Clarifying Misconceptions of the Zone of Latent Solutions Hypothesis: A Response to Haidle and Schlaudt: Miriam Noël Haidle and Oliver Schlaudt: Where Does Cumulative Culture Begin? A Plea for a Sociologically Informed Perspective (Biological Theory 15: 161-174, 2020).

Abstract

The critical examination of current hypotheses is one of the key ways in which scientific fields develop and grow. Therefore, any critique, including Haidle and Schlaudt's article, "Where Does Cumulative Culture Begin? A Plea for a Sociologically Informed Perspective," represents a welcome addition to the literature. However, critiques must also be evaluated. In their article, Haidle and Schlaudt (Biol Theory 15:161-174, 2020. 10.1007/s13752-020-00351-w; henceforth H&S) review some approaches to culture and cumulative culture in both human and nonhuman primates. H&S discuss the "zone of latent solutions" (ZLS) hypothesis as applied to nonhuman primates and stone-toolmaking premodern hominins. Here, we will evaluate whether H&S's critique addresses its target.
