Guide: https://yenra.com/critical-analysis-of-evolution/
Updated: October 13, 2026

Purpose: examine one scientific or historical assertion without confusing
the evidence with a broader interpretation. Save a copy for each claim.
Use complete source references so another reader can retrace your work.

1. Exact claim in one sentence:


2. Claim type: biological / historical / theological / policy / other
What would count as evidence for this kind of claim?


3. Underlying source: author, title, date, URL, page/section:


4. Observation or data: what was actually recorded, and by which method?


5. Comparison: which alternatives or predictions were examined?


6. Interpretation: what does the author conclude?
Does that conclusion have the same scope as the observation?


7. Limits: sample, period, conditions, missing information:


8. Next question and source to consult:


9. Present assessment: supported within stated limits / unresolved /
contradicted by specified evidence. Explain why; retain uncertainty.


Example (hypothetical): a bacterial population changes after exposure.
This can support an inference about a process under those conditions.
A claim about all species' histories requires additional evidence.
