Document Summary

Study guide for comprehensive portion of the final exam. Chapter 23: explain the statement it is the population, not the individual that evolves. , natural selection acts on individuals, but the evolutionary impact of natural selection is only apparent in the changes in a population of organisms. List the five conditions that must be met for a population to remain in hardy- Chapter 24: distinguish between allopatric and sympatric speciation, allopatric speciation- gene flow is interrupted when a population is divided into geographically isolated subpopulations, sympatric speciation- occurs in populations that live in the same geographic area. List the reproductive barriers that may lead to speciation and identify whether they are a prezygotic or postzygotic barrier. Gametic isolation (sperm cannot fertilize egg: postzygotic: Chapter 25: explain the endosymbiotic theory for the evolution of the eukaryotic cell (see. Figure 25. 9: mitochondria and plastids (chloroplasts and related organelles) were formerly small prokaryotes that began living within larger cells.

a) Traits must be inherited

b) Traits must influence reproductive success

c) Inherited traits must have variation within the population

Charles Darwin...

Describe the theory of natural selection Which of thefollowing BEST describes the theory of natural selection? CHOOSEONE

	1 The genetic make-up of apopulation gradually changes from one generation to the next.
	2 Living organisms change overtime.
	3 Each species produces many moreoffspring than can survive long enough to reproduce. The offspringthat do survive contain genes that are inherited from theparents.
	4 There is variation among themembers of a species. Some of this variation is geneticallydetermined and so can be passed on to future generations.
	5 Some individuals have genes thatincrease their chances for survival and reproduction. Theseindividuals are more likely to reproduce and pass on their genes,causing their genes to become more common in the nextgeneration.
	6 There is a struggle for existenceamong the members of a population.

1. Traits don't necessarily have to be passed on from parent to offspring for natural selection to act on them; traits that are environmentally acquired during the life time of an individual (such as practicing to become very strong or very fast) can also be acted upon by natural selection. Select one: True or False

2.Within the same species and even within the same population, not all individuals are the same. They vary in size, shape or other traits.

Select one:

True

False

3.Differential reproductive success means that some individuals in a population leave more offspring that survive and reproduce relative to other individuals in a population.

Select one:

True

False
