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.

- EVOLUTION LINK Charles Darwin once said, It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change. Explain what he meant.arrow_forwardSome scientists believe we are in the midst of a new phase of mass extinction, influenced by human behavior, threatening the earth’s biological diversity and contributing to widespread ecological crises. How can the study of non-human species help shape human responses to these potential threats?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
- EVOLUTION CONNECTION Describe how gene flow, geneticdrift, and natural selection all can influence macroevolution.arrow_forwardEVOLUTION LINK. In what ways does evolution depend on transfer of information? In what ways does transfer of information depend on evolution?arrow_forwardWe (humans) do not have any ethical burden to worry about other species because extinction is a natural process. True or False?arrow_forward
- The proliferation of the Homo sapiens species has been attributed by scientists to their migration around the African and Eurasian continents between 70,000 and 100,000 years ago. What enabled this constant migration? What resulted from this constant migration?arrow_forwardOnce 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.arrow_forwardPerhaps 98 percent to 99 percent of all species that have ever existed areextinct. Nearly all went extinct long before humans arrived on the scene. Whyshould we be concerned about the extinction of organisms today?arrow_forward
- Climate warming could lead to all-female populations of bearded dragons, resulting in extinction of the species. What are some other potential effects of climate warming on natural populations of organisms?arrow_forwardWhat three processes characterize many major transitions? Would you consider mammals such as cetaceans (whales & dolphins) moving from terrestrial to aquatic habitats as a major transition? Explainarrow_forwardMany species of animals make alarm calls, which warn others in their group that a predator is approaching. Alarm calls also attract the atten- tion of the predator, making it more likely that the individual making the call will be eaten. Why might natural selection favor the evolution of alarm calls in a species? How might you test that hypothesis?arrow_forward
