Is there a word to describe the specific sort of evolution where no
branching has occurred? I'm having a difficult time explaining to
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.
Chronospeciation, I think.

Anagenesis.

As far as I know, there is no term "chronospeciation". There are
chronospecies, but those are just arbitrary divisions of an evolving
(i.e. anagenetic) lineage.

The term was coined, I believe, by T Neville George in the 1956 symposium _The
Speices Concept in Palaeontology_. No mention there or elsewhere of
"chronospeciation" AFAICT.
