- Conway's Law
- Developmental biology — body-plan modularity tracks the modular decomposition of gene-regulatory networks; segments, limb fields, and organ systems are the phenotypic image of regulatory modules whose internal connectivity is dense and between-module connectivity sparse.
This sourceBody-plan modularity tracks the modular decomposition of gene-regulatory networks — dense within-module, sparse between-module connectivity — the biological analogue of the producer-to-artifact imprint. (

The abstract supports modularity of the genotype-phenotype map with pleiotropy concentrated within single functional complexes, but says nothing of gene-regulatory networks, segments, limb fields or organ systems.
“A common result for organismic design is modularity. By modularity we mean a genotype-phenotype map in which there are few pleiotropic effects among characters serving different functions, with pleiotropic effects falling mainly among characters that are part of a single functional complex. Such a design is expected to improve evolvability by limiting the interference between the adaptation of different functions.”

- Gall's Law
- In biological evolution and evolvability theory, Darwinian selection requires each ancestral form to be viable in its own environment, so a complex organ implies a chain of functional intermediate organs each useful at the time; evolvability research formalizes this as connectivity of the viable region of genotype-space.
This sourceFormalizes evolvability in terms of the connectivity of the viable region of genotype space, requiring each ancestral form (and intermediate) to be viable for selection to traverse a path.
Supported in partVerified against the publisher's abstract
The abstract supports evolvability's dependence on the genotype-phenotype map, but nowhere states connectivity of a viable region of genotype space or the requirement that each ancestral form be viable.
“For adaptation to occur, these systems must possess "evolvability," i.e., the ability of random variations to sometimes produce improvement. It was found that evolvability critically depends on the way genetic variation maps onto phenotypic variation, an issue known as the representation problem.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 2 of 2 citations: 2 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.
