Evolusi

Riset déning Jennifer Clack nuduhaké yèn tetrapoda ing jaman kapungkur mung urip ing banyu lan ora bisa urip ing dharatan. Sadurungé iku, dipercaya yèn iwak kudu munggah menyang dharatan – kanggo golèk pangan utawa golèk banyu nalika banyu panggonan uripé wiwit asat. Dipercaya yèn sabanjuré tuwuh sikil, paru-paru lan pérangan awak liyané supaya bisa urip luwih apik ing dharatan. Habitat tetrapoda ora mung ing banyu tawa. Rawa-rawa kaya, laguna ing pinggir pasisir lan ing délta kali uga dadi habitat liyané.
