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
Which of the following is a prediction that evolution makes about the fossil record? Group of answer choices A. fossils of all time periods should be completely different from modern organisms B. most recent fossils should be most similar to modern life C. cats should appear in all fossil layers as rulers of the earth D. oldest fossils should be most similar to modern life
All 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 development
Using radioactive isotopes to determine the age of a fossil is known as radiometric dating. How might radiometric dating provide support for the theory of evolution by natural selection? Hint—Consider the age of fossils with respect to the overall fossil record (the entire collection of data regarding fossils and the age of Earth).
The fossil record provides evidence for: A.When organisms lived on earth B. How some species have gone extinct C.How species evolved D. All of the above
What characteristic(s) of the fossil record make(s) it strong support of evolution? a) It has fossils of many species in it that are not found on earth today. b) It is has a complete record of every form of life ever existing c) Species appear in sediment layers in a consistent pattern d) All fossils are similar to living forms found in the same area as the fossils Group of answer choices A. b and d B. a and b C. c and d D. a and c E. b and c
An analysis of a phylogeny that displays data about the fossil record over time reveals all of the following EXCEPT A. Several extinction events occurred. B. Evolution results in a clear directional pattern. C. Evolution is the result of interactions between organisms and their environment. D. Evidence of continental drift exists.
The evidence supporting biological evolution includes A. all of the above B. patterns of embryological development C. sharing of charactoristics between organisms D. fossil record
Through _______, a body part of an ancestor is modified differently in different lines of descent. a. homologous evolution c. adaptive divergence b. morphological convergence d. morphological divergence
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.
Which of the following is an accurate point that supports the idea that the earliest protocells relied first on RNA (not DNA) as inherited information? A. RNA is composed of lipids, and lipids were present on early Earth before the nucleotides that compose DNA were B. RNA is a monomer (unlike DNA), so it is simpler and more likely to have been used by these simple protocells C. DNA would have been too large to fit into the small protocells, but RNA was small enough to fit D. RNA can serve dual roles as both genetic information storage and an enzyme (but DNA cannot do both) ..
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.
