Adaptation CORRECT ANSWER Inherited characteristic of an organism that enhances its survival and reproduction in specific environments Natural selection CORRECT ANSWER A process in which organisms with certain inherited characteristics are more likely to survive and reproduce than are organisms with other characteristics. Artificial selection CORRECT ANSWER The selective breeding of domesticated plants and animals to encourage the occurrence of desirable traits Observations of change, f...

GMO (genetically modified organism) - An organism whose DNA has been deliberately altered. Made possible by Recombinant DNA technology. Evolution - Change in a population or species over generations Microevolution - Change in allele frequencies in a population over generations. Macroevolution - Evolution at or above the species level Charles Darwin - Father of evolution Darwin's Theory of Evolution - Species living today descended from a single ancestral species. Two main components are ...

BIO 103 Final Study Guide (18, 23, 24, 25, 26) Questions and Answers 100% Pass What is a change that occurs in an organism over time to enhance its survival and reproductive success? An evolutionary adaptation. What causes similarities in characteristics between different species? Homoplasy, which is the result of convergent evolution rather than common descent. What allows a population to change over time? Natural selection. What are two geological processes common ...

Evolution Questions and Answers (Complete and Certified) Evolution(Macroevolution) Gradual change of organisms over very long periods of time. Types of Evolution- Coevolution, Convergent, and Divergent(Adaptive Radiation) Coevolution- change of 2 different species in close association to each other.(Predator/Prey) Convergent- 2 different organism have similar phenotypes because of the environment.(ex. Dolphin and Shark) Divergent(Adaptive Radiation)- 2 or more of the same species become dissimi...

convergent evolution - unrelated or distantly related organisms evolve similar body forms, coloration, organs, and adaptations natural selection - the process whereby organisms better adapted to their environment tend to survive and produce more offspring (acts on individuals but populations evolve) Judeo- Christian perspective - The Creator: God made everything Linnaeus - Binomial nomenclature and nested classification system Cuvier - fossils in strata- catastrophism Hutton and Lyell - g...
