Evolution

Ostrich wings are examples of

• homologous structures
• vestigial structures
• adaptations
• traits

Natural selection is

• survival of the fittest
• humans change
• two species are the same
• more animals survive

Which of the following is not a piece of evidence for evolution?

• Homologous structures
• embryology
• fossil age
• vestigial structures

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
