A species is a group of similar organisms that

• Can mate with each other and produce fertile offspring
• can live together on an island
• can migrate to an island from the mainland
• all have exactly the same traits.

What did Darwin observe about finches in the Galapagos Islands?

• Their feathers were adapted to match their environment
• Their beaks were adaptations related to the foods the finches ate
• they all had identical phenotypes in all locations
• they had identical genotypes in all locations

The endangered seabird the marbled murrelet, in California, is dependent upon Sequoia forests and trees for survival.  What might happen to the marbled murrelet population if the sequoia population went extinct?

• the population of marbled murrelet would remain the same
• the population of marbled murrelet would increase
• The marbled murrelet would go extinct
• the marbled murThe marbled murrelet would be placed on the threatened species list

how does natural selection lead to evolution?

• stronger offspring kill weaker members of the species.
• helpful variations accumulate among surviving members of the species.
• Overproduction provides food for stronger members of the species.
• environmental changes favor weaker members of the species
