The article now attributes this wording narrowly to Nozick, marks its 10-unit calculation as an original conditional illustration, and limits the resulting recommendation to an unrestricted additive total-utility rule under explicit assumptions. The Stanford Encyclopedia supports distinctions among classic total-utility utilitarianism and other consequentialist approaches. Chappell’s accessible Cambridge abstract distinguishes a later negative-utility variant; the full article was not accessed. The IEP entry supplies rights-based context but does not discuss Nozick’s monster. A read-only post-edit reviewer found no material corrections. The article and dataset reference URL sets match; date_verified is 2026-11-01.",

The Royal Society record confirms publication details and abstract, while its full text remains paywalled. The article now explains that Gould and Lewontin use the San Marco architectural spaces to illustrate why current utility alone does not establish origin, and it avoids claiming that natural selection is rejected. Gould’s full 1997 clarification supports the qualification that his byproduct claim concerned the pendentives’ necessary number and shape, not absence of structural utility, and that extending ‘spandrel’ to those 3-D structures has been debated. Gould and Vrba’s 1982 paper supports the later term exaptation and its distinction from adaptation. A read-only post-edit review found no material corrections.
