Abstract Throughout evolution, living organisms have honed the ability to swiftly recognize biological motion (BM) across species. However, how brain processes within‐ and cross‐species BM, evolutionary progression of these processes, remain unclear. To investigate questions, current study examined activity in lateral temporal areas humans monkeys as they passively observed upright inverted human macaque BM stimuli. In humans, middle area (hMT+) responded both stimuli, while right posterior superior sulcus (hpSTS) exhibited selective responses This selectivity is evidenced by an increased feedforward connection from hMT+ hpSTS during processing monkeys, MT region processed stimuli species, but no subregion STS anterior specific conspecific A comparison findings suggests that upstream regions (i.e., MT) may retain homologous functions downstream STS) undergone differentiation specialization throughout evolution. These results provide insights into commonalities differences specialized visual pathway engaged BMs, well their functional divergence
