The Descent of Man (1871) argues human common descent as a dated public treatise, twin of the ranking-passages cost row
In 1871 The Descent of Man argued human common descent as a public treatise. Charles Darwin's documented role is: He wrote the 1871 book. In the causal graph this event strengthens Digital Learning Access, a driver that weakens Learning Poverty Rate (low- and middle-income countries) — an improving welfare path.
Read the full account
In 1871 The Descent of Man argued human common descent as a public treatise. Charles Darwin's documented role is: He wrote the 1871 book. Huxley and others already argued human evolution in public. Ranking passages remain the inequality cost twin, not mixed as a rebate here.
Context
The ranking row stores inequality cost of the same book. This stores the common-descent teaching. Sharing Huxley as a prior public advocate is required. Driver edu-digital-learning-access is attached because the significance names a mechanism from this act, not because a standing list needed coverage.
If a number is not in the two records named above, it is not supplied here.
Why it matters
A public treatise placing humans inside common descent is an education path of high weight. One book, two signs on two rows. The welfare reading on this path is improving.
Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

That reading is an impact-path choice, not a property stored on the Fact itself.
Confidence is stated on the impact path, not hidden in adjectives. Sign lives on the path.
Naming Charles Darwin does not delete co-authors, institutions, or later transmitters. The lag from 1871-02-24 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
