This was your quote:Freddy:
It was a concession in definition I made to @rossum. He wanted to define speciation as macro. I disagreed and redefined it as essentially long term lineage splitting leaving organism less fit and on the path to extinction. If he was OK with it I said OOOOOOOKKKKKKKK.The problem that you might have noticed is that some on this thread deny that ‘macroeveolution’ occurs. Now I don’t know about you but if we have one species evolved from another and they can’t interbreed then it’s pretty much an example of ‘macroevolution’. Yet some (Buffalo) would argue that not being able to interbreed with the original species is an example of how evolution works in a negative sense.
So on one hand he says it doesn’t happen and on the other says that when it does happen it proves evolution works in a negative way. Such is the tortuous logic with which we have to wrestle.
‘Macroevolution, the lineage splitting with loss, of a new species, has been observed. It is an established fact; no assumption required’.
One of your claims is that the fact that a new species cannot interbreed with the ‘parent’ species (and that is a loss). We can, with certain exceptions, accept that one of the definitions of species is precisely that. That is, it cannot interbreed with another species.
Hence a new species that cannot interbreed with the original species by your own definition (see above) is macroevolution.
So your own definition defines something you claim is part of the process (new species losing the ability to interbreed) but which you constantly claim does not exist.
I’ve said this many time but I’ll say it again. Truly bizarre…
