The 1831–36 Beagle voyage is Darwin's dated field education in geology and natural history, not a later festival
From 27 December 1831 to 1836 Darwin sailed on the Beagle as a dated field education in geology and natural history. The instrument is that voyage, not a 2009 festival and not the 1859 Origin as a duplicate. 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
From 27 December 1831 to 1836 Darwin sailed on the Beagle as a dated field education in geology and natural history. The instrument is that voyage, not a 2009 festival and not the 1859 Origin as a duplicate. Charles Darwin's documented role is: He kept notes and collected. FitzRoy sailed the ship. Henslow placed him. Admiralty patronage remains the cost twin, not mixed as a rebate here.
Context
FitzRoy and Henslow share the placement. Sharing unnamed sailors is required. Collecting-as-extraction remains a cost row. The setting of The 1831–36 Beagle voyage is Darwin's dated field education in geology and natural history, not a later festival is the public file around 1831-12-27. Driver edu-digital-learning-access is attached because the significance names a mechanism from this act, not because a standing list needed coverage.
Why it matters
Improving path from The 1831–36 Beagle voyage is Darwin's dated field education in geology and natural history, not a later festival on 1831-12-27. A five-year field education is an education path of high weight. A 2009 festival is not this voyage. The welfare reading on this path is improving.

Confidence is stated on the impact path, not hidden in adjectives. One voyage. Mixed effects of The 1831–36 Beagle voyage is Darwin's dated field education in geology and natural history, not a later festival are separate paths.
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.
Shared responsibility is part of The 1831–36 Beagle voyage is Darwin's dated field education in geology and natural history, not a later festival. Naming Charles Darwin does not delete co-authors, institutions, or later transmitters. The lag from 1831-12-27 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.
