Not true. As a species spreads, environmental factors have a large impact on how they adapt over time to the point where you get a different species. Over a long period of time, a predator may not even be a predator any more because of a lack of the food it considers normal. You get different species with a common ancestor.

True, but saying that every species has the same, single ancestor doesn't make sense. We're basically back at a 21st century equivalent of "God".
How do you know so much about swallows? Well, you have to know these things when you're a king, you know.

Actually it CAN make sense. It is a possibility. "Likeliness" is not a concern. What is important is finding all possibilities for the origin of life and eliminating or advancing them with evidence and experimentation.
Possibility 1) Everything descended from a single original organism.
Possibility 2) There may have been multiple original organisms in various parts of the world, eventually meeting up and creating new species.
Possibility 3) Life originated somewhere else and was deposited here by an impactor of some kind, be it dust, comet, or asteroid.
Possibility 4) Any combination of the above.

Homo sapiens origins appear to be in a single place. Hominids however not so much. Besides, the expansion potential for homo sapiens was, I would venture to suggest, rather greater than strands of DNA that hadn't yet figured out how to make a cell!

Considering how unlikely the life-creating event is, even when all the right stuff is in the right place, a single-event is probable. Once established, it can spread as it mutates into endless diversity.
That being said, time has been around a long time - so other events may have occurred and if they compete for resources then only one version may survive - either because it's more efficient, or very likely because it got there first.

That's the real question right there: how easy or difficult is it for life to get started?
If it's very difficult, then the single event is likely. If it's easy, then the single event is unlikely.
Personally, I'd be very surprised if our own solar system isn't full of life.

And for that, time is on your side (at least five billion years worth of it, so far).

It is. It's just all on one planet!

Is our planet the whole solar system?

 If a pond is full of fish and I then herd all the fish into one corner of that pond is the pond no longer full of fish? Is there not an abundance of fish in the pond irrespective of where they happen to be? Is there no possibility of a superfluity of fish as long as there is some part of the water in which there is no fish? Has the word 'full' suddenly acquired a meaning requiring even distribution or it doesn't count?

Sorry if I've confused you. I'd thought my original statement "if our own solar system isn't full of life.." was actually pretty clear.
However, let me clarify that by saying "our own solar system", I was referring to every planet, moon and lump of rock between the sun and the farthest edge of our solar system[^].
I can't say it any clearer than that. If it's still not clear, then I'm not really the guy who can help you.

The Earth is only a part of the solar system, it's not the whole solar system.
I really shouldn't need to explain this, should I?
Do I explicitly need to exclude Earth? If so, consider it excluded.

What was the point? Wordplay, that's all.
Someone looking to ignore the point I originally made with (what they thought would be) a clever comment.
Great, thanks for that. This is why nothing gets done these days, we all just sit around making smart-arsed comments that contribute nothing.
Well done, keep up the good work.

Dunno, I expected a normal conversation..
If I'd have wanted replies along the lines of "you're, not your" I'd have commented on the Guardian.
Oh well, that'll teach me.

Take a look at the original reply[^] - where's the humour?
You seem to be someone out looking for anything to argue about. I made a comment about life probably being spread across the solar system, got a reply saying it's all here on earth, I re-stated that I meant the whole solar system.
What's your issue here?

Kind of stating the obvious.. why would restaurant patrons be in the kitchen? Maybe it's an American thing that I'm missing here?

Probably. So what of it? We're all different aren't we?

I'm sorry, I just don't see the humour. Maybe it's me?
Xaotiq wrote: On that note, then isn't it obvious what he said? Or do you expect there to be life floating in the middle of space between Earth and Mars?
He said it's all here on Earth. Yes, obvious what he said. No, can't see the humour there. If I was to take things further, it sounds like what a midwest bible basher might say. I'm jumping to conclusions here.
