What is a increasing biodiversity?
Speciation and extinction increase biodiversity.
Biodiversity is believed to be the result of?
There is a great deal of diversity in living organisms. They are generally broken down into plants and animals, as well as animals with backbones and without.
How are species related to the concept of biodiversity?
Species are finite categories in which individual fauna fall into. They are typically characterized by an inability to interbreed with other species and create viable offspring. While a horse and a donkey can create a mule, the mule is in almost all cases sterile and thereby not a viable offspring. Biodiversity is created by having many different species. Speciation (the process in which new species come to exist) is responsible for creating biodiversity.
Why does polyploidy not cause speciation or even be associated with speciation?
Actually it is.
Speciation without geographic isolation is called what?
Sympatric Speciation develops within the range of the parent population. This type of speciation does not include geographical isolation, and can occur rapidly if a genetic change results in a barrier between the mutants and the parent population.
Which form of natural selection is most likely to play a role in speciation?
Disruptive Selection
How does speciation process affect evolution?
Speciation adds to biodiversity. Hence it affect the evolution of best suited forms to come up.
What is an effect of adaptive radiation?
speciation
What do directional selection and disruptive selection have in common-?
directional selection and disruptive selection both decrease genetic variation - apex
How does disruptive selection lead to sympatric separation?
According to Wikipedia: "Disruptive selection describes changes in population genetics in which extreme values for a trait are favored.It is believed that disruptive selection is one of the main forces that drive sympatric speciation in natural populations.Sympatric speciation events are vastly more common in plants.A rare example of sympatric speciation in animals is the divergence of "resident" and "transient" Orca forms in the northeast Pacific.Resident and transient orcas inhabit the same waters, but avoid each other and do not interbreed. The two forms hunt different prey species and have different diets, vocal behaviour, and social structures."

Is there evolution in modern man?
Evolution, the change in allele frequency over time in a population of organisms, always goes on. Speciation, on the other hand, does not seem to be happening in man, but there is some controversy there. Stabilizing selection is possibly what humans are being subjected to.
Speciation caused by change in the course of a river is an example pf divergent speciation?
Allopatric speciation.

Types of Speciation?
sympatric , allopatric and parapatric speciation
What is necessary for speciation to occur?
Isolation Is necessary for speciation to occur.
