Tracing Human Evolution through Ancient DNA: Insights from Paleogenomic Studies

Abstract

This paper evaluates groundbreaking innovations in reconstructing human history through the
lens of ancient DNA. Employing paleogenomic techniques, scholars have mapped genetic
branches, population migrations, and admixture events spanning tens of millennia. This research
focuses on the developments of sequencing technologies and comparative genomics of
Neanderthals, Denisovans, and early Homo sapiens. Current data attest to complex interbreeding
and regional adaptive distinctness. Such studies not only refine human ancestry but also
illuminate the path of how genetic variability shapes evolutionary theory.
