  • As in the case of all the craniota (animals with a skull), the original or primitive ovum

  • Hence we must once more thoroughly understand the palingenetic embryonic features of the lancelet before we go on to consider the cenogenetic forms of the craniota.

  • The gastraea theory shows us how to do this, by representing the embryology of the lowest vertebrate, the skull-less amphioxus, as the original form, and deducing from it, through a series of gradual modifications, the gastrulation and coelomation of the craniota.

    The Evolution of Man — Volume 1

  • Here we find a large body-cavity or visceral cavity in all the craniota.

    The Evolution of Man — Volume 1

  • In prospondylus the ventral gill-heart probably had the simple form in which we still find it in the ascidia and the embryos of the craniota (Figures 1.98 and 1.100 h).

    The Evolution of Man — Volume 1

  • The articulation proceeds in substantially the same way in the other vertebrates, the craniota, starting from the coelom-pouches.

    The Evolution of Man — Volume 1

  • To these we must add at least nine head-vertebrae, which originally (in all the craniota) constitute the skull.

    The Evolution of Man — Volume 1

  • In this the simple development of the invaluable amphioxus once more furnishes the key to the complex and cenogenetically modified embryonic processes of the craniota.

    The Evolution of Man — Volume 1

  • From this primary model of construction we can cenogenetically deduce all the embryonic forms of the other vertebrates, the craniota, by secondary modifications.

    The Evolution of Man — Volume 1

  • In the craniota we always find only one pair of gonads; in the amphioxus several pairs, arranged in succession.
