Their ancestors, and so on and so on.
This is the same for all living things.
Marshall think of this, we know where you came from right? Your parents, and your parents came from their parents, and this continues back over hundreds of millions of years.
Why wouldn't it? Do we have any reason to believe that somewhere along your ancestral line things worked differently?
Over these hundreds of millions of years naturally new generations will be slightly different, parents don't create clones and hundreds of millions of years is a long time.
The differences will get greater and greater in each branch of the family tree, and new branches keep forming.
You should know all this, look for your own family tree and then try to imagine if it kept going back for millions of years and it showed all the directions as opposed to just your families.
My belief is that the root of human existence would be the same root for every living thing on earth's existence.
You and your cousin share the common ancestor of your grandparents, your grandparents and their cousins share the common ancestor of their grandparents.
Why would this system be different at some stage in history?
Gorrillas and humans both shared a great great greatx 1000+ grandparent. Humans and sharks both share a great, great , great x 10 000 000+ grandparent etc.
