Divergent speciation refers to the rise of a new species when organisms that can interbreed and reproduce fertile offspring get separated. Separation can be due to geographical barriers like mountains and lakes.

∙ 11y agoDivergence is both the cause and the result of speciation. Speciation marks the boundary between the level of divergence where interbreeding between subpopulations is still significant, and the level of divergence where it is not. When subpopulations of the same ancestral stock diverge, speciation may occur. When populations stemming from the same ancestral stock become and remain reproductively isolated (eg. when speciation has occurred), divergence may proceed unimpeded.

What is divergence in relation to evolution?
Increasing divergence between reproductively isolated populations, occasionally leading to speciation, is one effect of evolution.
Why is isolation important in evolution?
It is the reproductive isolation between populations that allows divergence between populations, and ultimately speciation, to occur. Often this reproductive isolation is the result of geographical isolation, for instance when part of a population migrates to new territories.
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.
Does the amount of chromosomes in a species affect its rate of evolution?
The "rate" of evolution is most accurately gauged in terms of divergence between genetic sequences. Chromosomes are basically groupings of such sequences. It is certainly possible that the number and order of these groupings affect future developments (for instance: polyploidy and chromosomal fusions can affect speciation events), but they do little to affect the overall "rate" of divergence.
What is the difference between macro evolution and micro evolution?
The difference is one of scale and scope. This is best explained using a single species and its descendants as an example:Every change that happens to the species up to the point of speciation would be classified as "micro-evolution". But after speciation, divergence would not stop: the two new species would continue to diverge from one another, possibly resulting in yet more branching events, more new species. The scope would increase to include all of those as well. At this scale, we're talking about "macro-evolution". When we zoom in on one of those newly emerged species, we can see that the resulting "macro-evolution" is still being generated by the cumulative effects of "micro-evolution" within each individual population.

Divergence may lead to what?
speciation
What is often a result of evolution?
Adaptation, divergence and speciation.
Difference between convergence and divergence?
Convergence- When things come together Divergence- When things move apart
How speciation takes place.?
because divergence leads to the formation of new species
What is the relationship between speciation and the theory of punctuated equilibrium?
No difference.
Does convergent evolution result in speciation?
All evolution that results in increasing genetic divergence between subpopulations may result in speciation. That includes convergent evolution: convergence occurs at the phenotypical level, not at the genetic level.
Why is isolation important in evolution?
It is the reproductive isolation between populations that allows divergence between populations, and ultimately speciation, to occur. Often this reproductive isolation is the result of geographical isolation, for instance when part of a population migrates to new territories.

What is the difference between curl and divergence?
Divergence: rate of spread of vector in free space for non closed path. and Curl: rate of spread of vector in free space for closed path.
What is phyletic speciation?
Divergence
If a population becomes isolate from other populations of the same species and then genetic divergence occurs that prevents them from breeding with other populations what is it called?
It is called speciation.
