Lineage, yes.... lineage of life, no!
wiki Wrote:An evolutionary lineage is a sequence of species, that form a line of descent, each new species the direct result of speciation from an immediate ancestral species.[1][2] Lineages are subsets of the evolutionary tree of life. Lineages are often determined by the techniques of molecular systematics.
Anyway, the requirement for new such lineages during our lifetime only shows, once more, how you utterly misunderstand what evolution of animals by natural selection is.... and your dismissal of new lineages in micro-organisms, just shows how uninterested you are to acknowledge actual evidence.
Bacteria don't breed through sex, so discerning one species from another is... tricky... when they are sufficiently close. How can you say that MRSA is the same species as some other bacteria that exists in our normal environment?
Lineage of life is a term I learned in an astrobiology course I took....I did not make this up. Lineages branch off from each others(when they do they are sub lineages), but if you follow all lineages back, they all lead to a single Universal Common Ancestor just as all branches on a tree have a path to the trunk. I suggest you bone up on the Universal Common Ancestor, and Tree of Life.
