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).

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 event could lead to speciation according to the punctuated equilibrium theory?
A meteor strikes Earth.
Speciation caused by change in the course of a river is an example pf divergent speciation?
Allopatric speciation.
What are the two main types of isolation?
That would be geographic isolation and reproductive isolation. Both could lead to speciation.
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...).
What are three events that lead to speciation?
Separation, Adaptation, Division
What are three ways that can lead to speciation?
by natural selection, genetic drift and geographical isolation
Divergence may lead to what?
speciation
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 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.
What are 3 events that can lead up to speciation?
Isolation often leads to speciation, because as each isolated population evolves new characteristics, the separate populations eventually get DNA that is too different for the two to breed and have fertile offspring (this is the point when speciation has occurred). In the case that there is not isolation, the whole species must slowly evolve until it becomes a new species. However, here the line between where the speciation actually occurred becomes blurry, because it doesn't happen in a single generation.
What are three factors lead to speciation?
Genetic drift. MutationsNatural selection.Gene recombinationGene flow (immigration and emigration)
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 three apostles did Jesus choose to lead special events?
Peter, James, and John were the three apostles chosen by Jesus to lead special events such as the Transfiguration and the raising of Jairus' daughter.
What event could lead to speciation according to the punctuated equilibrium theory?
A meteor strikes Earth.
