What affect do humans have on speciation?
As part of the environment of other organisms humans can have great effects on speciation. Especially adaptive radiation. As we contribute heavily to the extinction of some species other species flow into those open niches and radiate outwards to possible speciation.
Darwin's finches speciation how did the population separate?
The distance between the islands meant that the Fincehes on different Islands could not interbreed wich led to some extinction
Which type of evolution requires speciation?
Speciation is the evolutionary process by which new biological species arise.
What effect would a very short generation time such as bacteria have on speciation?
Well they would evolve faster, so speciation would occur faster too
What is a Anagenesis?
Speciation without branching of the evolutionary line of descent.
What happens if the rate of extinction in a clade is greater than the rate of speciation?
Do your own hw
What term describe development of new species and mass extinction?
Macroevolution The development of a new species is called speciation.
Which term best describes the result of a new species evolving from an existing species?
Extinction

What is the relationship between environmental change speciation mass extinction?
Environmental changes can stimulate speciation by creating new opportunities for organisms to evolve and adapt to new conditions. However, rapid and extreme environmental changes, such as those associated with mass extinctions, can lead to widespread species loss and disruption of ecosystems, accelerating the extinction rates.
What is the process that keeps the number of total species on Earth from growing exponentially through speciation?
Speciation is the evolutionary process by which new biological species arise. The biologist Orator F. Cook seems to have been the first to coin the term 'speciation' for the splitting of lineages. Whether genetic drift is a minor or major contributor to speciation is the subject matter of much ongoing discussion. The process of speciation is often hastened when two formerly isolated groups are reunited.

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 are the two factors that account for diversity of species?
The diversity of sexually reproducing species is a result of the fact that a) gene pools change over time (by selection and genetic drift) and that b) reproductive isolation occurs, leading to the inability of the descendants of formerly interbreeding subpopulations to interbreed (speciation).
Complete reproduction isolation is evidence that what has occurred?
speciation
What is necessary for speciation to occur?
Isolation Is necessary for speciation to occur.
