"The Avalon Explosion
Ediacara fossils [575 to 542 million years ago (Ma)] represent Earth's oldest known complex macroscopic life forms, but their morphological history is poorly understood. A comprehensive quantitative analysis of these fossils indicates that the oldest Ediacara assemblage—the Avalon assemblage (575 to 565 Ma)—already encompassed the full range of Ediacara morphospace. A comparable morphospace range was occupied by the subsequent White Sea (560 to 550 Ma) and Nama (550 to 542 Ma) assemblages, although it was populated differently. In contrast, taxonomicrichness increased in the White Sea assemblage and declined in the Nama assemblage. These diversity changes, occurring whilemorphospace range remained relatively constant, led to inverse shifts in morphological variance. The Avalon morphospace expansionmirrors the Cambrian explosion, and both events may reflect similar underlying mechanisms.

Meanwhile, I'm providing a brief timeline for better insight into something that should not be overlooked... great significance for insight into scripture. Epoch Four discusses nothing about the evolution of life on the Earth. It is silent on the matter. It only discusses affairs of the heavens.
So, what's the point if they find traces of life activity between the time the earth brought forth (Heb)"Tender" grass (algae), non-photosynthetic "herb"(fungi) with spores within itself and non-photosynthetic fruiting fungi "trees" with seed(spores) within itself.... (Epoch Three). The fossil record confirms indeed, such things existed.
...and millions of years later, when the Cambrian Explosion occurs... the same burst of diversity Charles Darwin wrote extensively of, is described emphatically in Epoch Five, "Let the waters bring forth abundantly the moving creature...."
The Gap: What happened on earth, between Epoch Three and Epoch Five? Genesis is silent on the matter. There's no discussion of the Earth in Epoch Four.
So, this (albeit, interesting) information is somewhat, irrelevant, beyond some insight into what was taking place during the epoch "God made two great LIGHTS to give light upon the Earth..." as in making the sun go nuclear fusion.
After the sun went nuclear, God commands, "Let the waters bring forth ABUNDANTLY..." and that perplexing observation, went with Charles Darwin to his grave. There's lots of things ommitted from Genesis 1... and only a nit-picker would strain at gnats, expecting mention of them be included.
Whoops, that was Vendian (Late Precambrian). Corrected timeline chart
Unlike Atheists who are perfect, and have "absolute truths," I'm only human and make errors.
The Vendian was the "late precambrian" (650-540 MYA). The sun went nuclear, somewhere between the Vendian (late precambrian), and dawn of the Cambrian.
The fossil record testifies of this with the proliferation of animal life. When the sun is absent, animal life spirals into extinction.
