Chapter 19, Problem 4RQ
What is the difference between micro- and macroevolution?
- Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants
- Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms
- Microevolution describes the evolution of organisms in populations, while macroevolution describes the evolution of species over long periods of time
- Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.

Group of answer choices The 14 finch species originated from 14 different ancestral species that all arrived to the Galapagos over a relatively short time period. The 14 finch species originated over a relatively short time period from a single species. The 14 finch species most likely originated as a result of polyploidy. The 14 finch species on the Galapagos Islands are actually not a good example of adaptive radiation. The 14 finch species evolved their characteristics separately as a result of convergent evolution.arrow_forward

- . The Process of Evolution by Natural Selection – Be able to explain the process of evolution by natural selection as it applies to a specific living thing using the outline below: Natural variations caused by random mutations (adaptations) in DNA exist within populations. Those with helpful adaptations survive an environmental change (maybe a predator.) The survivors breed, passing on the inherited mutation (adaptation) to offspring. The resulting population has more of the successful inherited mutation (adaptation) than the original population. Phylogenetic Trees Infer evolutionary relationships of living things by interpreting phylogenetic trees. Know the divisions of hierarchical classification. (DKPCOFGS) c. Differentiate between homologous and analogous (caused by convergent evolution) structuresarrow_forwardhow do scientists support the theory of evolution? use the terms evolution, natural selection, vestigial structures, homologous structures, DNA, adaptations and fossilarrow_forwardA group of one species of bacteria are exposed to an antibiotic. The normal bacteria die but some are resistant to the antibiotic and start multiplying. The resistant bacteria flourish and now make up the majority of the population. This is an example of what?
