tetrapods? Hey we have bandwidth restrictions on humor loops (The kinds of changes that tetraploidy produces in plants would kill most animals -and definitely restrict the breeding potential of any humans, even those aroused by empathy with snail-mating.)

So you investigate and discuss after ascertaining the presence of something that you haven't defined? Weird.
Yeah. Like Newton with light, Galileo with gravity (and moons), Tesla with "electricity", linguists with "language", chemists with "liquids", the old biologists with "species" - onward through the fog.
Definitions are typically the final, crowning acheivement of successful scientific investigation - or any other discussion involving reason and rationality as key players. Not that provisional, ad hoc categories and labels haven't proven themselves useful, along the way.
We seem to have thrown "theism" and "religion" into the same box here, for example - and somehow decided that Marxism and Stalinism and Maoism were none of them religions, even, let alone theistsic ones - I believe without properly defining religion, or "god", at all.

The genes we are talking about are not isolated.
