Meredith E. Protas and colleagues have explored how convergent evolution—a phenomenon that occurs when the same trait evolves independently in two reproductively separate lineages—can result from a genetic mechanism shared by both lineages. Meanwhile, Bas J. Zwaan and colleagues have investigated how convergence occurs through different genetic mechanisms, but the relative prevalence of convergence through shared and different genetic processes is still poorly understood. This motivated biologist Delbert A. Green II and Cassandra G. Extavour to evaluate both types of convergence in a single study for their 2012 paper.

Before Green and Extavour's study, convergence evolution was assumed to require a shared genetic mechanism between two lineages that shared the trait.

Green and Extavour's study was conducted using data from the studies by Protas and colleagues and Zwaan and colleagues.

Green and Extavour's study addresses convergent evolution more comprehensively than the studies by Protas and colleagues and Zwaan and colleagues do.

Both the study by Protas and colleagues and that by Green and Extavour compare convergence through shared genetic mechanism to convergence through different genetic mechanisms.
