This is speciation that scientists have directly observed, genetically confirmed, and can still see in nature today.
The claim begs for a precise definition of "species".
That's one of the many huge problems for creationism. If creationism were true, there would be nice definable separations between species. But instead, as Darwin predicted, we see all sorts of intermediate cases. Reproductive isolation defines species. But even that isn't perfect. In the case of clines or ring species, the extinction of a part of the population could retroactively make microevolution into macroevolution. Would you like to learn how?
Hybrids are microevolution events.
Usually. But sometimes, it results in a reproductively-isolated species. Would you like to learn about how that works?
Scientists have directly observed macroevolution. Even many YE creationists admit the evolution of new species, genera, and sometimes families. They just moved the goal posts farther out to change the definition of macroevolution.
So you have not observed a speciation event but now claim others have.
I haven't observed a volcanic eruption either. But I'm pretty sure they are a fact. Just like macroevolution.
Words mean things. If you don't use them as others do, you're never going to communicate effectively.
BTW, all definitions are tautologies, a phrase or expression in which the same thing is said twice in different words.
And of course, it's instructive. I just showed you what the word means.
But words that tell us nothing new are meaningless tautologies.
In this case, "macroevolution" is defined as speciation. So, it points out that evolution not resulting in reproductive isolation is not macroevolution. Which seems like an important concept to me. But then, I've spent a lifetime studying biology. So your take might be different.
For example, "All triangles have three sides."
Kinda like "all macroevolutionary events involve speciation." Your example strikes me as informative. Math teachers would think so. But then, they've spent years studying math.
Contrast it with the statement, "No triangle has any diagonals," which not a tautology.
Contrast it with the statement "No macroevolutionary event happen without speciation." Which is not a tautology.
I don't think you've given this matter enough thought.
