B. Allopactric speciation on island archipelagos. As the organisms move from island to island rapid speciation is observed because of variations in resource acquisition more than just variation in environment. Amplified radiation is observed. Example is finches on the Galapagos Islands. Hawaii also gives this example.

Speciation caused by change in the course of a river is an example pf divergent speciation?
Allopatric speciation.
What kind of selection can result in speciation?
Natural selection seems to be the only selection that can drive speciation with powerful adaptive change. Sexual selection seems to stay within the species and both gene flow and genetic drift do not seem to drive speciation very well.
How can islation lead to formation of new species?
Allopatric Speciation (geographic isolation) can lead to the formation of a new species because the population is split in two smaller populations by a physical barrier (river, canyon, mountain...).
How do Darwin's finches exemplify speciation?
Darwin was puzzled about the many adaptations of the finches on the Galapagos Islands
What type of speciation requires a geographic barrier?
Alopatric speciation. " Other country. "
Types of Speciation?
sympatric , allopatric and parapatric speciation
Autopolyploidy is a speciation process that begins with an event during?
Meiosis
The emergence of new species when a population becomes geographically isolated is termed what?
This concept is called allopactric speciation.
Compare and contrast allopatric and sympatric speication?
Allopatric and sympatric speciation are both methods by which new species arise. However, allopatric speciation is when species interbreed. Sympatric speciation is when several new species arise from a common ancestor.
Speciation caused by change in the course of a river is an example pf divergent speciation?

Allopatric speciation requires?
geographic isolation.
Which type of speciation occurred among galapagos islands finches?
