, 1 – chordaten
Campbell: 34.1
Ontstaan van chordaten: ±550miljoen jaar geleden aan het einde van het Cambrium.
De eersten met een ruggengraat zijn ontstaan uit lancetvisjes die een notochord (chorda, vandaar
chordaten) en een dorsale, holle zenuwstreng (neurale buis) hebben.
De chorda, het notochord
Flexibele staaf die zich bevindt tussen het verteringskanaal en de neurale buis en biedt
skeletsteun.
De meeste volwassen dieren hebben slechts resten van de embryonale chorda, bij mensen
zijn dit de tussenwervelschijven.
Naaste verwanten aan chordaten zijn de stekelhuidigen (echinodermata) en eikelwormen
(hemichordata), die embryologische en larvale kenmerken delen
Chordaten vormen samen met de echinodermata en hemichordata de nieuwmondigen
(=deuterestomia)
Chordaten zijn bilateraal (tweezijdig symmetrisch)
Figure 1 Campbell: 34.2 Phylogeny of living chordates.
Ook gemeenschappelijk aan chordaten (zakpijpen bijv) en echinodermata (zeelelies bijv) is de
sessiele/vastzittende levenswijze: sessiliteit.
