In the paleoTS model set, the Ornstein–Uhlenbeck mode recasts fossil stasis as active mean-reversion toward an adaptive optimum, not a null absence of change

Mean-reversion toward an optimum — the Ornstein–Uhlenbeck process — recurs independently across fossil stasis, bond pricing, and SGD near a loss minimum

Is Sewall Wright's 1932 adaptive landscape a genuinely cited conceptual ancestor of the deep-learning 'loss landscape,' or only a loose after-the-fact resemblance?

Fossil stasis is now a fitted stochastic model — the same Ornstein–Uhlenbeck process that prices bonds and describes SGD near a loss minimum
