Exam 14: How Biological Diversity Evolves

The biological species concept cannot be applied to ________.

One means of reproduction called budding occurs when a new organism develops as an outgrowth of its parent (singular). Could organisms that develop by budding be defined by the biological species concept?

Which taxonomic level is most inclusive?

Dinosaurs (aside from the lineage that produced birds)were extinct by the end of the ________.

A reproductive barrier that prevents individuals from closely related species from interbreeding is an example of ________.

The actions of humans are having negative impacts on the environment at a global scale. Of the options listed, which impact is an EXCEPTION to this trend?

The biological species concept cannot be applied to fossils. Which alternate approach to identifying species would be most useful for classifying fossil organisms?

Examine the evolutionary relationships represented in the accompanying figure. Based upon this model, which of the following pairs of organisms are most closely related?

Under the biological species concept, what criterion is used to assign populations of organisms to the same biological species?

Scientists who study evo-devo engage in research in the fields of ________.

Why is it INCORRECT to assume that mass extinctions carry only negative impact on the evolution of life on Earth?

Molecular systematics might examine all of the following types of data EXCEPT ________.

The current geological era is the ________.

Human migration and global trade are two factors that have altered geographic distribution of parasites. One result of this phenomenon is that humans are introduced to new infections more often, and they can be co-infected by several parasites from different species or lineages. These co-infections can result in matings between individual parasites of the different species and lineages. What biological diversity concept does this phenomenon provide evidence for?

Which scenario describes allopatric speciation?

Scenario In some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." Male ligers are sterile but some female ligers are fertile. In the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. Furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. -Applying the biological species concept, the sterility of ligers reveals that ________.

What type of reproductive isolating mechanism is described by a situation in which female fireflies mate only with males who emit light in a particular pattern?

The wing of a penguin is ________ the wing of a butterfly.

Homology is evidence of ________.

If a method of classification is used that compares similarity in shared ancestry, this method is using ________ as the basis of classification.
