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:

1. Analyze each option:

• Option 1: A scientific theory (like evolution by natural selection) is an explanation of phenomena supported by repeated observations and experimentation. Evolution has been tested by many scientists, so this fits.
• Option 2: This describes probability, not a scientific concept like evolution. Eliminate.
• Option 3: This is a hypothesis, not a well - supported concept like evolution (which is a theory). Eliminate.
• Option 4: A law is a statement of fact always observed, but evolution is a theory (explanation), not a law. Eliminate.

Answer:

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