Evolutionary theory predicts that species are related, not independent. Four of the following examples provide support for this prediction, but one is irrelevant. Which of examples listed below does not support the claim that species are related?
A.
Many dinosaurs and other organisms went extinct following a huge asteroid impact at the end of the Cretaceous.
B.
Before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease.
C.
The endostyle of lancelets (invertebrate chordates) and the thyroid gland of vertebrates develop similarly, and both produce iodinated proteins.
D.
All prokaryotes and eukaryotes use DNA to carry their genetic information.
E.
Ground squirrel species found on the North and South sides of the Grand Canyon are very similar to 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.
Synapomorphy

They are only inherited if they occur in a sperm or egg cell.d. They often occur when DNA is copied.arrow_forwardResearchers have found fossils of Eocene horse species in Colorado. Deeper deposits contain smaller species, and more recent deposits contain larger species. How does this observation support the theory of evolution? A. It provides evidence that species change over time. B. It does not support the theory of evolution. C. It shows that all species are related to each other. D. It proves that environments have changed over time. E. It suggests that species are unchanging and of recent origin.arrow_forwardWhich of the following best reflects a phylogenetic relationship between chimpanzees and baboons? A.

- Which of the following are biological adaptations that have evolved out of the limitation for organisms to maintain a high surface area to volume ratio in different tissues? A. The need for single-celled organisms to remain small. B. The need for organ systems to be branched, have infoldings, and multiple cells. C. The need for large multicellular organisms to have cells that operate at lower metabolic rates. D. All of the above E. A and B onlyarrow_forwardYou have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity:arrow_forwardWhich of the following pairs of structures is least likely to represent homology? Group of answer choices A. The mitochondria of a plant and those of an animal. B. The wings of a bird and those of an insect. C. The hemoglobin of a baboon and that of a gorilla. D. The brain of a cat and that of a dog. E.

- What is an example of evolutionary mismatch in modern day humans? A. Evolutionary mismatch is not a real concept. B. Fatty and sugary foods were disadvantageous for early humans to eat, and they are overly abundant in modern times and contribute to obesity in modern humans. C. Fruits and vegetables were disadvantageous for early humans to eat, but they are healthy for modern humans. D. Fatty and sugary foods were advantageous for early humans to eat, but they are overly abundant in modern times and contribute to obesity.arrow_forwardSome epileptic conditions are due to neurons firing too often.

- Assume you are studying the fossil record of a certain lineage of sharks. You find that sharks in this lineage will maintain the same morphology for long periods of time and only rapidly change their morphology during a speciation event. The evidence you uncover is supportive of which of the following theories? a. Punctuated Equilibrium b. Gradualism c. Start and Stasis d. Increased Net Tempoarrow_forwardOne hypothesis for the Cambrian explosion was an increase in predator-prey relationships. It is thought that the resulting co-evolution of predator and prey may have been a factor in the rapid speciation of animals seen during this time. What findings in the fossil record would most support this? Group of answer choices a. increased incidence of larger-bodied animals b. increased incidence of sessile animals c. decreased incidence of animals with bilateral symmetry d. increased incidence of animals with radial symmetry e. increased incidence of shells, bony plates, spines, and/or clawsarrow_forwardThe 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 otherarrow_forward
