Evolution Review 2

The pictures show examples of asexual and sexual reproduction strategies.

Based on your knowledge, which reproduction strategy in the models above is more likely to allow for evolution to occur in a species?

• Model A because it is Asexual Reproduction and provides less variation within a species

• Model A because it is Sexual Reproduction and provides more variation within a species

• Model B because is is Asexual Reproduction and provides less variation within a species

• Model B because it is Sexual Reproduction and provides more variation within a species

Bacteria are organisms that reproduce asexually. What does this mean about the bacteria's offspring?

• Offspring are a mix of genes from both parents

• Offspring are identical to the parent

• Offspring are different from the parent

• Offspring get all their genes from dad, and none from mom

What is the process of the formation of new forms from an ancestral species in response to differing habitats?

• Lamarckism

• Adaptive radiation

• convergent evolution

• microevolution

In a population where the allele frequency shifts by random events, like forest fires, the mechanism of evolution at work is which of the following?

• migration

• natural selection

• mutations

• genetic drift

The data table below shows the number of individuals in two different lizard populations exhibiting (with) different traits before and after a ten-year drought.

Which argument is best supported by the data in the table?

• Shorter-bodied lizards and longer-bodied lizards reacted identically to the drought conditions

• Shorter-bodied lizards seem to have been naturally selected against by the drought conditions

• Longer-bodied lizards seem to have been naturally selected for by the drought conditions

• Longer-bodied lizards seem to have been naturally selected against by the drought conditions

A population of mosquitoes is sprayed with a new insecticide. Most of the mosquitoes are killed, but a few survive. In the next generation, the spraying continues, but more mosquitoes hatch that are immune to the insecticide, as seen in the figure below.

• The mosquitoes learned how to fight the insecticide

• The insecticide caused the mosquitoes to develop an immune response, which was inherited

• The insecticide caused the mosquitoes to want to be resistant

• A few mosquitoes in the first population were resistant and passed this resistance to their offspring

Zebras adapted stripes to make them harder to predators to see, and to avoid flies in the Savanna. Lions evolved better color vision due to the black and white striped pattern of zebras on the Savanna. This allowed them to better see the zebras against the brown Savanna grasses.

Which term describes the type of evolution described above?

• Divergent evolution

• Convergent evolution

• Coevolution

• Adaptive radiation

Evidence shows that a shark and dolphin are not closely related, but they both have fins that are adapted for swimming in water. What pattern of evolution is shown between the shark and dolphin?

• Convergent evolution

• Punctuated equilibrium

• Coevolution

• Adaptive Radiation
