   Interspecific associations are currently believed to take part in evolution by improving a partner's fitness through integrated endosymbioses or by causing reproductive isolation and subsequent host speciation, such as in the Wolbachia endosymbioses (Nardon and Grenier, 1991; Margulis, 1993a; Bordenstein et al., 2001).

Blankenship, Molecular Mechanisms of Photosynthesis, Wiley Blackwell, 2nd Edition, page 226, Evidence is now overwhelming that several groups of eukaryotic algae originated from a secondary endosymbiosis, in which a eukaryotic alga was incorporated into a second host (Palmer and Delwiche, 1996; Delwiche and Palmer, 1997; Delwiche, 1999; Keeling, 2010, 2013; Curtis et al., 2012).
