Exploring Extinct Species: Coexistence with Early Homo
Extinction: An Evolutionary Dead-End in Human Evolution

Extinction: An Evolutionary Dead-End in Human Evolution

Introduction: The extinction of various hominin species has significant implications for our understanding of human evolution. Approximately one million years ago, numerous species cohabited with early Homo species before becoming extinct. Understanding these evolutionary dead-ends contributes to our knowledge of adaptive traits, survival strategies, and the ecological dynamics that influenced the evolutionary paths of modern humans. This article examines the extinction of these early species, their coexistence with Homo, and their roles in the broader framework of human evolution.
