A merger between two simple creatures created the prokaryotes - the first creatures that could carry out photosynthesis and oxygenate the earth. This process later allowed the development of all complex creatures
Humans could not walk the earth today if it were not for an ancient fusion between two single-celled creatures called prokaryotes, according to research funded by NASA.
By comparing the proteins in more than 3,000 different types of prokaryotes - a type of single-celled organism without a nucleus - molecular biologist James Lake of the University of California and the Center for Astrobiology in Los Angeles showed that two main types of relatively simple bacteria merged together more than -2.5 billion years. Lake's research revealed a new trajectory for the evolution of life on Earth. This insight was published in the August 20 online version of the journal Nature.
This internal symbiosis, or the fusion of the two cells, allowed the development of a stable and successful creature with the ability to use energy from sunlight through photosynthesis. Further evolutionary development led to photosynthetic organisms that produced oxygen as a by-product. The oxidation of the Earth's atmosphere thanks to that Louis product, affected the evolution of life, and led to the development of more complex creatures that consume oxygen, which are the ancestors of modern creatures that breathe oxygen, including humans.
"Superior life could not have developed without this event," Lake said. "These are very important creatures. At the time two early prokaryotes evolved, there was no oxygen in the atmosphere. Humans could not live. No oxygen-breathing creature could live.
The genetic machinery and structural organization of these two organisms merged and created a new type of prokaryote - a double-membrane prokaryote, cyanobacteria, which became the primary oxygen producer on Earth, and which produced enough oxygen to change the chemical composition of the atmosphere and prepare the understanding for the evolution of the more complex organisms - Devourers of life and plants.
This work provides an advance in our understanding of how a group of creatures managed to learn to utilize the sun and cause the greatest environmental change on Earth ever, a good result in this case.” said Carl Pilcher, director of NASA's Astrobiology Institute at NASA's Ames Research Center in California, which co-funded the study with the National Science Foundation in Arlington, Virginia.
The NASA Astrobiology Institute is a partnership between NASA, 14 American groups and six international groups. The aim of the institute is to promote, carry out and lead interdisciplinary research in astrobiology, to guide a new generation of researchers in the field, and to share the excitement of astrobiology with students of all ages.
The institute is part of NASA's Astrobiology Program based in Washington. The program supports research about the origin of life, its evolution, its distribution and the future of life on Earth, as well as about the potential for life elsewhere in the universe.

right
But I surfed two browsers together
And I came across and just transferred
Regarding the second link, these are quality pictures from Mars
Really special photos
What's going on here?
Have you heard the word prokaryotes so now everything is prokaryotes?
Want to take care of Mars?
They have already thought about it and this is the summary of the conclusions:

Raul:
Why didn't you bring the links in the article that are relevant to them?
In this article they will get lost because no one will think to look for information about galaxy collision in the article dealing with prokaryote collision.
Roy, in our world the oxygen produced by organisms produces two H2O molecules.
And this is one of the reasons why the presence of water is the main factor in the existence of life outside the Earth.
First they will take care of the DHAWA
There should be genetic engineering for prokaryotic organisms that will lower the high carbon level
and increase oxygen production.
The interesting question is what do they produce oxygen from? Pretty sure it can be used to prevent and treat infections
By and large, your (old) idea of populating Mars with oxygen-producing prokaryotes is correct, but not at the moment. The potential of discovering life that has been cut off from us for billions of years is far more valuable than starting right now to pollute the universe with Earth-made life. If it turns out that there is no life on Mars (I will always be doubtful, also regarding our moon by the way) or then we can start thinking about genetic engineering and the controlled introduction of life in a greenhouse the size of a planet.

Refresh... I was just thinking about this.. Let this plan be implemented on Mars using a space vehicle or something.. and by the time astronauts get there there will be growth there that will provide oxygen.. =] ..
It's not me censoring, it's the Ekismet.
But if I didn't use it, you see a lot of links to buy Viagra.
Father, I don't understand why you censored the link I gave to download the pictures of Mars
There are 416 quality photos
Is this against the rules or something?
Regarding the article
Does this mean that evolution only started 2.5 billion years ago?
We need to put a lot of prokaryotes on Mars to build an atmosphere with oxygen, and genetically engineer them to stop the production of oxygen when the amount of oxygen in the atmosphere of Mars reaches the amount of oxygen in the Earth's atmosphere.
another thing i ran into there is a huge collection of pictures from mars
which was taken since 2004 to 2009
example

the collection can be downloaded from here

in the bottom of the page click on
"or download with very slow speed"
my explorer does me problem with the hebrew
well enjoy!
For astronomy fans, you can download a 40-minute movie in HD quality

Wait sixty seconds and click download
Yes…. ZA is not without its problems, but it is interesting. Of course, it should be noted that photosynthesis was invented long ago and probably more than once. If there was such a fusion, its source is, in my opinion, in green sulfur bacteria and red bacteria, each of which has one of the photosystems we know from cyanobacteria or plants ( eukaryotes). This is a very logical assumption, but it is difficult to prove. The proof of a large sharing of proteins is strong, but it can also be said that it is a little trivial - obviously, if you have a system that consists of X and Zd, then you will probably have protein overlaps with those who have only X and with those who have If only Z. And if you want the systems to work properly then the genes and their expression products should be conservative or at least such that they will not impair the efficiency and ability to compete with other light energy harvesters.
We owe our gratitude to cyanobacteria - that's right. But they started as a fusion startup of (at least) two other startups, also successful - although a little less energetically efficient individually.
