It is suggested that contraction and fragmentation of the Pan-African forest coupled to an increase in open habitats (savannah, grassland, heathland), since the Oligocene played a key role in diversification of this group through vicariance.
Rise of oceanographic barriers in continuous populations of a cetacean: the genetic structure of harbour porpoises in Old World waters
This work applies a combination of recent individual-based landscape genetic approaches to investigate the population genetic structure of a highly mobile extensive range cetacean, the harbour porpoise in the eastern North Atlantic, with regards to oceanographic characteristics that could constrain its dispersal.
Phylogeography of the widespread African puff adder (Bitis arietans) reveals multiple Pleistocene refugia in southern Africa
This study reveals a complex history of refugial isolation and secondary expansion for puff adders and a mosaic of isolated refugia in southern Africa and identifies key differences between the processes that drove isolation in B. arietans and those hypothesized for sympatric savannah mammals.
Speciation and radiations track climate transitions since the Miocene Climatic Optimum: a case study of southern African chameleons
Overall, dwarf chameleons have experienced a shift in habitat types, with recent radiations occupying open habitats, and older lineages persisting in relictual forested habitats, as shown by chameleon species richness and phylogenetic diversity.
Climate change drives speciation in the southern rock agama (Agama atra) in the Cape Floristic Region, South Africa
Agama atra shows at least four distinct genetic provinces within the Cape Floristic Region, which highlights the conservation importance of this biologically diverse area.

It is suggested that the origins of many present‐day lineages were founded in the Plio–Pleistocene, a time period that corresponds to the reduction of forests in the region and the establishment of the fynbos biome.
Phylogenetics of the southern African dwarf chameleons, Bradypodion (Squamata: Chamaeleonidae).

These alternative hypotheses using data for a diverse genus of East African forest chameleons, Kinyongia, showed that accumulation of new species due to radiation within refugial habitats or retention of older palaeoendemic species in stable refugia is possible.
Population structure and historical demography of eastern North Atlantic harbour porpoises inferred through mtDNA sequences
The results suggest that harbour porpoises within the eastern North Atlantic show geographic structuring as a consequence of limited gene flow along the coast, and their historical biogeography can be interpreted in light of demographic changes that have influenced the evolutionary patterns observed in the mtDNA sequences.
