Experimental hybridization and reproductive isolation between two sympatric species of tephritid fruit flies in the Anastrepha fraterculus species group [PDF]
, 2017 Among tephritid fruit flies, hybridzation has been found to produce local adaptationand speciation, and in the case of pest species, induce behavioral and ecological alterations that can adversely impact efficient pest management. The fraterculus species

Evolution of cyanobacterial morphotypes
Communicative & Integrative Biology, 2011 Within prokaryotes cyanobacteria represent one of the oldest and morphologically most diverse phyla on Earth. The rise of oxygen levels in the atmosphere 2.32–2.45 billion years ago is assigned to the photosynthetic activity of ancestors from this phylum.
