This is a long read and probably boring if you're not into science, but I found it incredibly fascinating. It's the story of Leonid Moroz's research into jellyfish-like animals known as ctenophores and how they prove life and intelligence can evolve in multiple ways. It also suggests that life and complex systems are probably an inevitability, regardless of chemical composition or structural development. Worth the read if you have the time.

How frustrating it is for anyone with an idea/research to know(much like Tesla/Edison in this case), that some established cocksuckers are laying in wait at all times ready to publish your shit after polishing touches.

There's a lot here, but first was how close to home this hit, one of my best jobs was in Friday Harbor, in fact I wouldn't have made my own unique lives without that experience.

Although these creatures lack the conventional nervous systems and building blocks to todays life, and without a doubt are "alien" in that regard, it always blows me away when the timeline is assumed that these would be among the first, rather than the latter.
Especially considering scientific discovery changes the landscape daily.
Perhaps like this creature has demonstrated, scientists should approach the biology of the earth and it's origins in the same alien manner, throwing away the traditional timeline that might be constricting; nothing to lose there.

If this structure were before sponges, interesting how they continue to interact and live through a purported 600 million year span, mimicking other creatures that seemingly comprise neither the ability to detect it's "alienation" , or it's ability to extinguish a threat unknown, perhaps not seeing it as a threat?

I found this statement important, because it's solidified my own wonder, whereas science, as broad a field it is, inherently lacks imagination in favor of tunnel-vision when explaining the origin of life...

"This ‘shadow biosphere’ would be difficult to detect, since it might not contain DNA, proteins or the other molecules that we rely on to detect life."

And therein lies the parallel.

I swear, James Cameron just reads obscure journals then pops out sci-fi's, lol.

Cool shit.
Even cooler where he is now from where he came; promising.

Like the article.
I couldn't seem to rationalize the idea that ctenophores must be earlier than sponges.

They simply must have developed from a separate branch or a unique tree. I don't see a requirement that said branch must have been earlier than the sponge branch, only that the sponge branch is obviously more dominant currently.

Instead of writing all the reasons why I found this.

The ctenophore lineage is older than sponges? That cannot be right! Or can it? | Journal of Experimental Biology

It's thorough. And the short answer is that various evolutionary biology data, not presented in the article above, moves the sponge more modern. There are fewer assumptions needed for ctenophores to be earlier. And so data and Occam'z razor win the day.

.
The same passage on the shadow biosphere activated my imagination. It really has fascinating implications for everything from how we look for life both on earth and outside of it.
