Answer to Question 1

Earth has evolved internally and externally. As internal processes were established, they played a role
in what was happening on the surface of Earth as the atmosphere, hydrosphere, and landmasses
developed. Organic evolution was directly dependent on development of favorable conditions for
different life forms. The net result of the physical, chemical, and biological evolution of Earth has been
profound, particularly, in light of the amount of time necessary for those changes to take place
(synthesis).

Answer to Question 2

All living things are related and have descended with modification from organisms that lived in the
past. The mechanism is called natural selection, which states that the organisms that are best adapted
to their environment are the most likely to survive to reproduce, causing species to evolve with time.
