The paper only presents mitochondrial DNA analyses.  Several estimates
of divergence time are discussed, all within the last million years.
Nothing is said about the divergence being rapid though.

I don't understand why they mention mating signals in the abstract

see - but the lead author (Jouventin) is an expert on Penguin behaviour.
