Two species of fish had recently undergone sympatric speciation. The males of each species had a different coloring through which females could identify and choose a partner from her own species. After some time, pollution made the lake so cloudy it was hard for females to distinguish colors. What might take place in this situation?
The process in which environmental pressures result in the differential survival and reproduction of individuals of a population is called _________. a. catastrophism b. evolution c. natural selection d. genetics
House sparrows (Maya) were introduced to North America in 1852. Since that time thesparrows have evolved different characteristics in different locations. Sparrow populations inthe north are larger-bodied than sparrow populations in the south. This divergence inpopulations is probably at least partly a result of natural selection: larger-bodied birds canoften survive lower temperatures than smaller-bodied birds can. Colder weather in the northmay select for larger-bodied birds. What type of evolution based on natural selectionaccounts for this observation? Explain your answer.
The elaborate tail of the peacock (Pavo cristatus) is approximately 120 cm to 150 cm long, while the tail ofthe peahen is quite short. The long tail reduces the male bird’s ability to maneuver and fly and makes him moreconspicuous to predators. Suggest at least one reason why this cumbersome structure has not been eliminatedby natural selection.

Which of the following is a factor that, by itself, does not promotewidespread changes in allele or genotype frequencies?a. New mutationb. Natural selectionc. Genetic driftd. Migratione. Nonrandom mating
. Some scientists vigorously rejected Darwin’sideas when On the Origin of Species was published. Richard Owen (1860), perhaps the mostrespected biologist in England, wrote (amongmany other objections): “Are all the recognisedorganic forms of the present date, so differentiated, so complex, so superior to conceivableprimordial simplicity of form and structure,as to testify to the effects of Natural Selectioncontinuously operating through untold time?Unquestionably not. The most numerous livingbeings … are precisely those which offer suchsimplicity of form and structure, as best agrees…with that ideal prototype from which…vegetableand animal life might have diverged.” Howmight Darwin, or you, argue against Owen’slogic?
Lithobates clamitus. also know as the green frog and bronze frog can range in in skin color from pure to brown to pure green and a mixture of both. As their habitats change frogs with a mixture of both colors have a higher fitness as they are better able to hide from predators. 1. If the change in the distribution of this trait is the result of natural selection, name the mode of selection (ie: Balancing, Disruptive, etc...) 2. If a small group of male frogs end up joining this population from a different population of frogs, which process of selection describes the movement of alleles present in the male frog? 3. The process you named in “c” ________ the genetic variation in the population that the male frog joined? (increase, decrease, or stay the same?)
The difference between sympatric and parapatric speciation is ___. a. parapatric speciation occurs only in worms b. sympatric speciation requires a barrier to gene flow c. the extent of overlap in range d. reproductive isolation does not occur
