I guess you are thinking of the production of hydrogen by electrolysis of water. In this process we talk of the hydrogen being 'evolved'. It is nothing to do with Darwinian evolution
how made hydrogen how made hydrogen how made hydrogen how made hydrogen
Evolution or change
Hydrogen. The lightest element.
H2 is molecular hydrogen. H2S is hydrogen sulfide and is extremely toxic.
Hydrogen is not poisonous.
place a lit splint into a test tube if you hear a squeaky pop sound it is hydrogen.
Scientist believe that stellar evolution contained only hydrogen and then helium.
No. To convert it to "Hydrogen" requires a fuel cell and appropriate oxygen / hydrogen separator components. Technology has not reached that point of evolution at this time.
The fact that each star starts out with all the hydrogen that its ever going to have.
No, the gas produced is a result of the chemical reaction.
Everything except Hydrogen & Helium (and part of the Helium is also formed within stars).
Probably either helium or carbon, depending on how far the Sun's evolution goes. There will still be plenty of hydrogen; even when hydrogen fusion ceases, it won't be because it was all gone.

Yes, Mars does have traces of hydrogen in its atmosphere. The presence of hydrogen on Mars has been detected through various observations and scientific instruments, including the Mars Atmosphere and Volatile Evolution (MAVEN) mission. However, the amount of hydrogen on Mars is relatively small compared to other elements.

At first, such a star will convert hydrogen-1 into helium-4; later, it will convert helium-4 into heavier atoms, up to about iron.
