Synthesis and Conclusion

Show Summary Details


This concluding chapter summarizes the data on the reconstruction of the history of the conquest of land by vertebrates, arguing that all known Devonian stegocephalians were primitively aquatic and that aquatic to terrestrial lifestyles evolved in a complex way. It also presents the three hypotheses as to why vertebrates ventured landward (i.e., to seek prey, to escape predators, or to raise body temperature), and suggests that these selective pressures have played a role in the evolution of terrestrial vertebrates.

Keywords: vertebrates; stegocephalians; aquatic lifestyle; terrestrial lifestyle; evolution; terrestrial vertebrates
