Question

charles darwin had many ideas and made many observations about how life evolves on earth. did this lead to a law or a theory?
a law
a theory

Explanation:

In science, a theory is a well - substantiated explanation of some aspect of the natural world, based on a body of facts. Darwin's work on evolution (natural selection) is a theory because it explains how life evolves, supported by observations and evidence. A law describes a phenomenon, while a theory explains it. Darwin's ideas about evolution explain the process of evolution, so it's a theory.

Answer:

a theory
