Electron paramagnetic resonance (EPR) spectroscopy, also called electron spin resonance (ESR) or electron magnetic resonance (EMR) measures the absorption of microwaves by paramagnetic centers with one or more unpaired electrons.1–5 A single unpaired electron (S = 1/2) can have two possible spin states, ms = ±1/2, that are degenerate in the absence of an external magnetic field.
Earlier research had suggested a later date; the problem is the dating of the archaeological sites where their remains have been found. Neanderthals perhaps evolved from Homo heidelbergensis and split off (last common ancestor) from modern humans between , and , years ago.
