Purpose
In this assignment, you will analyze an example of specialization by researching the finches of the
Galapagos Islands. Then you will answer questions to construct explanations and draw conclusions
based on the information you gather.
Background Information
Biogeographical isolation may occur when populations are geographically separated, anatomically
incompatible, behaviorally different, or temporarily isolated. Any of these mechanisms, or a combination
of them, may lead to speciation if they result in reproductive isolation.
A classic example of speciation as a result of geographic isolation is the finches of the Galapagos
Islands. Charles Darwin hypothesized, theorized, and drew conclusions about evolution based on his
observations of these finches.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
