- Sexual and Ecological selection often oppose each other: give 2 examplesarrow_forwardConsider this example. On a tropical island, there are iguanas that are green, blue, and yellow. The green iguanas can camouflage in the green grass, the yellow iguanas can camouflage in the dry, yellow grass. And the blue iguanas try to run fast to get away from prey. Over time, the blue iguanas disappear on the island, while the green and yellow iguanas survive. What type of natural selection is this? A. Balancing or Stabilizing selection B. Disruptive or Diversifying selection C. Directional selection D. Sexual selectionarrow_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_forward
