This article illuminates the transformative contributions of Khasan Alpysbayev to archaeological science in Kazakhstan and Central Asia, particularly through his pioneering research on Paleolithic sites. His systematic excavations and integration of key locations such as Borykazgan and Suleymensay redefined regional prehistory and anchored Kazakhstan within the broader archaeological narrative. Utilizing multidisciplinary methods–stratigraphy, morphological analysis, and topographic mapping–Alpysbayev advanced scientific rigor and methodological innovation in Paleolithic studies. The discussion highlights his foundational role in shifting archaeology from a peripheral pursuit to a central scholarly discipline in Kazakhstan. Through discoveries like the Karatau detachment and Ak-Chunkur cave, he significantly enriched understanding of early human history in Central Asia. The results and conclusion affirm his enduring legacy: the establishment of a national archaeological school, mentorship of emerging scholars, and elevation of Kazakhstan’s global archaeological stature. Alpysbayev remains a monumental figure, whose intellectual vision continues to shape contemporary research and heritage preservation.
