A hierarchy of trust.

For Darwin’s own words and working process, we link to digitized publications, notebooks, manuscripts, and correspondence. For modern claims, we prioritize peer-reviewed synthesis, museum research programs, geological standards, and university collections.

Popular explanations may help orientation, but they do not replace the evidentiary trail behind a contested or precise claim.

What a citation should do.

• Identify the publication, collection, or institution clearly enough to find it again.
• Support the claim beside it—not merely the general subject.
• Prefer stable pages, persistent identifiers, and original editions when available.
• Separate historical testimony from modern scientific interpretation.

Images are reconstructions.

The site’s generated plates are atmospheric scientific illustrations, not photographs of extinct worlds. They contain no embedded labels, and their captions identify subject, period, and interpretive status outside the image.

Anatomical plausibility is part of the brief, but no reconstruction can recover color, behavior, soft tissue, or habitat detail with equal confidence.
