What the evidence says

six tiers, never blended

emerging — human data exists, and it is thin or contested

every claim resolves to its source

Evidence, kept apart

The Atlas never mixes evidence types into one blob. Each claim below carries the tier it actually sits in; an unresolved citation is shown and does not move the page.
