Textbook Question
Chapter 25, Problem 4TYK

Students have asked these similar questions
a. What did Darwin's travels reveal to him about the number and variety of living species?
b. How did tortoises and birds differ among the islands of the Galapagos?
c. What is evolution? Why is referred to as a theory?
d. Darwin found fossils of many organisms that were different from any living species. How
would this finding has affecting his understanding of lifes diversity?
Which of the following most likely demonstrates that classification is the basis of evolutionary relatedness?
A. Organisms that share similar characteristics are impliedly understood to have common ancestors, thus having an evolutionary relationship.
B. Classification is to organize organisms into groups based on their differences and similarities and evolutionary history, so as evolution changes, classification will also change
C. Classification based on evolutionary relatedness always infer that all organisms that evolved similarly shares the same history.
D. Homologous structures among organisms depicts the same evolutionary history or paths.
The Theory of Evolution contends that species have changed through time and are related to one another through descent from a common ancestor. Which of the following prediction follow from the Theory of Evolution?
A. The fossil record should contain intermediate forms between major taxonomic groups
B. The oldest rock strata are much more likely to contain complex fossils than simple fossils.
C. Fossils are always a representation of species that are currently alive (ie extant) even if they have not been detected yet as living on earth at the present time
D. All species are unigue and originated independently from each other

- Several very distantly related species (e.g., bats, birds, insects) have evolved the capability of flight. The most recent common ancestor of insects and vertebrates likely lived over 500 million years ago and was flightless. This independent evolution of flight in multiple, distantly related taxa is an example of what evolutionary process/pattern? a. Evolutionary reversal b. Convergent evolution c. Speciation d. Synapomorphyarrow_forwardAssume you are studying two different species of plants that have evolved purple flowers. You reconstruct the ancestor of these plants and discover the ancestor plant had pink flowers. You decide to investigate the development of the purple flowers and find that the plants both evolved purple flowers via the same purple pigment gene pathway.

Convergent Evolutionarrow_forwardAll the following statements support the theory that similar organisms have a common ancestor except Select one: a. similar DNA patterns occur in closely related organisms b. organisms sharing a habitat tend to develop similar behaviours c. transitional fossils show links between groups of organisms d. groups of organisms display similar embryonic developmentarrow_forward

- What consequences does horizontal gene transfer pose for evolutionary biologists? a. It can pose difficulty in the reconstruction of phylogenetic trees, because it can obscure phylogenetic relationships. b. It can pose physiological problems in some organisms, making it very hard to study them. c. It can pose difficulty in breeding between different individuals of the same species. d. Because it is transfer of genes between the same species, it can make individuals look very more similar than they actually are. e. All of the above.arrow_forward1. Which is a more definite characteristic to show relatedness of two organisms? A. Similarity in development B. Similarity in courting behavior 2. Why do organisms with close biochemical similarities show stronger evolutionary relationships? A. They have varied and different ancestry. B. They have a common ancestor and have the same kind of proteins. C. They possess same vestigial structure that made their evolutionary. D. They have similar patterns during their early stages of development. C. Similarity in structure D. Similarity in genomic DNAarrow_forwardWhat is true about evolution by natural selection? a. It is a largely random process. b. Homology shows that convergence is a useful tool for deducing adaptive function. c. Mothers are invariably members of the same species as their offspring, so selection can never create new species. d. Harmful recessive genes are eliminated more rapidly than harmful dominant genes. e. None of the above is true.arrow_forward

C. that have evolved after the last common ancestor of a particulan collection of species. D. that are less well suited to the environment than ancestral characters.arrow_forwardThe three beetle species live in the same ecosystem, and they likely evolved from the ancestral species that colonized the region. Which statement best explains how descent with modification influenced speciation in these beetles? A. The ancestral species carried neutral gene mutations that spontaneously caused speciation when they colonized the region. B. The ancestral species randomly diverged into three species before colonization and then colonized the regions that best suited their new adaptations. C. After colonization, small groups separated from the rest of the ancestral species and developed different adaptations that helped them survive and reproduce. D. After colonization, the large group interbred until they developed enough neutral genetic mutations for speciation to occur.arrow_forward
