This is the saga of Cambrius son of Bilater
Cambrius was a great planula among many. His city was small and he knew right from wrong and left from right
Among his millions of siblings there was Xenus
The sons of Xenus held fast to his traditions. To this day they keep their traditions
Among the sons of Xenus there was Roscoff the great. The farmer who married Tetraselma the alga. Together they became Patriarch and Matriarch of the Roscoff worms.
Cambrius sought to emulate the sons of Ctenopher. To eat but not vomit and swim without fear.
While he failed his firstborn took over
Nephrus son of Cambrius would change everything
Nephrus was a great king. And so he grew his city greatly.
He folded his gut inward and through. Pockets of endoderm mixed with mesoglea, and so the mesoderm was born. His body was hollow. A coelom, a chamber where he build his organs
In his coelom he built his kidneys, his nephridia, and from his ectoderm he brought in a great telegraph network connecting every citizen together
Like the sons of Cubos he built for his city a great priesthood of astrologers.
The astrologers came together in pits and looked to the stars for guidance
With the blessing of Lord Carotenus and the incantation PAX6 they built eyes for themselves
Nephrus bore two sons: Protos and Dutrus
Each disagreed on the legacy of their father
Protos saw the first hole as the mouth and the second as the anus. He saw the Mesoderm as being first and foremost Mesoglea. His mouth was full of tentacles like his fathers before him.
O ye heathen is the anus not the locus of progress? For generations we bathed in our own filth. But that is no more, now we keep our mouths clean and eat all the nutritious food we find. The endoderm is the endoderm, the ectoderm is the ectoderm, and the Mesoderm the mesoderm. Aye these three layers shall never mix for they are the foundation of civilization.
Dutrus saw the second hole as the mouth, and the first as the anus. He saw the Mesoderm as being beyond the Mesoglea. A true reunion of the fisherman and shieldmaidens of old in the time of Metazo. His mouth was like a sponge, with gills and pores to filter the future.
O ye heathen is the mouth not the locus of progress? What we take into ourselves is our future and what we expel is the past. By reuniting Choanoderm and Archaeocytes are we not bringing a glorious future.
And so war began. Whose vision would shape the Cambrian legacy? Only time would tell.
Each son bore two more sons:
Dutrus bore Dietrich and Saccorhytus
Protos bore Ectus and Spiralius
Saccorhytus was strange. With no anus he did nothing. So the legacy of Dutrus was continued by Dietrich the loyal
The sons of Dutrus are famous across the world for their heads, but Dietrich had no head
Dietrich built for himself a tail to move through the ground. With a tail and two nerve cords he grew prosperous like none before. He settled and built a great colony
Spiralius was a great man. He held true to the values of his father
He built his city as a trochophore and was the greatest fisherman
With great tentacles he was a better fisherman than any before him
He settled and became wealthy and prosperous
Ectus was a resentful secondborn
So he sought to be the greatest among the sons of Cambrius. He made his tentacles into ferocious teeth, and shed his skin to maintain his youth. With great muscles he launched at his prey
Ectus declared war on Dutrus and Spiralius alike, eating all he could find.
O ye eldest sons beware. For the legacy of Cambrius belongs to the strong.
And so the sons of Dutrus, the sons of Spiralius, and the sons of Ectus were brought into war. These three great tribes would define history. So began the Cambrian explosion
