Is there a word to describe the specific sort of evolution where no

someone why H. erectus can be the ancestor of H. sapiens, with no
branching in between, and how the both can therefore be considered of
the same species in a sense, but that this in no way means that we are
the same.

The term is anagenesis, and the species that are "formed" this way are
referred to as chronospecies. However, nobody these days thinks that
speciation occurs without cladogenesis (splitting).

Why not?
