Chapter 57, Problem 14TYU
Summary Introduction
To determine: The reason why the declining biological diversity is a threat.
Introduction: Biodiversity (biological diversity) is the difference among the organisms. From the population to the ecosystem, biodiversity takes place in all level of ecological organizations. The management of nature and biodiversity from the excessive rate of extinction and erosion of biotic interactions is called conservation biology.

Once a mutualistic relationship evolves between two species, will natural selection and co-evolution cause the two species to become continuously more dependent on each other? Or is it possible for one to end the mutualism? Describe.
One way to prevent a small population of a plant or animal species from going extinct is to deliberately introduce some individuals from a large population of the same species into the smaller population. In terms of the evolutionary mechanisms discussed in this chapter, what are the potential benefits and drawbacks of transferring individuals from one population to another? Do you think biologists and concerned citizens should take such actions?
Throughout Earth’s history, many species, and perhaps even most of the species that ever existed, have become extinct. The causes are numerous: climate change, volcanic activity, the actions of oxygen-producing organisms, changes in carbon dioxide concentration, and even asteroid impacts. Have humans ever caused extinctions?

- Because new species will eventually evolve to replace those that humans are driving to extinction, why is declining biological diversity such a threat?arrow_forwardWhich of the following terms most specifically describes what occurs when a group of organisms expands to take on new ecological roles, forming new species and higher taxonomic groups in the process? (a) speciation (b) mass extinction (c) evolution (d) adaptive radiationarrow_forwardWhich of the following statements about extinction is not correct? (a) extinction is the permanent loss of a species (b) extinction is a natural biological process (c) once a species is extinct, it never reappears (d) human activities have little impact on extinctions (e) thousands of plant and animal species are currently threatened with extinctionarrow_forward
- How does an individual with a competitive advantage lead to the evolution of an entire species? Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland. Traits that are advantageous help certain individuals reproduce at higher rates, so those traits are more common within the population. Some individuals are better at competing for resources, and that allows them to survive droughts or other major ecological events, leading to the extinction of certain species and the survival of others. Those who have traits that help them survive are able to reproduce, and their offspring have those traits, leading to a change in the species over time.arrow_forwardIf a sixth extinction event is occurring, how is it similar or different from the previous five mass extinctions? What sort of evidence do you think scientists look for to determine whether we are living through a mass extinction?arrow_forwardDistinguish between biological extinction and mass extinction. Does every species have the right to survive without human interference, regardless of whether they serve a useful purpose to humans? Explain?arrow_forward
- In the early nineteenth century, the French scientist Georges Cuvier provided conclusive evidence of the extinction of species on Earth. Although Cuvier correctly asserted that a series of catastrophes led to these extinctions, he could not provide a testable explanation of the source of the new animals and plants that appeared after the extinction of older forms. How would you argue that modern evolutionary theory provides an explanation for the proliferation of new forms of life after mass extinctions?arrow_forwardSince different species may occupy the same habitat, explain why they continue to remain separate species? Adaptive 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. What types of biological evidence would you need to look at to determine evolutionary relatedness between penguin species? **ALL ANSWERS ARE ABOUT THE SPECIES OF PENGUINS**arrow_forwardBecause mass extinction is a natural process that may facilitate evolution during the period of thousands to millions of years that follow it, should humans be concerned about the current mass extinction we are causing? Why or why not?arrow_forward
- The mechanisms of evolution that we have learned contributed to the diversity of organisms we have today. We can see these organisms everywhere, even not physically but we learned about them on TV, books, social media, and others. We come to appreciate them and be amazed by their structures, mechanisms of eating, survival and many more. We also learned that we, humans, can be a contributory factor on lessening their diversity potentials and even their survival through hunting, destroying and relocating their habitats. As a member of the community you are living in now and with the remaining diversity of organisms present in your place, identify organisms you think are nearing extinction/endangered or have low diversity. Afterwards, write the reasons for this if you know, or possible reasons if not. Lastly, present a plan on how the community can work together in preserving and encouraging more variation in these organisms in the near future. You can ask help from the elders for their…arrow_forwardIn 1847, the German biologist Christian Bergmann noted that mammals and birds living at higher latitudes (farther from the equator) are on average larger and bulkier than related species found at lower latitudes. Suggest an evolutionary hypothesis to explain this observation.arrow_forwardAdaptive radiations can be a direct consequence of three of thefollowing four factors. Select the exception.(A) vacant ecological niches(B) genetic drift(C) colonization of an isolated region that contains suitablehabitat and few competitor species(D) evolutionary innovationarrow_forward
