Did the diversity of lens-containing eyes evolve from one ancestral eye (monophyletic evolution) or from multiple, independently derived eyes (polyphyletic evolution)? Monophyletic evolution would make diverse eyes homologous (inherited similarities from a common ancestor); polyphyletic evolution would make eyes homoplasious (independently acquired similarities). Historically, anatomical and developmental differences among eyes of different species favored homoplasy; however, recent molecular… CONTINUE READING
