Chapter 21.6, Problem 2LO
Summary Introduction
To determineThe demonstration of how the biological distribution of plant and animal species on islands provides evidence of evolutionary diversification.
Introduction: Convergent evolution refers to the process in which different organisms or species evolve similar characters or traits independently. Different types of evolutionary processes like genetic drift, natural selection, and mixture leads to the evolution of a species.
