Re: More assertions from jar
hi ICANT, from reading your posts in this thread it appears that you accept that speciation has taken place:

I do believe that two population can become so different they can't interbreed as my horse avatar would be evidence of.
​
this fits the definition of the biological species concept, so no problems there.

as you are using the definition of 'macro evolution' from the op:

I want to vary specific here, when I say Macro-Evolution I am speaking only of a scale of analysis of evolution in separated gene pools. Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution, which refers to smaller evolutionary changes (typically described as changes in allele frequencies) within a species or population. {Quoted from Wikipedia.org}
​
Just so we are on the same page when writing our posts, I am using the definition of 'Macro-Evolution' as presented in the OP.
​
it would seem as though you accept at least one instance of macro evolution.

definition of 'macro evolution'
hi again ICANT, and thank you for the welcome.

Were they both hogs? Yes.
​
Are they classified as different species? Yes, go figure.
​
To me they are just a different variety of the same thing.
​
cool, we agree that new species can come into existence.
​
it seems that we only differ in our interpretation of the definition provided in the op.

​
now to me, a change that occurs 'at the level of species' would be an instance of speciation, but you don't seem to share that view. could you expand on what you think a change 'at the level of species' would be?

(eta: by the way, i know you're heavily outnumbered in this thread, so no rush)
