Question

the concept of evolution by way of natural selection is a central tenet in biology that has been tested in numerous ways by many scientists. evolution by way of natural selection is most likely which type of concept?
○ an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation
○ a likelihood based on the chance that a particular event will or will not occur during an experiment
○ a testable explanation or answer to a scientific question based on prior knowledge or research
○ a statement of fact that is accepted as true because it has always been observed to be true through observations and experimentation

Explanation:

• Option 1: A scientific theory, like evolution by natural selection, is an explanation of phenomena supported by repeated observations and experimentation.
• Option 2: This describes probability, not a scientific theory.
• Option 3: This describes a hypothesis, not a well - established theory.
• Option 4: Scientific theories are not just statements of fact. They are comprehensive explanations that can be modified as new evidence emerges.

Answer:

an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation
