 In the laboratory, the hierarchical genetic approach of multilevel selection has been used to demonstrate that populations respond rapidly to experimentally imposed group selection, and that indirect genetic effects are primarily responsible for the surprising strength and effectiveness of group selection experiments, contra the full equivalence claims (Goodnight 2013; Goodnight &amp; Stevens 1997; cf. West, Griffin, &amp; Gardner 2007, 2008). Field studies using contextual analysis have shown that multilevel selection is far more common in nature than previously expected (Goodnight 2013; e.g., Stevens, Goodnight, &amp; Kalisz 1995;Tsuji 1995; Aspi et al. 2003; Weinig et al. 2007; Eldakar et al. 2010; Wade 2016). There is much less emphasis on the evolution of altruism within the hierarchical genetic approach, as selection is observed as it is occurring, and this includes group selection going in the same direction as organismic selection, not just in opposition to it, contra early genic selectionist recommendations (Maynard Smith 1976). This sort of group selection of interactors is not based on group level engineering adaptations, although some still persist in confusing group selection itself with the combination of the two features, group selection and group engineering adaptation (e.g., Ramsey &amp; Brandon 2011).
