from each other. One population is larger in number than the other. A new disease, which is easily spread and extremely contagious, affects both populations at the same time. Which of the following is the best prediction of how the new disease will affect the two populations?

The smaller population will be more affected as they have less genetic variation

The two populations will be equally affected as they are the same species

The larger population will be more affected as they have greater genetic variation

The smaller population will not be affected

Genetic drift is change in the allele frequency of a population due to...

non-random mating (sexual selection)

Which of the following is an example of the bottle neck effect ?

Bald Eagles are hunted until near extinction, population recovers.

Small group of iguanas floats to an island, starts a new population.

Red fox pups are more likely to survive in a snowy environment if they are born white.

Farmer chooses seeds from largest apples to plant next year. This results in larger apples from year to year.

Which of the following is an example of artificial selection ?

Farmer chooses seeds from largest apples to plant next year. This results in larger apples from year to year.

Bald Eagles are hunted until near extinction, population recovers.

Small group of iguanas floats to an island, starts a new population.

Red fox pups are more likely to survive in a snowy environment if they are born white.

Which statement is part of Darwin’s theory of evolution by natural selection?

More offspring are produced than can possibly survive.

The organisms that are the fittest are always largest and strongest.

The number of offspring is not related to fitness.

Acquired characteristics that are inherited are the cause of evolution.
