a) examples of fossils. b) acquired traits. c) vestigial structures. d) examples of natural variation.
When a farmer breeds only his or her best livestock, the process involved is
a) natural selection. b) artificial selection. c) artificial variation. d) survival of the fittest.
Which statement about the members of a population that live long enough to reproduce is consistent with the theory of natural selection?
a) They transmit characteristics acquired by use and disuse to their offspring. b) They tend to produce fewer offspring than others in the population. c) They are the ones that are best adapted to survive in their environment. d) They will perpetuate unfavorable changes in the species.

Jean-Baptiste Lamarck proposed that organisms
a) have an innate tendency toward complexity and perfection. b) have an innate tendency to become simpler as time passes. c) inherit all of the adaptations they display. d) belong to species that never change.
The species of finches that Charles Darwin found on the Galápagos Islands displayed different structural adaptations. One of the adaptations that Darwin noted was the

Which process has the greatest effect in determining which members of a population are most likely to survive until reproductive age?
a) Evolution b) Natural selection c) Meiosis d) Hybridization
According to Darwin’s theory of evolution, what causes the struggle for survival in populations?
a) Overproduction of offspring b) Favourable heritable variations c) Natural selection d) Competition between the fittest individuals in the population
Why has evolution resulted in antibiotic resistance in bacteria?
a) Not completing a course of antibiotics allows resistant bacteria to develop. b) Bacteria resistant to the antibiotic survive to pass on this characteristic to their offspring c) Bacteria change their metabolism to cope with the presence of antibiotics. d) Bacteria have learnt how to neutralize the effects of the antibiotic and they pass this onto their offspring.
What is natural selection?
a) Making a random choice of partner for reproduction b) Increased reproductive success by those with favourable variation c) Variation due to mutations in a population d) The survival of the largest organisms in a population
What is natural selection?
a) The mechanism that increases the chance of certain individuals reproducing. b) The mechanism that leads to increasing variation within a population. c) The cumulative change in the heritable characteristics of a population. d) The mechanism that explains why populations produce more offspring than the environment can support.
