Common Ancestors

[jordanriver]

How do we know whether or not a common ancestor species still exists.

Not sure what you're getting at here.

"When we find it" would be the standard quip.

Or do you mean how would we identify it?

Welcome to Theologyweb. I see you're new here.
This forum 'Applied Protology' is the creationist forum. The discussions is this particular forum are from the perspective that creation happened, not evolution. The Natural Science forum is for discussions that take into consideration that there may have been evolution and that there may be a natural explanation for what exists.

So, you probably thought I was referring to some ancient fossil or something.

But no, I am asking from a creationist perspective, and referring to the creatures that exist today (i.e, have not gone extinct). As in, canines for example. They all seem to be biologically related and it is assumed that they all must have a common ancestor, as in, some original created canine.
I am asking how do we know or not know whether or not one of the canine species living today is or is not the actual original species from which the other varieties branced from, whether by selective breeding (by humans on purpose) or by natural causes since the original creation by Bible-God (A.K.A. Yahweh/Jesus/the Lord)/.

Thank you and no, I assumed that the heading Protology was there for a reason.

Thank you for clarifying the question.

Purely as observation, I would assume that the original animals are no longer alive.
Due to the commonly held opinion that DNA has only degenerated since the Fall, I also assumed that diversification resulted from lost genetic information and so each generation would become more removed from the original.
Therefore I am interested in answers to this question myself.

An interesting analogy to the change over time in animals or plants since creation can be found in Languages. Try reading ancient English writing. The farther you go back, the harder it is to read. Though some languages have changed more slowly and are readable farther back, others, like English, especially when they received large infusions from another language, change more quickly. Wolves may change slowly, but some interbreeding with dogs has changed the wolves. None that live now would be absolutely identical to the original.
