15-P031 Evolution of bivalve bodyplan
Vertebrate ancestors would have increased their egg size to store yolk, and the increase is considered to have altered the cleavage pattern and germ layer formation. Amphibian holoblastic cleavage in which all blastomeres contribute to any one of the three primary germ layers has been widely thought to be a developmental pattern in the stem lineage of vertebrates, and meroblastic cleavage to ha...

extant limpet. In addition, bivalves also acquired a novel structure, adducter muscle to close the separated shell plate. Because the two novel structures, the separated shell plate and the adducter muscle appear early embryonic stage, their evolution should be understood as a modification of early development. To understand the evolution of bivalve bodyplan, we have traced the cleavage pattern...
