i was thinking today about psilocybin... as you do.... and the very tough spore cases that they possess.. this would enable animals to eat these mushrooms, and the spores to pass through their digestive tract in one piece, so as to be transported to new areas... not just copleandias or mushrooms that grow from dung... but any psilocybe, although other mushrooms have this capability as well... maybe another species of animal was fond of these mushrooms, and had very strong stomach acid, so the psilocybes needed to be able to withstand these pressures in order to survive their animal transport...
maybe dinosaurs were fond of tripping.... ?
another theory about chemical overlap in psilocybes... i was thinking today about stinging nettles, they release the right chemicals in order to provoke a reaction across the animal kingdom, a chemical that envokes a poisonous reaction... stinging nettles were selected because they were able to repel potential attackers.... in this way, psilocybe might have had a past gourmet that appreciated its psychedelic nature and increased its presence... maybe monkeys eat and ate them.... im a believer in the australopithecine psilocybin theory btw.... i will come back to this when brazil isnt playing germany ;]

I do.
If not, we are the victims of one of the universe's biggest practical jokes ever. Well, that may be true in any case.

Thats an interesting theory, but I tend to lead toward no. All the info I've read about spores says they are viable at most 2 years. I don't know how they would react in space. Could I trouble someone for the mass of say, a cubensis spore?
Also, isn't space really cold? What is the lower threshold of temp for spore survival?

Space is, on average, around 4 degrees above absolute zero (that's about -270 degrees Celcius). That is damned cold for anything to survive in.
But that's not the only problem with spores surviving for any extended period in space. Next you have the fact that if an object is anywhere in direct view of a star from a resonable distance (say, the Earth's orbit) that object will be heated to thousands of degrees Celcius. So now the spore is either extremely cold or extremely hot. Then there's the whole radiation issue. Space is flooded with extremely energetic (and hence dangerous) radiation from stars, black holes, neutron stars, and just about everything else out there. We are protected from cosmic radiation by the Earth's atmosphere, but once you are outside it you are in for a big dose of radiation. I once heard that if you spent one week in orbit around Earth you would receive as much radiation as a worker in a nuclear power plant receives in a year. The radiation belts around Jupiter are tens to hundreds of times the strength that it takes to kill a human instantly.
So I'd say the chances of a spore, which is a delicate form of life, surviving in space for a month (let alone years) is pretty slim.
And what would the spore do once it landed on Earth? Life on Earth is very symbiotic. Mushrooms in general will thrive on a certain form of host matter and will not grow at all on most others. What are the chances that a spore would land on a planet in the right place, on the right host matter that it needed for growth.
I think this theory is just another product of a good imagination. Fun to think about...but not very realistic.

Did you read the link I put in the very first post?
Here is some:
'UV radiation from the Sun killed nearly all the spores, confirming that single bacteria would not survive long enough in space to travel from one planet to another. The same happened when the spores were behind a quartz window, so the researchers did the rest of their experiments with the spores confined under quartz.
To test whether meteorites might protect the bacteria on their journey through space, Horneck and her colleagues mixed samples of 50 million spores with particles of clay, red sandstone, Martian meteorite or simulated Martian soil, to make small lumps a centimetre across. In most of the samples, between 10,000 and 100,000 spores of the original 50 million survived. And when mixed with red sandstone, nearly all survived. The results suggest that even meteorites as small as a centimetre in diameter could carry life from one planet to another, if they completed the journey within a few years. '
So, a meteorite 1cm in diameter could carry spores. What about the meteor that are a few hundred feet that have hit the earth........

I have never heard anything like that, can you post a link/referance?
There is little data on temperatures spores can survive. Does anybody know the extremes? Anybody done any tests? Maybe someone could post a link post a link?
Good luck

and what of the huge explosion as it hits the earth? or the water it is more likely to land in?
no very likely. sorry.
the chemicals (building blocks) that are required to start life may well have been delivered by comets/meteors but actual life won't survive those extremes.

Life is tougher than you think, the have found bacteria growing on a camera lens, left on the moon by one of the Apollo missions.

The camera lense wasn't subjected to tens of thousands of degrees as it plummeted through an atmosphere. Bacteria surviving in a stable environment is fine, but when you go to the extremes nothing will live. There's a reason they have those black tiles on the bottom of the space shuttle, and a reason they have to replace them so often. The heat generated from just gliding into the atmosphere (as opposed to punching right through, like a metor usually does) is far beyond what it takes to vapourize even the strongest metal.
Can life survive that? No.
You're right, though. Life is tougher than most people think. Bacteria can live on thermal vents on the bottom of the ocean, just a few inches away from water temps of hundreds of degrees. But nothing lives in that hot water. Nothing. Close to it, sure, but not right in it.

Im not replying to trendal specifically i just forgot how to post. Does anyone know the chances of a single spore let alone two spores traveling though space on anything but a rock and then hitting earth from god knows where, surviving being burnt up or vaporized on impact, if the rock is say, not a rock and instead an asteroid lol and that is the only way I could see spores arriving here. A tiny spore would drift through space for an eternity before hitting a planet let alone a hospitable one. Scientists don't fully agree on whether or not life originated on earth, the only way I could see mushrooms here on earth arriving from another planet is in the form of a distant cousin, life isn't 90 million years old, so it wouldn't even be a spore at that point, it'd be some early life form...So yes technicallyyyy mushrooms may have arrived from space but this claim is disregarding the post on here about its dna of which can be traced back to the earliest life forms on earth, and the possibility that life may have not come from space, if you wanted to get technical. Yeah its an interesting idea at first but when you think about it it doesnt make much sense. Id also like to point out, now i am replying to trendal, that a spore wouldn't generate basically any friction which is why shuttles heat up. lol.
