It is hypothesized that the association, section Pharmacosycea, subsection Petenenses evolved in the Southern Hemisphere as assumed by Murray (1985) for Agaoninae, before the Gondwanan break (Weiblen, 2002) and that the Agaoninae ancestor could had been a Hexapus-like wasp; other way, the author hypothesizes that there had been an unknown ancestral Agaoninae-Ficus association, that originated in Eastern Gondwana, in agreement with Berg and Corner (2005); and that subgenus Pharmacosycea connects with an even earlier stock of Ficus, and suggested by Corner (1967).

Hypotheses: We anticipate multiple origins of lichenicolous fungi, partial parallel cladogenesis, and Gondwanan origin for the Cladoniaceae, but current patterns of distribution are probably partly explained by recent dispersal.
50) Whether Old World hepadnaviruses could have been taken to today's South America by the natural barriers formed by the separation of the sub-continent from the Gondwanan supercontinent about 100 million years ago (28) is something that remains unknown.
After the fragmentation of supercontinent Pangaea and the subsequent split of the Laurasian and Gondwanan landmasses, certain groups of amphibians were able to "hitch a ride" from one continent to another.
Permo-Carboniferous (250 million years to 350 million years ago) Gondwanan sediments are well-distributed in the Indian subcontinent, South Africa, Australia, Antarctica and South America, bearing proof that the southern continents were once united in the form of Gondwanaland.
However, many studies of endemic lineages from different Australasian subregions have dated these lineages to ancient Gondwanan ancestors, which appear to have been separated subsequently by vicariance events (e.
