Default Re: Is panspermia a scienctific theory?

So are you comparing the selective breeding of animals guided by a knowledgable and INTENTIONAL individual with Evolution?

Well, I didn't understand what you're looking for. But I am comparing them. There's a lot of nice analogies there. Evolution is change in the genetic composition of a population during successive generations. This is due to selection acting on the genetic variation among individuals. (and can result in the development of new species - not in many of these examples of course).

Let me be more clear: Has any scientist ever succeeded in taking a population of single-celled organisms, exposing them to some agent which causes mutations and created a population of something different than what they started with which retained these differences over at least two generations?

You do realize that speciation often takes a pretty long time don't you? So, no, in the few decades people have really been actively looking at this scientists have not been able to recreate the tens of thousands, hundred of thousands, or millions of years speciation normally takes.
And causing mutations is only one point of evolution, and that point is that they occur naturally so that's not really a hurdle. Most mutations are harmful.
But to get back to your single cell quesiton, how would you explain the development of bacteria resistant to antibiotics? Population of organisms exposed to a selection pressure and eventually you get a population very different form what they started with (not dying because of the antibiotics)

What about it? This stuff looks alot like that stuff but is different in certain ways; So this stuff must have come from that stuff -- still not proof, conjecture.

[/ QUOTE ]

A little more math though. How educated are you on this stuff that you can make those claims?

[ QUOTE ]
Please describe how ET would be falsified? How could one prove evolution doesn't or hasn't happened?

[/ QUOTE ]

Several of us have posted the "fossil rabbit in the precambrian" example.

A scientific theory needs to allow verification by providing predictive capability, and thus allows itself to be tested. How does ET do this?

[/ QUOTE ]

As one of the respected posters pointed out in another, similar thread, it doesn't neccessarily need to predict, it needs to explain.
