A New York Times article reports on ancient fossils indicating handedness. Researchers found right‑biased traits in species predating hand evolution. The study suggests behavioral laterality emerged early in animal history. Findings challenge assumptions that handedness requires manual dexterity. The article explains the methods used to detect asymmetry in fossils. Experts discuss implications for understanding brain development. The discovery adds a new dimension to evolutionary biology debates. Future research may explore how early laterality influenced later species.
