Stated that the Earth is the fixed center, with the Sun and Moon orbiting the Earth, and the Copernican Revolution (16th Century): other planets revolving around the Sun.

Stated that organisms have the ability to adapt to their environment and gradually change into forms that are more competitive for survival, a process known as evolution.  Examples: boss was there, she decided to wait another minute or two until she sat down to eat. o Sally was thirsty and drank from Mr. Antonio's glass instead of waiting for the server.

Example: o Sarah knew she could steal supplies from work without being caught, but she chose not to take anything because she recognized that stealing was wrong. o Maggie couldn't remember the answer to test question #12, even though she had studied.
