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
Adaptive radiations can be a direct consequence of three of the following four factors. Select the factor that is NOT a direct consequence of adaptive radiation.
Select one:
a. Genetic drift
b. Vacant ecological niches (niches are environment "space" where a particular organism has resources required to survive and reproduce)
c. New evolutionary innovations
d. Colonization of a new region that contains suitable habitat and few competitor species
The adaptive radiation of mammals following the extinction of the dinosaurs is an example of adaptive radiation due to
a.
physiological innovation.

- After the mass extinction that occurred 65 million years ago, mammals rapidly diversified to occupy habitats that were previously unavailable to them. What concept does this illustrate? A. Adaptive radiation B. Cretaceous selection C. Reproductive isolationD. Heterozygote advantagearrow_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_forwardWhich hypothesis is plausible for the extinction of the dodo bird? Select all answers that apply. A. The food and other resources they required became scarce due to climate change. B. An asteroid crashed into the region where the birds lived and only affected their survival and not the other animals that lived there. C. Cannibalism within the species caused the population to decline. D. Each bird dove into the water even though it could not swim, which led to mass drownings. U E. Predators, including humans, hunted and killed the population to a point that it could not recover. red MacBook Air 80 F3 F1 DO0 F4 F2 F5 F7 % & %24 23arrow_forward
- Species that are more vulnerable to certain risk factors are more likely than others to become extinct. For example, species with a unique lineage, such as the giant panda, are likely to be at severe risk of extinction.a. Should our limited resources for species protection be focused on species that are at the highest risk of extinction?b. Do you support the idea that high-risk species may be less successful products of evolution and should not receive extraordinary protection?arrow_forwardAssume 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_forwardAccording to " Denisovans: Decoding the Secrets of Our Mysterious Ancient Cousins”, what is the most likely reason that the Denisovans became extinct? A.Homo sapiens expanded into the territories that Denisovans lived, and used up the food and land resources in that area. B.Woolly mammoths expanded into the territories that Denisovans lived, and used up the food and land resources in that area. C.Predators expanded into the territories that Denisovans lived, and they killed off the Denisovans. D.Homo sapiens expanded into the territories that Denisovans lived, and killed off the Denisovans.arrow_forward
- The Galapagos archipelago consists of volcanic islands that formed within the last 5 million years.

The Galapagos finches are an example of adaptive radiation driven by a. behavioural innovation. b. morphological innovation. c. ecological opportunity. d. physiological innovation.arrow_forwardA. The principle that human biology and culture evolved together and are intertwined makes anthropologists refer to humans as: a. biocultural organisms. b. an holistic species. c. human agents. d. co-specific organisms.

Which of the following is likely to occur? A. Genetic diversity will decrease on the mainland, because of a population bottleneck. B. Alleles that were more rare on the mainland are likely to become more common on the island, because of the founder effect. C. Genetic diversity will be lower on the island than the mainland, because of the founder effect. D. Mutations rates will increase on the island, in response to selection pressures in the new environment.arrow_forwardIf two lava flows are separated by a short distance (say, less than a kilometer), how could both lava flows come to be occupied by dark colored mice? (Select all correct answers) O A. Dark mice could evolve on one lava flow, then migrate and colonize the other lava flow. B. Dark coloration could evolve independently on each lava flow. C. Genes for dark coloration could evolve on one lava flow, then move to the other lava flow through interbreeding of dark mice with light mice on the other lava flow. D.A large population of dark mice could spontaneously be generated simultaneously on the dark lava flows.arrow_forward
