Evolution is a Theory and a Fact, with Laurence Moran part1

WTF!??!
Is this the first time ever they do this?
Can't somebody edit out the first 4 minutes?

When precisely is "not far from now"?
Are we talking a few weeks? This summer? 2009? Etc...?

What type of eruption are we talking about? Hawaii type? Mt St Helens? Extinction level event for the middle of the country?

Without details, your "prediction" is quite vague and meaningless...

All these thing can change with generations...

No question, you truly believe 4600 million years ago the earth was a ball of molten lava, 700 million years later after torrential rains a prebiotic soup was produced and out of this soup miraculously emerged the first living organism whatever it was, and then on an everchanging world this first organism diverged into the whole diversity of life living and extinct...you´re right: There´re no restrictions to hallucinate.

Just wondering though..

Do you think or believe that the process i described "can" happen ( having ended up where we are now, indifferent of whether it was the correct explanation of the past ) using the principles i described? ( that would be: increase in dna though duplication, breaking of strands into chromosomes, and mutation over time )

if yes, what restricts you from extrapolating these findings,
if no, what findings appear to be missing to you?

MSH1044

First at all, chromosomes number range from 2 (ant) to 1260 (fern) there´s no correlation in any sense an ancestry organism whate ever it was diverging into the whole diversity of life...
First unsurmountable question is:
How many chromosomes did it have?
Is dna insertions/deletions and duplication enough to explain how the diversity of life came into being?
What is the outcome of an dna insertion deletion or duplication?
Is cancer the outcome of a mutation?

msh1044

If yes, what restricts you fromextrapolating...

Yes, but the question would be:
What are the real outcome of such phenomenon observed at the molecular level?
When cells makes not exacly the right copy most of the time we have "cancer" not a better organism...

I never expressed an oppinion about any of these things, neither is it really relevant to the discussion we are having. The relevent part of my post was the observation that their does not appear to be a restriction at the cell level as to what can change towards what.

DNA is urely a very long molecule, but it´s a repetition...

Surely it´s, that´s why expertise know-how in biochemestry can make copies very easily, it takes a while but it´s very easy, no doubt...keep on dreaming

well, i don't recall "know-how in biochemestry" in my previous post. but cells themselves copy the entire dna strand often in far less then an hour. In one human life time around 10,000 trillion cell divisions occur. so its not terribly hard for live forms to make a copy of a dna strand. and with these amounts of copies being it's not hard to come up with the idea that some will not be copied exactly right. (and this is exactly what we observe, dna insertions/deletions and duplications)
