This quiz titled 'Bio 1 - Mechanisms of Evolution' explores key concepts in biology, focusing on evolution. It assesses understanding of biological variation, species classification, vestigial structures, adaptations, and historical scientific theories. Ideal for learners aiming to grasp evolutionary mechanisms.
