They use the process of elimination through:
Reasoning : Emperical testing(Experiments or observations)

Observations : Explanations
Two Types of Explanations?
Hypotheses : Theories
Another word for tenative explanations?
Hypothesis
Properties shared by all living things (8 of them)
- Common chemical structure
- Common Physiology
- Inherited genetic program
- Ability to self regulate. (Homeostasis)
- Ability to sense and respond to stimuli in the environment
- Capacity to grow and reproduce
- Ability to bind and release energy
- Capacity to evolve
The word for an explanation that is broader in scope than a hypothesis, generates new hypotheses, and is supported by a large body of evidence
Theory
View of life in which: Living things are no different from non-living things & Can be described by the law of physics and chemistry
Mechanistic
