The definition of speciation is: "The formation of new and distinct species in the course of evolution."
speciation - definition of speciation in English | Oxford Dictionaries Either you deny speciation or you deny evolution. Which is it?
I do not deny speciation. I deny it results in a new species. The extensive study of salamanders in California never called them a different species. The called them a sub-species.
A subspecies is not a different species. If 2 breeds of dogs mate, their offspring will be a subspecies of the parents, but it will still be a dog.
Another problem: The subspecies was determined by their inability to breed. Of the thousands of salamanders in each sub species, they could not possibly have a large enough sample to say with certainty none of them were breeding.
Here are some comments from the ICR: "If different species are described as essentially those forms which cannot interbreed, then new species do arise, a process called "speciation." They do so, however, because of a loss of information--the opposite direction to what Darwinian evolution requires. For example, "the 'herring gulls,' as you move around the globe, become…more like lesser black-backed gulls."5 They interbreed in a continuum, until the ends of the ring meet in Europe, where these two species no longer interbreed. These changes are presented as evidence for evolution, but really only represent variety within the gull kind. And "it is by no means certain that this type of gradual process can lead to the origin of a fundamentally different species."
