Bio 100 Exam 3 (Jaeger UNLV) Questions and Answers 100% Pass **Evolution is defined as** any change in the phenotype of a population over successive generations due to genetic factors. **Common Descent with Modification entails** species undergoing modifications across generations. These changes can lead to the emergence of new, distinct species. **Species are** various types of organisms. Individuals within the same species share genetic similarities and can potentially interbre...
