Molecules in million‑year‑old fossils show a warmer, wetter past

Researchers extracted metabolism molecules from fossil bones aged 1.3–3 million years. Analyses of animal and plant metabolites reveal diets, infections and local environments and suggest the study sites were warmer and wetter than today.
