Do not confuse the fact that something is more complicated than you had imagined, sufficiently so as to require some statistical math, with its non-existence." -donh-
Eating back your own words, eh?
In post 307 you said:
"no one knows what the precise moment of speciation is" My statement therefore stands in spite of your attempt at confusing the issue.
...by asking you to learn some rudimentary notions about stochastics? Speciation is probablistic in nature. Some examples of a "species" may be able to procreate successfully with some other examples of another "species", while most such attempts would fail. This is the nature of stochastic behavior. You can describe the relationship of the chances of successful procreation as a bell curve. And no one's drawn an arbitrary line in the sand and said "x much probability of successful procreation means speciation". This is why speciation is inexact. Kindly make at least an attempt to follow along in the text. You are far too easily confused to be making the assumption that I am the source of it so readily.
