“…But as soon as we move up a notch in abstraction, to more broadly scoped gestures-gesture families, recurrent gestures, and gestural practices-we begin to see striking similarities across cultures. For example, several prominent recurrent gestures recur across groups (e.g., Bressem, Stein, & Wegener, 2017); the palmup epistemic gesture is a broadly shared pairing of form and meaning (Cooperrider, Abner, & Goldin-Meadow, 2018); and many conventional negation gestures are strikingly widespread (see, e.g., Inbar & Shor, 2019;Mesh & Hou, 2019). We might say, borrowing Darwin's words, that these gestures seem too widespread to be thought of as "altogether conventional or artificial" (Darwin, 1872, p. 274).…”
