Out of here before the thread deteriorates into crevo flames.
1 billion is a newcomer. Diskagma buttonii fossils from S. Africa are dated to ca. 2.2 billion years old.
Very distant ancestors of humans. Most humans have evolved biologically, but not liberals, who still act as intelligent as fungi.
Thanks, seen it, read it, full of holes, not worth the read.
I know no liberal as a fungi.
What about Gus?
Most Liberals are as sharp as a leading edge of a golf ball!!!
Were they marine life, or terrestrial?
Terrestrial; about the size of a match head, but they grew in clusters like meadows.
There's a wikipedia article on them.
I should say, clusters forming a carpet-like ground covering.
Send a few of the 120,000 species of fungi to Mars... let them do their thing...
Ah, one of the culprits in filling our atmosphere with corrosive oxygen.
Not fungi! Nope, they're heterotrophs, like animals! That means that they do not photosynthesize, and must instead derive their metabolic energy from other sources, either as symbionts or parasites.
They consume oxygen, and then emit the plant-food carbon dioxide.
Apparently Diskagna housed a photosymbiont responsible for some of the early oxygenation
Don’t plants require oxygen to metabolize in the absence of light? The net result is more oxygen than carbon dioxide, but they still must metabolize at night.
Is that a question, or a claim? Because... Wikipedia is your friend!
The net result is more oxygen than carbon dioxide, but they still must metabolize at night.
If given a chance, plants would consume all of the oxygen they produce (during daylight, by means of photosynthesis).
It's because, on the whole, they don't get that chance - because they die first - that they yield a net plus of oxygen in the atmosphere. However, if heterotrophic organisms like bacteria, molds, insects, or human beings can get to them - i.e., if they aren't effectively isolated from the biosphere by being buried and locked into geological strata before they can rot, etc. - then all of that oxygen will be consumed by the organisms that rot or otherwise consume them.
