Evolution via Natural Selection

What is the advantage of having different shaped beaks?

• To look different from other species.
• To be able to eat the food readily available in the environment.
• To protect itself against predators.
• To protect itself against prey.

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Why would a population with a large amount of genetic variation be more likely to survive a severe climate change in its environment?

• Individuals will only create offspring well-suited to the climate change
• The individuals would produce more offspring
• Individuals better suited to the new climate will help less-suited individuals survive
• Some individuals will posses traits better suited to the new climate and be more likely to pass them on

Which of the following is a fossil?

• mutations
• breeders
• environment

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures
