Which of the following shows an example of organisms being classified based on their physiological abilities?
Speciation occurs during the evolutionary development, or phylogeny, of a species. In which of the following situations will speciation occur
What is believed to be the dominant mode of speciation among most groups of organisms?
The dominant mode of speciation among most groups of organisms is allopatric speciation. This occurs when populations of a species become geographically isolated from each other and over time, genetic and environmental differences accumulate, leading to the formation of distinct species.
What similar organisms do not interbreed because of a physical barrier?
Allopatric Speciation : NovaNet
Describes why similar organisms do not interbreed because of a physical barrier?
Allopatric Speciation
When one group of organisms gives rise to several other groups of organisms the original group is referred to as?
a common ancestor.
How do evolution and microevolution differ?
Miroevolution is the change in allele frequency overtime in populations of organisms not leading to speciation; below the taxa level. Macroevolution is speciation. This terminology is not favored by many biologists because there is some implied difference in processes. That is to get from micro to macro. Actually evolution long enough is macro. So, many biologist prefer the terms. Evolution Speciation instead of micro and macro

Speciation occurs during the evolutionary development, or phylogeny, of a species. In which of the following situations will speciation occur
Which form of speciation is most rapid A. sympatric speciation via character displacement B. allopatric speciation on the island archipelagos C. sympatric speciation via autopolyploidy D. allopa?
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.

Slow change over time in a species is a way to define?
It is called speciation. Speciation can happen through adaptation, which is a change in an organisms genetic code. If adaptation has gone on long enough so that the two organisms can no longer produce offspring, then speciation has occurred.
A new species that forms in only one generation is an example of .?
instantaneous speciation
