Geographic distribution of the samples investigated in this study. (A) Summary map of all specimens, including those previously and newly sequenced. Shapes and colors are consistent with those used in the various figures, and reflect the different population groups, in line with those from previous publications. (B) Summary map of the specimens newly sequenced in this study. Sample labels include first a name, followed by a three-letters code referring to their country of origins, and the midpoint of the radiocarbon date in calibrated years B.P. (INF is shown for specimens associated with infinite radiocarbon measurements). For clarity, a single annotation is indicated in locations where multiple specimens were analyzed. In such cases, labels indicate the number of specimens (#) and provide their radiocarbon range (see table S1 for individual information). (C) Same as (B), for the specimens previously sequenced and used as a comparative panel. Credit: Science (2025). DOI: 10.1126/science.adr2355

(a) Geometry of the incoming fields, electro-optic crystal (EOX), and the evolution of the polarization state of the gate pulse. (b) A typical setup for EOS with a femtosecond laser. The near-infrared (NIR) laser output in the form of short pulses (blue) is split by a beam splitter (BS) into the “test” and “gate” beams. The longwave test waves (red), produced, e.g., by optical rectification of the laser output, are combined with the gate pulses (the laser output pulses) and are analyzed via ellipsometry. OAP: off-axis parabolic mirror; GX: crystal for generating test waves; SF: long-pass spectral filter; BS: beam splitter/combiner; VD: variable optical delay line; EOX: electro-optic crystal; 𝜆/4: quarter-wave plate; WP: Wollaston polarizer; BPD: balanced pair of photodiodes. (b) is adapted from Ref. 23. Credit: Optica (2025). DOI: 10.1364/OPTICA.544333
