Question
Chapter 52, Problem 15TYK
Summary Introduction
To review:
Develop an evolutionary hypothesis for many animals, including humans and other primates, live long beyond their reproductive years. Design a study that might test it.
Introduction:
The females of some species especially primates cease reproductive years before the end of their natural lifespan is a venerable evolutionary puzzle. Natural populations of humans as well as some cetaceans and insects exhibit reproductive senescence earlier than somatic aging and females exhibit expanded post-reproductive lifespans (PRLSs).

Consider that you are a civilian resident living on the Chatham Island in New Zealand where a long-finned pilot whale stranding event with 100 beached whales is happening and maybe have even been participating in the response to the strandings. Raise specific questions that you may have for the local government or researchers about the stranding. Argue for an alternate hypothesis as to why the event occurred. Use and fully cite in-text peer-reviewed journals and government organizations, to support all data. Then, provide a full reference section at the end to list all the sources used
A skeptic of evolution asks the following question – “If humans evolved from monkeys, why are there still monkeys?” Use your understanding of primate evolution to explain to this individual why their view of primate evolution is skewed. Reference examples.

- Members of some species will sound warning calls when they notice predators even though this increases the likelihood the predator will find the individual that provided the alarm. The evolution of such behaviors provides evidence for which hypothesis? A. Evolution selects behaviors that increase the ability of individuals in a species to camouflage. B. Evolution selects behaviors that increase the likelihood that individuals in a species will reproduce. C. Evolution selects behaviors that increase the the likelihood that individuals in a species that share similar genes will survive and reproduce. D. Evolution selects behaviors that increase the likelihood that individuals in a species that share similar genes will migrate.arrow_forwardConsider the concept of evolution.

A student in a course on intelligent design theory claims that the graph in part (a) shows that losing the ability to respire actually is adaptive for yeast cells living in small populations. Please read the incomplete sentence that appears immediately below, assess as possible completions the lowercase-Roman-numeral-labelled statements that follow, and click each uppercase-letter-labelled response that is presented below and completes accurately the sentence. An astute student in an evolution course would respond that i. the graph in part (a) shows that selection among mitochondria within yeast cells can lead to fixation for traits that decrease mean fitness for that yeast population. ii. the student in the course on intelligent design is wrong; the yeast cells in the small population group retained completely the ability to respire, as they otherwise would have been unable to harvest energy. iii. a property (e.g., inability to respire) that is…arrow_forwardWrite an explanation for how the process of evolution primarily results from competition for limited resources (such as water, shelter and mates) and differences in the abilities of individuals in a population to survive and reproduce in that environment.arrow_forward

The offspring resemble their parents (i.e. they look like lizards from their home island). Does this support or contradict the idea that evolution has occurred? Group of answer choices a. support because it implies that a genetic change has occurred b. contradict because the lizards were removed from the islands c. support because the phenotype matches the environment d. contradict because the environment is different in the lab e. support because it is a major change in phenotypearrow_forwardWhich sequence of events in human evolution is most widely accepted?
