what did Charles Darwin observe in finch populations of the Galapagos Islands off the coast of South America?

• different species on different islands
• all species on one of the islands
• identical species on all the islands
• the same species as North America

What is suggested by the anatomical similarity of different species of vertebrates?

• no evolutionary relationships between the groups

• recent common ancestry

• similar environments in the past

• evolution from a distant common ancestor

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

If an organism has a vestigial structure, that structure likely once had a function in a(n)

• close relative
• early ancestor
• unrelated organism
• embryological stage

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

What is speciation?

• combining of tow species to form one with different traits
• isolation that affects mating behaviors
• timing of mating that prevents normal sexual selection
• divergence of two or more species from an existing one

An earthquake causes an ocean channel top open and separate an island into two.  the species on each section are now in

• geographic isoliation
• behavioral isolation
• disruptive selection
• temporal isolation

The study of the early stages of development that is one evidence of evolution is:

• Homologous Structures
• Embryology
• Vestigial Organs

The table shows the survival rate of two types of beetles in the same environment over a period of three years.  

Which statement about the beetles in this environment is best supported by the data?

• Brown beetles have a shorter life cycle than green beetles have
• Green beetles are more fit for their environment than brown beetles
•  brown beetles are undergo more unfavorable mutations than green beetles
