What are three ways that can lead to speciation?
by natural selection, genetic drift and geographical isolation
Does evolution always involve speciation?
No, speciation is not a logically necessary consequenceof natural selection. However, given that circumstances can and inevitably will lead to divergence between sub-populations of a species, speciation can be said to be a practically inevitable consequence of evolution. It's a bit like balancing a sharp pencil on its point. Theoretically it can be done. In practice, however, the pencil will fall over the second you let it go.
Polyploid speciation is perhaps the fastest form of speciation because it results in immediate?
reproductive isolation
What type of selection can create 2 new species from one population?
There are several types of selections that can do this. It includes allopatric speciation where the population is separated by physical barrios, sympatric speciation where variations occur in the population, and allopolyploid when two species merge.
What is speciation ?
the formation of species
Divergence may lead to what?
speciation
What are three events that lead to speciation?
Separation, Adaptation, Division
Natural selection can lead to the formation of a new species which is called?
The development of a new species through evolution is called speciation.
What is thought to be the two factors demonstrating sympatric speciation in the cichlids of Lake Victoria in East Africa?
-rapid speciation -sexual selection
What are three factors lead to speciation?
Genetic drift. MutationsNatural selection.Gene recombinationGene flow (immigration and emigration)
What are the types of isolation the can lead to speciation?
reproductive, behavioral, geographic, and temporal
Natural selection is the only mechanism of evolution that will lead to?
Adaptive change and speciation.
Speciation is the process by which new species are formed Which of the following circumstances is most likely to lead to speciation?
A population becomes separated by different environments and do not reproduce with one another.
What are three ways that can lead to speciation?
by natural selection, genetic drift and geographical isolation
What are three events that can lead to speciation?
Species (phylogenetically and genetically distinct animals from a common ancestor) form when barriers exist to prevent outbreeding. These are usually environmental (e.g. mountain ranges, oceans, climatic barriers) or biological (e.g. interbreeding of two species results in an infertile offspring).
What event could lead to speciation according to the punctuated equilibrium theory?
A meteor strikes Earth.
How do habitat and competition lead to speciation of Pollenpeepers on Warwick Archipelago?
how is natural selection occurring in the pollenpeepers
