A famous study from the nineteenth century involves the peppered moth,
Biston betularia, commonly found in Great Britain and Ireland. At that time, the
moths, normally white with black speckles, known as the
peppered variety, became less common than the solid black variety. The
population was predominantly black throughout the nineteenth century. By the
end of the twentieth century, the peppered version of the moth was again more
common than the black version.
Which of the following best explains the phenotypic pattern in the moths over
time?
The increased air pollution of the nineteenth century due to the use of coal led
to a darkening of surfaces from soot. The darker backgrounds conferred a
selective advantage to the black variety, as described by natural selection. A
shift to less polluting fuel in the twentieth led to
cleaner air and a lightening of the moth's normal habitat.
,2009 Phylogeny is the evolutionary history of a species.
(a) The evolution of a species is dependent on changes in the
genome of the species. Identify TWO mechanisms of genetic change,
and explain how each affects genetic variation.
(c) Describe TWO types of evidence—other than the comparison of
proteins—that can be used to determine the phylogeny of organisms.
Discuss one strength of each type of evidence you described.
Changes in DNA-mutations via insertions/deletions of dna
sequences/codons; therefore changes phenotype in some way (Most
mutations are unnoticable; others are lethal; few are advantageous)
Changes in population-allopatric=diverge due to enviro; symm=new
species evolve from common ancestor even though in same
geographic region; producing reproductive fitness
, The degrees of relatedness in several native populations of prairie
chickens in Marion and Jasper Counties in Illinois were determined. The
degree of relatedness is inversely proportional to genetic diversity; that
is, populations with a high degree of relatedness have less genetic
diversity. Table 1 shows the collected data. Populations J1 through J5 are
located in Jasper County. Populations M1 through M5 are located in
Marion County. Numbers above 0.125 indicate a high degree of
relatedness.
Table 1. RELATEDNESS OF PRAIRIE CHICKEN POPULATIONS
Population Degree of Relatedness
J1 0.215
J2 0.215
J3 0.339
J4 0.280
J5 0.362
M1 0.305
M2 0.365
M3 0.199
M4 0.432
M5 0.405
Scientists claim that some of the populations in Marion County are at an
increased risk of decline or extinction. Based on the data in table 1,
which of the following best provides evidence to support this claim?
The M4 and M5 populations have the lowest genetic diversity of all
populations.
