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.
b.
ecological opportunity.
c.
morphological innovation.
d.
behavioural 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_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_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_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_forwardAdaptive radiation is when populations diverge from a common ancestor into new species, each of which is adapted to its own unique niche. Provide evidence to highlight an example as to how this may have occurred in some of the species of penguins.arrow_forwardThe graph below shows the population of three different families of marine organisms along five different mass extinction events. Each colour on the graph represents a family of organisms, and the Y axis shows how many species belong to that family. a. What stage of population growth is displayed at point ‘0’ on the graph above? b. The Extinction Event that occurred at point 3 was particularly significant. Using the graph, explain how this event impacted each marine family. c. The extinction events mapped above had significant impact on marine life. What type of event could have a similar impact on the human population?arrow_forward
- Assume you are studying the fossil record of a certain lineage of sharks.
