Has the Origins of Human Life on Earth Been Discovered?

[Dryson]

The article discusses the impactor site of the asteroid that killed on the dinosaurs.

Since humans haven't been discovered to have existed on Earth during the reign of the dinosaurs, then perhaps the asteroid chunks found at the impact site will finally reveal the originating location of where human life came from.

Wouldn't 65 million years be a rather short time for humans to evolve from a simple organism from an asteroid?

 

[StarCruiser]

Cause and effect - Dryson just doesn't get it...

 

[Asbo Zaprudder]

It would be easier to argue with a creationist or even a flat-earther.

 

[Santaman]

I'll try.. Dinosaur: cold blooded, Megazotrodon etc: warm blooded, ASTERROID BOOOOOOOOOOOOOOM!! cold blooded kicked the bucket, now itty bitty warm blooded RULEZ TEH UNIVERSE!! lots of evolution!!! Tadaa huuuuuman!

 

[Asbo Zaprudder]

What I don't get is why establishing a possible origin point for the asteroid that collided with Earth 65 or so million years ago is seemingly being linked with where modern homo sapiens evolved some 250 thousand years ago. There have been smaller impacts and also volcanic events and climate change in the past million years that have had a greater effect. Sure the stage was cleared worldwide by removing all large fauna but the event didn't ensure the rise of a hominid species. The genetic dice have been constantly been rethrown for vertebrates over a couple of hundred million years - the evolution of a sapient species was inevitable eventually in at least one branch of the multiverse. We find ourselves existing and ridiculously think we're special.

 

[BillJ]

...and ridiculously think we're special.

The last 18 months has completely squashed any thought of this in my mind.

What - ya think Einstein might have underestimated the amount of Human stupidity in the Universe (vs. Hydrogen)?

The two are not mutually exclusive

The asteroid that collided with the Earth that killed the Dino's is important because material composition of asteroid might have been responsible for causing the split in money DNA that became human DNA along with causing a mutation to happen that also caused the early human/monkey brain, the brain present right after humans split from monkeys, to begin to enlarge.

Most non-humam life on Earth has been tracked to very in the evolution of Earth, millions of years before humans. If humans had a footprint and had been present on the Earth at the same time as early life, there would have been tell tale,signs of human DNA.

Monkeys have been around for about 30 million years compared to humans being around for 300 thousand years, approx.

If the dino killing asteroid struck 65 million years ago, monkeys have been around for 30 million and humans for 300k years, then the asteroid does appear to have caused a shift in the DNA of the animal species that was the monkeys ancestors that existed during the time of the dinosaurs.

The asteroid could also have carried DNA, either naturally or even artificially, from another planet in the galaxy, to Earth.

 

[Santaman]

Nope, that thing hit with the force of several hydrogen nukes, NOTHING survived that, totally vaporized anything remotely organic.

 

['Q']

Yes, the answer is Earth.

 

[MacLeod]

Wait, what the asteriod could have carried life from another planet in the galaxy? I guess this supposed ex planet was hit by something which caused a chuck of it to explode off with surviving life and sent on a trajectory that woud bring it the Sol System which would result in an impact with the Earth, and not say Jupiter which has a far stronger gravitational pull than the Earth.

So which solar system did this asteriod come from?
How long was it travelling in the interstellar void?

Sounds rather far fetched to me.

Their ancestors have been around for, at least, 66 million years.

Isn't that how panspermia works?

Not sure that is how it works with a six mile asteroid. The resulting explosion would not be good for any living thing in the general area.

Here is my idea:

---vorticity

The smokers on the sea floor are like alembics of the deep...nature as Hermes Trismegistus

Remember this?

So let’s say you wanted to make detergent. Let’s say you’re Unilever and you want to make detergent in a factory near Liverpool. How do you do it? Well you have this great big tank full of liquid detergent. You pump it at a high pressure through a nozzle. You create a spray of detergent. Then the spray dries. It turns into powder. It falls to the floor. You scoop it up. You put it in cardboard boxes. You sell it at a supermarket. You make lots of money.

How do you design that nozzle? It turns out to be very important. Now if you ascribe to the God complex, what you do is you find yourself a little God. You find yourself a mathematician; you find yourself a physicist — somebody who understands the dynamics of this fluid. And he will, or she will, calculate the optimal design of the nozzle. Now Unilever did this and it didn’t work — too complicated. Even this problem, too complicated.

But the geneticist Professor Steve Jones describes how Unilever actually did solve this problem — trial and error, variation and selection. You take a nozzle and you create 10 random variations on the nozzle. You try out all 10, you keep the one that works best. You create 10 variations on that one. You try out all 10. You keep the one that works best. You try out 10 variations on that one. You see how this works, right.

And after 45 generations, you have this incredible nozzle. It looks a bit like a chess piece — functions absolutely brilliantly. We have no idea why it works, no idea at all.

Earth was hotter...the Moon closer...the tides rougher. Instead of nozzles, you had smokers with water shedding vortices:

Now I remember a MN tornado on videotape...that had a double helix shape to suction vortices.

DNA gets cooked and spun up..unilever style. That's my guess.

Yeah, evolutionary algorithms manifested in hardware rather than software. It's been tried lots of times. You can use such algorithms to come up with electronic circuits that apparently function but no-one is sure why - they appear to work by exploiting nonlinear interactions between the components that are difficult to model.

Hell planet to get life going in a cosmic shooting gallery. Life gets more complex as the planet calms down.

That might mean a water world, even with an oxygen atmosphere via chemical means…could be quite sterile. Too perfect to get anything cooking. You land on it…it’s all yours. It can’t contaminate you or you hurt it. Perfect.

The solution to the Fermi paradox is simply this:

Earth is the most violent place in the whole damn universe. Always has been. That’s why we are here. We are the spawn of cosmic violence…of the whirlwind, and the whirlpool.

 

[Dryson]

Earth was a ninth level of Hell planet at one time. Nothing proverbial, similar to the surface of the Sun.

Life could not have been held in any stasis on Earth during the Hell time of Earth due to extreme heat, lack of pressure and gravity. This means that life had to come from a different source other than being part of the original mixture of Earth. A source where life had already developed based on the same or nearly the same pressure and gravitational influences that existed on Earth after the Earth cooled, more importantly the water cooled to a point of allowing life to flourish.

Therefore the mixture of chemicals and other compounds critical for life to take hold on a planet, came from some other location in the galaxy.

If I have a boiling and burning pot of water on a stove and toss in some fry what happens? The fry die and become unusable compounds and base elements.

But, if the boiling and burning water cools and the same fry are tossed in what happens?

The fry survive and feed on each other and other fry along with very small life and reproduce.

Life had to have come from an asteroid similar to the dino killer roid.
