 A common two-pronged response to this distinction (e.g., Sterelny 1996) has been to concede the reality of superorganismic group selection (but underscore its rarity) and argue that instances of trait group selection are better described as cases of genic or individual selection relativized to a particular environment, where part of that environment is composed of other individual organisms (see also Okasha 2006, 2018). In effect, this is to allow for superorganisms as a special kind of biological individual, but to reject a more expansive conception of evolutionary individual at the group level. On this view, eusocial insects may be evolutionary (and even physiological) individuals, but trait groups are neither.
