The analysis of DNA extracted from ancient specimens throughout history, known as ancient DNA (aDNA), has revolutionized evolutionary biology since its inception in the 1980s. The discipline provides scientists with a method to study genetic modifications by analyzing discovered DNA from ancient beings and historic biological samples. aDNA research faced substantial technical obstacles and trust issues before becoming an essential academic field between palaeontology, genomics, and evolutionary biology by advancing its methods and technology. This article investigates the development chronology of aDNA investigation, its essential analytical procedures, and important breakthroughs. Through its analysis of extinct species' phylogenetic connections and discoveries about ancient hominin population activities and mating histories, aDNA has proven itself as a tool that challenges established evolutionary beliefs. The advancement of next-generation sequencing technology provides scientists with two breakthroughs, including the complete genome sequencing of ancient specimens and the ability to study their functional components. The expansion of environmental DNA technology and analytical sophistication increases the power of aDNA research to deliver unparalleled information regarding evolution and extinction, as well as environmental adaptation. These recent breakthroughs help us understand our biological history and supply crucial knowledge to conservation biology during times of accelerating environmental change. Ancient genomics, when combined with paleoclimatology, archaeological research, and functional genomics, will enhance our understanding of the evolutionary patterns of all living organisms.
