  • Adaptive radiation of tetrapod vertebrates into terrestrial environments depended upon the successful emancipation of embryonic development from the aquatic "crib" of the Amphibia. The cleidoic egg of birds and the viviparous development of placental mammals are often cited by physiologists as major morphologic adaptations of the most successful terrestrial vertebrates to xeric conditions (Baldwin, 1964; Needham, 1938; Yapp, 1960). However, this interpretation of the initial adaptive… CONTINUE READING
