As a genetically homogeneous species, elephant seals have a diminished capacity to evolve in response to environmental changes that may occur in the future—the entire population will be affected, to about the same degree, by any adverse changes. Do you think that elephant seals, regardless of their abundance, should be considered potentially endangered for the foreseeable future? Why or why not?

Tests on wild cheetahs have shown that there is low genetic diversity among individuals. Wildlife biologists and conservationists are worried about what this means for the survival of this species. Why is low genetic variability a big problem when it comes to a species survival in a changing habitat?
Some 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?
SCIENCE, TECHNOLOGY, AND SOCIETY Consider how the adaptive value of sea turtle migration has changed if, as a result of human activities, migration now puts sea turtles at greater risk than if they restricted their habitat to a single location. Discuss the possible evolutionary mechanisms by which the behavior of these species may (or may not) adapt to these environmental pressures. What conservation efforts should we take to increase the probability of successful migration?
We (humans) do not have any ethical burden to worry about other species because extinction is a natural process. True or False?
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?
Two ecologists walk into a bar. After a few drinks, they begin to argue about which would be at greater risk of extinction: a population of 100 African elephants (Loxodonta africana) or a population of 100 house mice (Mus musculus). Provide the best argument you can in favor of each. Why elephants are at greater risk: Why mice are at greater risk:
The rough-skinned newt, which lives in western North America, stores a poison in its skin and is avoided by predators. However, several populations of garter snakes have undergone one or a few mutations that enablethem to tolerate the toxin, and these snakes eat the newts with no ill effects. How has natural selection affected this predator–prey relationship? Based on what you have learned about evolutionary arms races, predict what may happen to the newts and the poison-resistant garter snakes over time.
The Tibetans and Han Chinese share several genetic traits and DNA. However, the EPAS1 gene, which increases the ability of red blood cells to carry oxygen even in low oxygen environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is only common in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in three to five sentences
At the edge of the Arctic Circle, owls prey on field mice. Occasionally, in a litter of white field mice, a brown mouse appears. Because of greenhouse warming, the snow melts, changing the environment to shades of brown. What is most likely true regarding the brown mice before the greenhouse warming? The brown mice population was large in number. The brown mice population was small in number. The fur color of mice changed to white because they needed to survive. There were no brown mice born before greenhouse warming.
In one of the hypotheses that explain the extinction of the dinosaurs, the rapid climatic change produced an environmental situation with which these species could not cope. How important is the total amount of variation present in the population if the selective pressures suddenly change? Why?
Why should we take caution when public discussions promoting efforts that would result in reducing modern human variation occur?
