>>Joe, I think we need to define some terms. When I talked with you and Frank in a previous thread I think we may have misunderstood each others' meanings of the terms, such as intergrade, subspecies, speciation, etc.

Terry,
We just may be able to continue this topic forever without getting anywhere

My Definitions
Speciation: This process can be thought of as being analogous to the process of genetic assimilation of individual phenotypes.

Species:Most usable definitions converge on two major principles
• species are real entities of nature, forming natural groups
• species are evolutionarily independent units; they form a boundary for the spread of alleles — different species have independent evolutionary trajectories.

subspeciesa geographical race, a population with distinctive traits occupying part of the range of the species.

These are very basic definitions on my part intentionally so as not to derail the thought process with tangents

Where I'm getting "my" definitions:

and this one

and I particularly enjoyed this one:
