❓ Quick answer
Is evolution a fact or a theory?
Evolution is both a fact (species have changed over time, supported by overwhelming evidence) and a theory (natural selection is the scientific explanation for how and why this occurs). In science, theories are the highest level of explanation supported by evidence.
❓ Quick answer
Can evolution be disproven?
Yes, if we found no fossil evidence of transitions, if species could not be shown to share common ancestors, or if we observed traits increasing in frequency despite reducing survival. None of these have occurred. Instead, new evidence from DNA consistently supports evolution.
❓ Quick answer
