Question
Chapter 56.3, Problem 2SB
Summary Introduction
To review:
The selection pressure that fosters seasonal migration in birds.
Introduction:
There are some birds which migrate to a distant location to complete a phase of their life cycle in those regions. It mostly occur to increases the survival chances in a distant location than at the birthplace.

What is the primary physical feature in which the species of finches differ?
In birds of paradise that populate tropical rainforest ecosystems, bright colored beaks and feathers are commonly found. These phenotypes continue to persist, even though brightly colored birds are more easily seen by predators. Which of the following would best describe the reason behind the persistence of these phenotypes in birds of paradise?
What behavioral trait(s) prevents interbreeding between different finch species?

- Explain Measuring the heritability of bill depth in populations of Darwin’s finches?arrow_forwardPeter Boag, studied the inheritance of beak depth in Galapagos finches by looking at the relationship between parent beak depth (in mm) and that of their offspring. He collected two sets of parent offspring data, once in 1976 and again in 1978. For both years he followed birds to determine which pairs belonged to which nests. Most of the parents had been previously captured so their beak depths were known. He then captured the offspring when they fledged and measured their beak depth. He calculated the "midparent" beak depth (the average beak depth of the two parents) and then compared that to beak depth of their offspring. Here is what he found in 1976: Assume that in 1978, all the finches with beak depths less than 9.0 mm died due to prolonged drought. Use your knowledge of how quantitative traits respond to selection and the following relationship, R = h2S, to determine the following: Selection differential.

- How do mechanisms of speciation, such as genetic isolation, reproductive barriers, and ecological factors, apply to the human-chimp-gorilla trichotomy? Discuss the role of these mechanisms in driving speciation and shaping the evolutionary relationships among humans, chimps, and gorillas, based on genetic evidence such as comparative genomics and molecular phylogenetics.arrow_forwardIn the eclectus parrot (Eclectus roratus), mothers sometimes take parental favoritism to extreme lengths by killing their sons, but never their daughters (Heinsohn et al. 2011). Sex-specific infanticide occurs more often at nests that can be flooded during the rainy season. Sons spend longer in the nest than daughters. Link this factor to why it might be adaptive for a parent parrot to kill a son in a vulnerable nest occupied by offspring of both sexes.
