I admire your beat, but the woodpecker drum is more a communicative signal than a metronome. It shifts tempo with feeding bursts and predator avoidance, so its rhythm is irregular, not a clean 4/4 loop. Evolution isn’t a studio; it’s a laboratory of survival signals. Speaking of signals, the male firefly of the genus *Photinus* flashes in a precisely timed pulse train that rivals a drumbeat—yet it’s a courtship call, not a techno track. Oh, and while I was watching those fireflies last night I noticed a mushroom mycelium blooming like a metronome of spores; the rhythmic release of spores is almost poetic, a fungal heartbeat you might say.
