But we note that more research on this topic would be very helpful to understand the magnitude of this risk. :-) For more info please feel free to check our discussion: www.nature.com/articles/s41...

The original paper is open access and we touch on this in the discussion briefly. Mainly, we argue that upregulating exploration to compensate for small diets (that lacked cultural input during development) in adulthood is likely risky due to inedible/toxic foods in the environment, (1/2)

This suggests that early hominin cultures were more expansive than can be predicted from surviving artifacts alone, including key information used for daily decision making.

Whilst accumulating culturally-dependent expanses of knowledge is a key facet of humans' generative and open-ended cultures, our results suggest that this capacity is likely ancestral to (at least) great-ape species.

In extension, we evidence that the breadth of cultural knowledge possessed by orangutans is likely more expansive than any one individual could produce independently (thus, a 'culturally-dependent repertoire').

We show that cultural transmission is essential for orangs to learn basic subsistence information in the wild. The repertoire of cultural information possessed by apes is likely to be far more expansive than social customs and highly technical skills, including simple info about 'what to eat'.
