It seems like a peculiar case of genomic overkill: a single-celled bacterium has been found that keeps tens of thousands of copies of its genome. The finding sets a record for most genomes per cell, but also poses an obvious question: what could be the advantage of stashing away as much as 200,000 copies of your genome?
The number of genome copies in each cell varies by species. Many bacteria have only one copy; most cells in the human body contain two. Plants are notorious for being genomically promiscuous, picking up extra genomes then losing them again in a cycle that can occur repeatedly in a plant's evolutionary history. "You may think that as a blueprint of life, the genome might be very stable in size," says Sally Otto, an evolutionary biologist at the University of British Columbia in Vancouver, Canada. "So it is really quite remarkable that organisms vary so widely in the number of genome copies they have."

It’a a mainstream Republican.....no aim, no goal, incapable of shedding of excess baggage.
That part fits too, which is why I included it, it was just that the other was first on my list.
I grew up on a farm, farmed for many years and learned to take satisfaction when I’ve done a good job.
Can’t speak for all of Asia, but I enjoyed the few days I spent in Kao-hsiung.
My dad mostly liked the times he spent in Asia, except for those times when the Japanese, Koreans/Commie Chinese and Vietnamese were trying to kill him...
I agree.
I don't think my dad enjoyed the Phillipines (WWII), Korea or Vietnam, for various reaons. All different. While he didn't actually fight in Korea, he served there (cold!). There aren't many like him left.
No, not many. When last I heard only about 13,000 surviving vets of those three wars.
The most prized gift I ever got him was a cap that says “Veteran WWII-Korea-Vietnam”.
It is a real door and conversation opener. He loves it.
Yeah, our 'troubles' are just selfish crybaby stuff compared to fighting and surviving 3 wars.
They truly are the greatest generation.
So far. I still hold out some hope for our kids. Many of them don’t have quite the sense of entitlement the hippy generation has. Nor the illusion that we can love our enemies into loving us.
Isn't it funny how often the children reject the values of their parents?
I'm so conservative my kids may turn out to be flaming liberals! Yikes.
LOL! That’s where I have a HUGH and SERIES advantage over you.
The ex is a flaming liberal....

My aunt was the same way. I just thought she was senile. Maybe it was a product of living through some REALLY hard times.
Maybe that has the original blueprint was written by the Architect?
My unstudied guess is that they are used when the bacteria wants to rapidly reproduce and form many copies of itself.
