Yes.
Evolution , in

By the recombination there has been a change from (relatively) generalized
ancestor
to specialized descendants.

Not the same Iwould agree, but they are comparable to some.
Even the single cell, our mother ovule, or even the legions

True. Again, by the concept of types of organization they are not identical
with free-living single cells, but they share these qualities with many
so-called
parasitic single cells (i.e. disease organisms).
By the way, I don't know
