Textbook Question
Chapter 23, Problem 8TYK
Adaptive radiations often follow mass extinctions because:
a. mass extinctions limit the impact of paedomorphosis.
b. mass extinctions foster allometry and heterochrony.
c. mass extinctions decimate all forms of life on Earth.
d. species that form transitional fossils often survive mass extinctions.
e. extinctions open adaptive zones that had been previously occupied.

Researchers 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.
Adaptive radiation is common following a period of mass extinction, probably because (a) the survivors of a mass extinction are remarkably well adapted to their environment (b) the unchanging environment following a mass extinction drives the evolutionary process (c) many adaptive zones are empty(d) many ecological niches are filled (e) the environment induces changes in the timing of development for many species
The 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.

- One 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_forwardSeveral 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_forwardAll mammals have tailbones and muscles for moving a tail. Even humans have a reduced tailbone and remnant tail-twitching muscles, though these features have no apparent usefulness. These traits in humans would best be described as (a) convergent structures.
