Many-eyes and sentinels in selfish and cooperative groups. PNAS. 2026;123(33):e2536017123. doi:10.1073/pnas.2536017123 Lyrics: Verse 1 In the hush of a restless edge, Eyes trade time like borrowed light, Every glance a tiny pledge, Against the dark that hunts the night. Pre-Chorus If the price of looking rises fast, We share it thin, we spread it wide, But if the cost can soften past, One brave gaze becomes our guide. Chorus Many eyes, low and steady—hold the line, Or one sentinel, burning bright, a single sign, Convex or concave, the choice is drawn in code, In the curve of what we spend, in the weight of what we owe. Verse 2 Selfish hearts or hands aligned, Still the math keeps time the same, When the threat shifts, we redraw the line, And switching feels like changing flame. Bridge Not every body pays alike—there’s an edge that pulls and bends, Energy runs in circles, so the lookout role can spend, Take your turn, then trade it back, let the tired ones descend, A rotating crown of caution where the night and daylight blend. Final Chorus Many eyes, low and steady—hold the line, Or one sentinel, burning bright, a single sign, It’s not just will, it’s how the cost becomes the load, In the curve of what we spend, we find the way we hold.
