Sentence examples for ancient scenario from inspiring English sources

Gould's descriptions help us appreciate the complexities of resolving the extent to which diverse eyes are monophyletic or polyphyletic, or stated otherwise, the extent to which diverse eyes evolved by the ancient eye scenario (monophyletic evolution) and by the parallel recruitment and convergent scenarios (polyphyletic evolution; Abouheif et al. 1997; Hodin 2000).
