Summary[edit]

Description
Русский: Упрощённая филогения, охватывающая переход от рыб к четвероногим и показывающая произошедшие в его ходе основные анатомические изменения. Обратите внимание на существенное увеличение грудной клетки и таза. Рёбра присутствуют у эустеноптерона, но настолько малы, что их трудно увидеть. Таксоны расположены от наиболее приспособленных к воде вверху до наиболее адаптированных к суше внизу. В цветовой кодировке синий цвет обозначает адаптацию к воде, а цвета от желтого до красного обозначают адаптацию к ходьбе и поддержке веса. Размещение акантостеги в продвинутой позиции по отношению к ихтиостеге отражает наличие у неё дельтопекторального гребня. Эустеноптерон модифицирован из Jarvik (1980), тиктаалик — из Shubin et al. (2014), акантостега и ихтиостега — от Ahlberg et al. (2005a, b).
