This is fantastic reference for programmers and developers for a serious project on ediacaran life and environments in that era for the gaming industry. We need more of these presentations ( not just as inspiration) but as a resource of examined data- turned into believable concepts / theory. Outstanding !
To the guys question about predation: could have been that bilaterian predation pushed the ediacarans into areas of sea with less oxygen that the predators couldn't enter? I feel that is where he was trying to go. For example, you have filter feeding predators like Auroralumina attenboroughii that have poor preservation and representation. The could have been eating all the baby vendobiotes.
Step back a moment and think about "all the basic body plans" for modern animals exploding in the Cambrian, AREN'T THEY ALL REALLY JUST COMPLICATED WORMS? I just don't see that complexity and diversity NOT being preceded by Worm Wars, ie, enough predation to cause that development and diversity. That said, the "late Ediacaran" is a LONG period of time, the Worm Wars could have been at the very end of the Ediacaran, but dunno, macro worm tracks were possibly found back in the Cryogenian, and worms evolving, and predating, as sub macro creatures likely wouldn't leave a trace. Just saying.
I like the conclusions but I still feel it’s putting the effect before the cause. To me, if we’re seeing higher amounts of oxygen and low surface-area to volume (or bigger) animals in the White Sea Assemblage transitioning to lower amounts of oxygen and higher surface-area to volume (or smaller animals then we may be seeing a boom and bust cycle. I can’t remember which lecture I’d heard it from but it was pointed out that trace fossils of bacterial mat grazers started very random and aimless and became more efficient throughout the Ediacaran. At the very least that hints at population increase and population specialization during the White Sea Assemblage that collapsed into smaller more generic animals during the Nama Assemblage. I think that pushes back the driver of evolution during the Cambrian, intensive predation of animals upon other animals, into the latest Ediacaran. Thus the only real difference is that the earliest Cambrian is showing us evidence of animals reactions to the desperate conditions of the Nama Assemblage and an appearance of predation of biomineralization and bioturbation.
Is there a systematic bias againat the preservation of shallow-water ecosystems of "Avalon" age? Do you think there was there a genuine absence of "White Sea"-type animals living in shallow water during that time, or do you expect that the faunas overlapped with each other?
From an amateur eye, I think you are looking at the results of the Frankenstein progression. For billions of years there wasn't oxygen and single cell organisms could clone and prosper. The accumulation of oxygen became toxic to them, and through cloning they passed on the oxygen deformation to the clones decreasing the clones life span. Which is why sexual reproduction evolved through cells splitting only half their code and requiring a second partial code from another in order to break the oxygen deformation inheritance. Anyways there's banded iron formations from several events prior and throughout the time you are looking at. The constant fluctuating oxygen levels and the struggle for evolution to adapt in altering conditions left it grasping at every direction and likely some blue prints just didn't last. You should consider volcanism, hydrothermal vents and meteor impacts as a combination of environmental services influences and failed biological attempts to adjust. You can't have worms with no mouths or buttholes surviving through energy created by ancient bacteria inside them without major influences on a variety of magnitudes. Scientist need to broaden their time focus and understand geologic time in ancient history is all relevant to any particular time period. There wouldn't be a tsunami recorded in the early Cambrian bonneterre formation of Missouri if there wasn't geologic driving forces involved. Earth's evolution and life's evolution are hand and hand. Y'all have proven that much. There was a great struggle when oxygen formed in the water and the over oxygenated material of the ocean occured before the atmosphere. Everything had to overcome that and when it did, it had it's oxygen stripped away.. repeat that a few times while trying to recode and evolve. The answers are out there. And everything is evidence. Cold, hot, oxygen fluctuations, continental formations, ancient bacteria from asteroid impacts deep in oceanic crust mixing with evolved bacterias in the sub sedimentary ocean layers, it's endless. Great start to piling evidence and pushing for more answers ❤❤❤
Oh, thank you for bringing this up! I counted 53 um & uh’s in the first 5 minutes and it was very distracting from an extremely interesting topic. I am neither a writer nor a college grad, but it was driving me nuts.
I find it hilarious that a distinguished scientist, who searches the globe for biological truth, feels compelled to play along with the latest social psychosis de jour by feeling it necessary to announce that he's a "he/him". Too funny.

Love hearing the latest research on these bizarre beasties, nice work!

Like the enthusiasm, but, as a writer, I'm bothered by the "uhms." Even my level, undergrad lib arts, we rid ourselves of those before graduating.
No one cares
Whaaat? Such a dumb comment. This is an excellent presentation of a highly complex topic. And you obviously haven't studied linguistics.

Didn't wanna say it but... yeah...
Gender is as real as we make it
Brain dead take. You should look in to what science says about gender and biological sex.
