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 observation 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 theory.
• Option 3: This is a hypothesis, not a well - established theory.
• Option 4: A scientific theory is not just a statement of fact (facts are components, but a theory explains a wide range of facts).

Answer:

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