Textbook Question
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.

- Scientists classify living things in order to organize the astonishing diversity of life on Earth. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA. Molecular similarities show that organisms are related. In other words, they are descendants of a common ancestor in the past. As we said earlier in our discussion, there are species that needs to be named and some are to be discovered. However, with the current environmental situation we have at the present (pollution, exploitation of resources, forest fires, and others), these species that are yet to be identified are being endangered and at the verge of extinction. As a matter of fact, the University of Turku reported last July 1, 2020 that there are 15 million estimated different species living in our planet but 2 million of them are currently known to science. Discovering these remaining species is important for them to be protected. Also,…arrow_forwardWhat are sister groups? Two groups of closely related organisms that share a common ancestor Two groups of distantly related organisms that share a common ancestor Two groups of organisms that look similar but are actually not related Two groups of closely related organisms that do not share a common ancestorarrow_forwardA population of insects is composed of individuals with red bodies and individuals with yellow bodies. A storm moves a small group of red insects to a new location where they thrive as a new population. What has occurred in the new population?* Bottleneck effect Sympatric speciation Founder effect Temporal isolation All living organisms use DNA and RNA as their genetic code roundworms, in fact, have 25% of their DNA in common while humans and chimpanzees have 98% in common. What type of evidence of evolution is this? * Comparative embryologyarrow_forward
- Which of the following is the best definition of a major transition in evolution? Individuals evolve traits the help them fight off rivals Formerly independent replicating individuals form a collective that reproduces together A group of individuals evolve traits that help them individually forage better Individuals evolve traits that allow them to colonize a new environment.arrow_forwardWhat is an evolutionary tree? Is there a precise evolutionary tree that explains the emergence and origin of every type of living organisms?arrow_forwardhow do scientists support the theory of evolution? use the terms evolution, natural selection, vestigial structures, homologous structures, DNA, adaptations and fossilarrow_forward
- The process of industrial melanism and the beaks of Darwin's finches are examples of what process producing evolutionary change? Selected Answer: artificial selection Answers: founder effect artificial selection intelligent design natural selectionarrow_forwardWhat 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 organisms in populations, while macroevolution describes the evolution of 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_forwardWhich statement about genome evolution is false? Mutations at the ends of introns are less likely than in the middle of an intron. Synonymous mutations rates are much higher than nonsynonymous mutation rates. Psuedogenes show high rates of mutations. Comparison of the mutational change in a specific gene can be used as a molecular clock to date evolutionary events between species. Evolution in a gene sequence will occur the fastest in regions that have the greatest effect on function.arrow_forward
- Vestigial structures are: structures that were helpful to our ancestors but do not serve any useful purpose under current conditions structures that are only helpful when there is competition for survival structures that are harmful relics of our evolution structures that appear to contradict our understanding of how evolution works O000arrow_forward1) How have scientists created the "tree of life"? Do you think that variations exist between these created trees? 2) What are the pros and cons to creating a "tree of life"? 3) When constructing this tree of life we can see many dead ends or organisms that we are unsure of their exact placement. Why is this? 4) Choose one species (either alive today or extinct) and describe its taxonomic classification. What traits or characteristics were used to classify this species into its current taxonomic classification? What other organisms are considered to be its closest relatives?arrow_forwardMale bowerbirds construct elaborate nests in order to attract females. Different species of bowerbirds often live in the same area, yet they will not mate with each other because of the females' strong preferences for a particular kind of nest. What does this exemplify? convergent evolution reproductive isolation homologous structures geographic isolationarrow_forward
