The marathon started yesterday and you don't even have your running shoes on
yet.

Well lets back back to basics then, so I can get my running shoes on.
Just give me a short list of examples in nature, in any species, where
lets say 30% of the population within that species, has a different
organ or gland than the others in that species, and a brief on how the
physiology design differs within that group.
As a starting point for discussion.

Can you think of an organ that you don't share with a dolphin?

Mark

I'm not that knowledgeable to know the differences but why do they all
look alike, and why are they all from the design mold?

Because they are all descended from a common ancestor.

Who is it, that one point decides ok, this is the mold for a dolphin,
and all dolphins will follow this mold?

There is no decision involved. All dolphins are descended from a
common ancestor.

Why not two common ancestors or a bunch of equally valid dolphin
designs with differing physiology?

In fact, some species arise from hybridization of two species.
Particularly in plants. Allopolyploidization is the fancy term.



Why is there but one design mold, for every species, which defines the
species?

First you need to understand that "dolphin" is not a species, but a
group of related species. So asking that question wrt dolphins makes
no sense. Dolphins closest cousins, of course, are whales. And
dolphins and whales share a good chunk of what you consider a "mold".

If the process by which you get different designs, is modified DNA,
then probably we have already made lots of new animals I suspect, now
that we know what DNA is. I suppose we have been bashing up DNA like
crazy the way nature does to make some new animals of our own. When
can we see them?

Most evolutionary change involves fixation of alternate alleles at
selectively neutral sites.

So we have a common ancestor, and so now billions of generations
later, here we are. In one person, we will say, by some fluke of
nature they develop an improvement to the genome, through natural
selection after a strand of DNA is hit by a cosmic ray.
Now then they develop a very good horn on the top of their head and
doctors don't remove it, and if that person person has offspring it
will develop that horn because it ends up creating a dominant gene for
this marvelous horn and it looks nice. So then how does that person
now become the common ancestor so that 2 million years from now
everyone will have that horn?
