Examples
“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.”
“Here we find a large body-cavity or visceral cavity in all the craniota.”
“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 articulation proceeds in substantially the same way in the other vertebrates, the craniota, starting from the coelom-pouches.”
“To these we must add at least nine head-vertebrae, which originally (in all the craniota) constitute the skull.”
“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.”
“From this primary model of construction we can cenogenetically deduce all the embryonic forms of the other vertebrates, the craniota, by secondary modifications.”
“In the craniota we always find only one pair of gonads; in the amphioxus several pairs, arranged in succession.”
