Two lifeforms merge into one organism for first time in a billion years
For the first time in at least a billion years, two lifeforms have merged into a single organism. The process, called primary endosymbiosis, has only happened twice in the history of the Earth, with the first time giving rise to all complex life as we know it through mitochondria. The second time that it happened saw the emergence of plants. Now, an international team of scientists have observed the evolutionary event happening between a species of algae commonly found in the ocean and a bacterium. “The first time we think it happened, it gave rise to all complex life,” said Tyler Coale, a postdoctoral researcher at University of California, Santa Cruz, who led the research on one of two recent studies that uncovered the phenomenon. “Everything more complicated than a bacterial cell owes its existence to that event. A billion years ago or so, it happened again with the chloroplast, and that gave us plants.” The process involves the algae engulfing the bacterium and providing it with nutrients, energy and protection in return for functions that it could not previously perform – in this instance, the ability to “fix” nitrogen from the air. The algae then incorporates the bacterium as an internal organ called an organelle, which becomes vital to the host’s ability to function. |

How do we know? A billion years seems like a long time when we been around for a few hundred thousand and don't know how shit got made a few thousand years ago?
|
|
The first thing they thought of was how can we make this into a food for humans.
|
|
|
Thats how you get swamp thing.
I hope they sprayed it with round up. |
|
How soon until someone tries to radiate it, or change it chemically, and we get some creature growing??

I thought this thread was gonna be about the Republican lawmakers merging into Democrat lawmakers. Weird

I’m a this from the video with the dude who claimed to put his sperm with an egg yoke and grew a little squiggly standing up thing?

View Quote When you see statements like "this has only happened twice ever" what they mean to say is "we've only found evidence of this happening twice ever." It doesn't preclude that it has happened elsewhere, only that we haven't found such evidence. And I didn't read the article, but based on the subject matter, I would assume the evidence they have of this occurring (in antiquity) is primarily DNA evidence. |

And how many centuries will it take before it evolves into a something?
|
|
How many civilizations have risen and fell in just the known history of mankind that we have absolutely no knowledge of.
Pretty sure these 'experts' are talking out of their asses. Must be funding time. |
|
|
So, was this a forced process in a lab? And how do they really know it's the first time?
|

This proves there are a lot of mushrooms at UC Santa Cruz and nothing else.

Sounds to me like symbiosis, not a new life form. The stuff about that this is the way things began is pure speculation.

lol, they have no idea. Just trying to earn that grant money.

So all you have to do is come up with a hypothesis where the laws of physics and reality cease to exist…..cuz God would be so crazy that we have to invent another competing crazy where time itself is a slave to infinite mass (idea of something never ending/infinite isn’t crazy i guess). See! God is dead! |

See! God is dead! You also have to ignore the original question, which was about "the beginning". If there's already a singularity, or anything else, that's not the beginning. That's just an event somewhere in a timeline. |

PDF of the paper https://www.cell.com/cell/pdf/S0092-8674(24)00182-X.pdf Overall, our study shows that the size relationship of the N2- fixing cyanobacterium UCYN-A with B. bigelowii is determined by fundamental constraints rooted in the exchange of resources between symbiotic partners, i.e., in a coordinated metabolism. UCYN-A and other N2-fixing spheroid bodies45–47 are ‘‘snap- shots’’ along the spectrum of the evolution of bacterial-derived organelles in eukaryotes. However, how far along this trajectory these N2-fixing spheroid bodies are will ultimately be uncovered by the demonstration of additional organelle properties, such as the coordination of protein import and export. Limitations of the study This study does not unequivocally demonstrate that UCYN-A is an organelle for N2 fixation because, in order to do so, additional experiments would be necessary to show, for instance, protein trafficking and/or gene migration between both symbiotic part- ners, i.e., UCYN-A and B. bigelowii. Moreover, the symbiotic relationship between the UCYN-A2 sublineage and B. bigelowii might be occasionally unstable under undetermined culture conditions, as it has been reported in this and other similar diffi- cult-to-grow N2-fixing symbioses.6,47 Identifying the conditions triggering the instability of these types of symbioses might help us to better understand what makes them stay together in the natural environment. Furthermore, knowing whether UCYN-A can or cannot be cultivated as a free-living population would be very informative in respect of its nature. In this regard, at- tempts to maintain free-living UCYN-A cells have been unsuc- cessful so far, supporting the nitroplast hypothesis, yet further attempts are needed to confirm this observation. --------------------------------------------- From the news article: https://www.independent.co.uk/news/science/evolution-history-algae-plants-agriculture-b2532663.html The process involves the algae engulfing the bacterium and providing it with nutrients, energy and protection in return for functions that it could not previously perform – in this instance, the ability to “fix” nitrogen from the air. The algae then incorporates the bacterium as an internal organ called an organelle, which becomes vital to the host’s ability to function. So if you add something the thing you added it to magically becomes not a (in this case algae of whatever type) ... eh. If you surgically implanted a biological filter into a human's airway that fitered noxious chemicals out, would they be human or not? ---------------------------------- eta; A bacteria goes into an algae and not only do we call it life, we call it a new life form. Conception happens with human sperm and egg and we don't, we swear it isn't even life. The hypocrisy is chokingly thick. |
