I actually thought of an interview Lex Fridman had with a sleep researcher (probably this one, https://lexfridman.com/andrew-huberman-2/) about how temperature is a good signal for distributed coordination just before Webster brought up dinosaurs. This is exactly the kind of thing I've been thinking about lately: living systems have all sorts of thresholds like this and we don't know how many of them we're just sidling up to.
