
Evolution is the core theme in biology
Descent from a common ancestor with
modification
Natural Selection as the main mechanism that
drives the evolution of adaptive evolutionary
novelties

Life does not occur without energy exchanges
• For example:
Photosynthesis and respiration


All species tend to maintain themselves from
generation to generation using the same
genetic code.
However, there are genetic mechanisms in
place that can lead to change over time, or
evolution.

The way that anything
works is correlated to
its structure.

Scientific Method
Hypothesis characteristics:
• educated guess based on background information
• testable
• Controlled experiment characteristics:
• control group and constants
• experimental group(s)
• independent and dependent variables
hypothesis
experiment
support hypothesis
test repeatedly
reject hypothesis
verify
hypothesis becomes theory
reject hypothesis
modify or abandon hypothesis
