Bah.  That's old hat.
Pierce Brosnan did that way back in 1995 on the Goldeneye mission.

The most common phenomenon in evolution is that you have some animal
developing a trait that is of benefit in its natural environment, and
such traits tend to get passed on until they are prevalent throughout
the species' population. In such a manner, species may change as a whole
in response to their environment.

But now and again you have populations being separated, and one develops
in another direction than the other (because their natural environments
differ somewhat, or just because one beneficial mutation arises in one
population but not the other). As each population undergoes its own
changes from the original form, they become so different that if they
ever meet again later they can't (or won't) interbreed anymore, and have
thus become different species -- each differing from the original
species in its own way. The original species isn't gone -- it has been
absorbed into the two new species, each of which is better adapted to
its respective habitat than the original form.

Yeah, yeah...  LOL Thanks for that, I just never seem to get the biology
reasoning about why there wouldn't be everything else in between continuing too.
Sure. It makes sense about the changes occurring, as in dog breeding and the
multitude of variations, but likewise it's the curious way it only goes on and
on ever changing yet nothing remains of all the others.

Well, unless you think of all primates as an example of "other" human relatives,
maybe. But there's always the far separation into unique varieties without the
many almost the same ones existing too.

I can figure it must be something I don't understand about life forms
"evolving", just that I get confused about the odd way such change takes place
so decisively with only a certain kind of outcome, leaving all else as failure
to exist.

It's interesting anyhow, either way.

It isn't easy at all and even scientists are struggling with the concept 
in its details. However, see it as a kind of continuous ironing out of 
extremes. The dominant trait prevails and all the others (which are 
still present somehow) are gradually (re-)absorbed or just disappear 
because they are out-competed. There are as many ways in which this can 
happen as nature can imagine (and nature is imaginative) and most happen 
anyway at the molecular level through the gene flow.
