1.
An earthquake and tsunami, Richter scale of 7, destroyed a small village near the epicenter in Indonesia. Families were separated, food became scarce and the land was too damaged for traveling between now divided landmasses. This situation prevails for an extended time period. Which of these speciation models more than likely will occur under these conditions?
a.
Sympatric
b.
Allopatric
c.
Peripatric
d.
Parapatric
e.
None of the above
2.

a.
It demonstrates that dominant alleles are more common than recessive alleles.
b.
It demonstrates evolution.
c.
It demonstrates that a locus can have only one of two alleles.
d.
It demonstrates that in the absence of outside forces, allele frequencies of a population will not change from one generation to the next.
e.
It demonstrates that heterozygotes are always better.

- Indicate whether each of the following conditions would tend to cause speciation to occur faster (F), or if it would tend to slow down or prevent speciation (S). Put either an F or an S in each box. A. a small sub-group of a population becomes geographically isolated from the main population and experiences new environmental conditions B. a large population of herbivores lives in an environmental where the conditions have remained stable over a long period of time C. a colony of monkeys clinging to floating debris is washed out to sea by a storm and lands on an island with diverse habitats, abundant food, but without any other primates D. a large population of a migratory species splits up every year and takes different routes to their common mating territoryarrow_forwardClimate change and glacial advances during the Pleistocene ice age (2.6 million to 11,700 years ago) split the ranges of several North American bird species into western and eastern populations. The western and eastern populations eventually diverged into two species. What is this an example of? A. Allopatric speciation following dispersal B. Allopatric speciation via vicariance C. Sympatric speciation due to balancing selection D. Sympatric speciation via autopolyploidy E. Sympatric speciation via allopolyploidyarrow_forwardWhich of the following is not an event that can contribute to allopatric speciation? a. A mountain range forms and splits two populations into populations that begin to turn into new species. b. A subset of individuals disperse to a far away island and begin to turn into a new species. c. Two populations breed in the same location but at different times, and therefore begin to turn into two new species. d. A river splits a population into two populations and the two populations begin to diverge on either side of the river. e. All of these are potential contributors to allopatric speciation.arrow_forward
