@Kasz: Absolutely, it is still just a hypothesis, but even the fact that you have something as strange as organelles in a bacteria that have their own set of DNA almost intuitively suggests that they were once their own separate bacteria. I have yet to see an explanation that makes as much sense given the nature of mitochondria/chloroplasts and bacteria themselves.

I believe in Evolution... so just playing devils advocate but...

What about helpful DNA Damage?

Rather then like with humans where it is negative... the DNA damage actually helped those parts of the bacteria... and as such the DNA damage was helpful?


After all Cancer Cells are genetically different from other cells.  If we were born with cancer one could come to the same conclusion you did?

Additionally there are people with two types of DNA.

Some are due to inheriting their wayward twins DNA and others happen due to errors in replication.

It could of just been the cause of a replication error.

That is also possible, although I still think endosymbiont hypothesis makes more sense considering the number of plasma membranes surrounding those cells which suggests that they were absorbed or ingested through a phospholipid bilayer.  It is highly unlikely that the DNA damage hypothesis would produce that result.  Not to mention that we have found an organism that exists (or at least existed) that is incredibly similar to a chloroplast, the cyanobacteria. 

The A and C illustrations in this picture don't directly mention what I am talking about with the phospholipid bilayers, but visually that is what I am talking about:

 

 



We had two bags of grass, seventy-five pellets of mescaline, five sheets of high-powered blotter acid, a salt shaker half full of cocaine, a whole galaxy of multi-colored uppers, downers, screamers, laughers…Also a quart of tequila, a quart of rum, a case of beer, a pint of raw ether and two dozen amyls.  The only thing that really worried me was the ether.  There is nothing in the world more helpless and irresponsible and depraved than a man in the depths of an ether binge. –Raoul Duke

It is hard to shed anything but crocodile tears over White House speechwriter Patrick Buchanan's tragic analysis of the Nixon debacle. "It's like Sisyphus," he said. "We rolled the rock all the way up the mountain...and it rolled right back down on us...."  Neither Sisyphus nor the commander of the Light Brigade nor Pat Buchanan had the time or any real inclination to question what they were doing...a martyr, to the bitter end, to a "flawed" cause and a narrow, atavistic concept of conservative politics that has done more damage to itself and the country in less than six years than its liberal enemies could have done in two or three decades. -Hunter S.
