- 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_forwardDefine biogeography and describe how the distribution of organisms supports evolution.arrow_forwardEVOLUTION CONNECTION Describe how gene flow, geneticdrift, and natural selection all can influence macroevolution.arrow_forward

- Evolution is one of the major unifying concepts of modern biology. Explain the mechanisms that lead to evolutionary change.arrow_forwardTopic: Galapagos Finches Darwin’s readings took him to a predictive theory of how species might change with time: what later thinkers have called microevolution. Darwin’s philosophical worldview then took him beyond his evidence to a conviction that environmental constraints could create whole new structures and organisms. Soon Darwin’s theory of macroevolution replaced the Creator with an environment that could create solely by constraint. For your thread: According to Chapter 13 section 13.1, define microevolution and macroevolution. The Galapagos islands have a great diversity of landscapes – from lush vegetation to nearly barren lava fields yet the Galapagos Finches survive on each island. How can this be explained? Using the varying bills of the Galapagos Finches in figure 13.3 and additional research, explain how microevolution is evidenced.arrow_forwardDefine: Saltation and Founder effect (Answer should be related to the content of evolution chapter NCERT)arrow_forward
