The Nephilim nod. Their wing feathers move forward in what Bob now recognizes as a Nephilim sign of affirmation. We took specimens very long ago. The ants nod. Ishmael s abdomen throbs as he starts to speak. Humans discovered fossil Pikaia creatures in the Burgess Shale of Canada. They lived around 530 million years before humans. These kinds of creatures were ancestors of the chordates and precursors to vertebrates like yourself. ...

The Burgess shale put paid to the idea that life had only invented shells at the beginning of the Cambrian. Discovered high in the Canadian Rockies by Charles Doolittle Walcott of the Smithsonian Institution in the early years of the twentieth century, this mid-Cambrian shale contains such an astonishing variety and preservation of soft body parts that... 

Cambrian explosion A relatively short interval of rapid intense evolution that supposedly occurred in the early to mid-Cambrian period, some 540 to 520 million years ago. The supposition is based on the sudden appearance in the fossil record from this time of many diverse and novel forms, particularly marine animals, among which can be found representatives of all major modern groups.

Gould, Stephen Jay Paleontologist and evolutionary theorist who wrote Wonderful Life The Burgess Shale and the Nature of History (1990), which argued that if evolution were rewound and replayed like a tape, it would take different paths and life would look very different.

The Burgess Shale is a stratum of Precambrian rock containing a profuse fossil record of weird animal life. 

Cambrian chordates have been documented from two Konservat Lagerstdtten (cases of exceptional soft-tissue preservation)—the Early Cambrian Chengjiang Lagerstdtte of Kunming, South China, and the Middle Cambrian Burgess Shale of British Columbia, Canada. In both cases, the animals interpreted as chordates constitute a very minor part of the faunas, which are dominated by arthropods and a number of worm phyla.
