- 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 usedarrow_forwardMatch the following examples with the type of natural selection they are describing: .A Stabilizing selection B. Disruptive selection C. Directional selection Natural selection selecting against very high and very low testosterone levels in a population, leading to relatively stable testosterone levels over time A finch species arriving to an island with only insects and large seeds, with natural selection favoring very thin and very thick beaks, but not medium beaks. A population of bacteria evolving to have an increasingly higher resistance against antibiotics A rodent population evolving to a progressively smaller size to enable better thermoregulationarrow_forwardPesticides can be used to control a variety of pests, such as insects, weeds, rodents, bacteria, fungi, etc. Over time many pesticides have gradually lost their effectiveness because pests have developed resistance – a significant decrease in sensitivity to a pesticide, which reduces the field performance of these pesticides. 1. Why do pesticides lose their effectiveness over time? Use the theory of natural selection and evolution to explain.arrow_forward
- Explore how a Bengal tiger will adapt using artificial selection, natural selection, traits, alleles, fitness, selective pressures, mutationsarrow_forwardWhen discussing natural selection and behaviour, we often say that members of a species have certain behavioural traits because those traits are adaptive, in the sense that they increase inclusive fitness relative to alternative forms of those traits that have existed in the past. Instead of emphasizing the adaptiveness of behavioural traits, some biologists describe natural selection as a process that operates on nervous system traits, increasing the prevalence within a population of particular patterns of neural circuitry and neurobiological mechanisms. As an alternative to emphasizing either the behaviour or the nervous system, some biologists describe natural selection as a process that operates on genes; according to this perspective, certain forms of certain genes (ie., particular alleles) increase in prevalence within a population relative to alternative forms of those genes. Which, if any, of these three perspectives on natural selection and behaviour do you think is the most…arrow_forwardWhich of the following are not agents of natural selection? Select one: A. Neutral interaction with another species B. Competition among individuals for food and water C. Competition among members of a population for prime nesting sites D.
