- explain the following mechanism of evolution: 1. mutations 2. gene flow 3. genetic drift 4. sexual selection 5. natural selectionarrow_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_forwardHELParrow_forward

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_forward
- CONNECT In what way does the modern synthesis strengthen scientific understanding of evolution? (a) is based on the sequence of fossils in rock layers (b) uses genetics to explain the source of hereditary variation that is essential to natural selection (c) was first proposed by ancient Greek scholars (d) considers the influence of the geographic distribution of organisms on their evolution (e) is reinforced by homologies that are explained by common descentarrow_forwardEVOLUTION LINK Write short paragraphs explaining each of the following statements: (a) Natural selection chooses from among the individuals in a population those most suited to current environmental conditions. It does not guarantee survival under future conditions. (b) Individuals do not evolve, but populations do. (c) The organisms that exist today do so because their ancestors had traits that allowed them and their offspring to thrive. (d) At the molecular level, evolution can take place by the replacement of one nucleotide by another. (e) Evolution is said to have occurred within a population when measurable genetic changes are detected.arrow_forwardWhich of the following ideas proposed by Charles Darwin provided the first objective way to measure small evolutionary changes from one generation to the next? common descent biogenesis evolution abiogenesis populational changearrow_forward
- Discuss the process of evolution through natural selection. What could happen to the ecosystem and animals in ten, one hundred, or one thousand years? Is it feasible for them to continue evolving or do they eventually become extinct? Explain your answer concisely.arrow_forwardMechanisms of evolution include (check all that apply) Natural selection Genetic drift Genetic variation Mutation Gene flow and migrationarrow_forwardMany creationists will allow that microevolution (for example,changing gene frequencies in a population) has occurred, and will even acknowledge that species adapt to different environments. However, they deny that macroevolution (they define it as the evolution of new “kinds”) is supported by evidence. Explain how they are mistaken. How might you help a creationist friend better grasp how modern scientists consider micro- versus macroevolution?arrow_forward
