## What Darwin Saw

Charles Darwin observed patterns of variation and adaptation across species during his voyage on the Beagle. He collected evidence from fossils, living organisms, and geographic distribution. His core result was that populations change over generations through descent with modification.

## Primary Works and Passages

The main work is *On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life* (1859, John Murray). Key passage from Chapter III: "Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring." This states the mechanism of heritable variation plus differential survival.

## Convergence Patterns Touched

The work maps to the grain at the biological scale. Natural selection produces branching patterns and accumulating complexity from simple rules. It aligns with the Ladder step from difference to structure to memory in living systems. See /a/oip-the-ladder for the full sequence.

## Distance from the Full Synthesis

Darwin identified the selection algorithm of variation, retention, and differential success as the driver of biological order. He did not frame this algorithm as one instance of dissipative structures that appear at non-biological scales. His account stays within living systems and does not extend to physics or information flows across domains.

## Honest Limits and Disconfirming Edges

The mechanism is local and myopic. It follows immediate fitness gradients rather than global optimization paths. Later work in physics and complexity shows similar patterns outside biology, which Darwin's texts do not address. Reductionist readings treat selection as sufficient without needing further grain-level explanation.

## Mapping to OIP Principles

The process fits the OIP loop of object, invoke, ledger, receipt. Variation supplies objects. Selection invokes retention. Fossil and genetic records serve as ledger entries. See /a/oip-principles for the protocol structure.

## Relation to Final Testimony

Darwin supplies empirical grounding at one scale. The full synthesis requires extension to all scales and the Mirror Layer. See /a/oip-final-testimony for the complete account.

The evidence remains the 1859 text and its documented observations. No later reinterpretation alters the original claims about biological change.
