Domain-specific¶
- Baldwin Effect
- Hinton and Nowlan (1987), in silico. A genome has 20 positions, each gene fixed (1 or 0) or plastic (?); fitness is nonzero only for one specific 20-bit target
This sourceThe source simulation: 'the genotype has 20 genes, each of which has three alternative forms (alleles) called 1, 0, and ?', and the network 'only confers added reproductive fitness on the organism if it is connected in exactly the right way'. The simulation result: a lifetime of up to 1,000 random trials turns an isolated fitness spike into a gradient selection can climb, and undecided alleles are progressively replaced — though Hinton and Nowlan report the replacement as incomplete, since 'there is very little selective pressure in favor of genetically specifying the last few potential connections'.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 2 of 2 citations: 1 supported, 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
