Abstract
Abstract
Genetic diversity is a fundamental component of evolutionary biology, shaping the adaptive capacity, resilience, and longterm
survival of species. Present study investigates the relationship between genetic diversity and evolutionary processes
through an integrated approach combining primary and secondary data. Primary data were collected by using a structured
questionnaire administered to 50 respondents to evaluate awareness and perceptions of genetic variation and its evolutionary
significance. Secondary data were obtained from peer-reviewed scientific literature and publicly available biodiversity and
genetic databases, including the International Union for Conservation of Nature (IUCN) Red List Database, World Wildlife
Fund (WWF) Living Planet Reports, National Center for Biotechnology Information (NCBI) Gen Bank, the Food and
Agriculture Organization (FAO) genetic resources databases, and published population genetic studies indexed in Google
Scholar, Scopus, and Web of Science.
The findings indicate that 40% of respondents exhibit high awareness of genetic diversity, while 35?monstrate moderate
awareness, and 25% show limited understanding. Secondary data reveal variation in genetic diversity indices across taxa,
with plants exhibiting the highest diversity (~80%), followed by birds (~70%), mammals (~65%), and reptiles (~55%). These
patterns reflect differences in reproductive strategies, population structures, and evolutionary pressures
