Chapter 20, Problem 4TYK
Summary Introduction
Introduction:
The theory of evolution was proposed by Charles Darwin. Darwin claims that evolution has taken place through the process of natural selection. The organisms that have desirable characters get to survive and reproduce in the environment. The descendent species share a common ancestor and will continue to evolve with the environment. In contradiction, some of the scientists claim that evolution takes place by the process of orthogenesis.

- What is the difference between micro- and macroevolution? a. Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants. b. Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms. c. Microevolution describes the evolution of populations, while macroevolution describes the emergence of new species over long periods of time. d. Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.arrow_forwardWhat is a Homology? A) When an anatomic feature is shared among organisms and their descendants B) When two organisms appear the same C) When convergent evolution produces similar phenotypesarrow_forwardDefine the following terms: divergent evolution, convergent evolution, analogous structures, homologous structuresarrow_forward
