Re: Nested clades
How can we have all the life forms on earth we do today when we started with one life form as a common ancestor, without those boundaries being crossed?
Because the boundaries didn't exist to be crossed. The boundaries, themselves, emerged as complexity increased and the clades formed.

Re: Lineage is biology; biology is lineage.
If that statement is true, how can any evolutionist understand anything about any creature as he does not know how life began to exist?
If you do not know how something began to exist, how can you know the linage of it?
By using what you do know. If we have some lineage:
A --> B --> C --> D --> E --> F
Where A is where it began to exist and F is today, you could know all sorts of stuff about:
B --> C --> D --> E --> F
While knowing nothing about A
You could easily follow the stories in the Bible, like say the lineage of the Exodus, without knowing anything about Genesis.

Re: Nested clades
The first life form formed a clade.
call "Life".
The boundry existed.
That life form could never cease to be that kind of life form.
You're right... all life is still life.
But more specifc clads didn't emerge until enough difference evolved for the boundary to be drawn. While those differences were accumulating, no boundaries were being crossed, and once the boundaries had emerged, they were no longer crossed. Newer, more specific, boundaries countinued to emerge though.
