Question

give a brief description on lung fish's evolution....

Answer 1

hi dear here is the answer

Lungs are homologous to the swim bladder of bony fish. However, it's not that lungs simply evolved from the swim bladders of fish; in fact, the reverse is true. The swim bladders of bony fishes living today, like the lungsof terrestrial vertebrates, are both exapted from primitive lungs.
