A mutation had occurred that conferred no advantage the bacterium but it primed it to take advantage of a later mutation
Fascinating. That explains a great deal. This is very helpful, I'm finding the details of evolution starting to drop into place.

Evolution is a Fact #12 - Lenski's E. coli Experiment
by cofty inevolution works by the non-random selection of random mutation.
natural selection accumulates favourable random chance events.. the experiment that was began on 24th february 1988 on e coli bacteria by dr richard e. lenski and his team is surely one of the clearest demonstrations of the power of this process.. e.coli is one of the commonest bacterium on earth, there is around 100 billion, billion of them in the world at any given time and around 1 billion of them in your gut right now.
most of the time they cause no problem, until a new strain wreaks havoc on its host's digestive system.. if we assume the probability of a particular gene mutating to be 1 in a billion, the size of the population is so high that just about every gene in the e.coli genome will have mutated somewhere in the world every day.

Why it's a waste of time talking to JW's
by Phizzy ini believe it to be a waste of time talking to, reasoning with, jw's if you expect any kind of quick result.. many of us when we first wake up think that 'coz ttatt is blindingly obvious to us, it will soon get through to our jw loved ones.. this simply isn't so for a couple of important reasons.
the first is that, if someone believes something is true, or the truth, to them it really is, without doubt, true.
so whatever you say must be wrong somehow.. the second problem is that jw's simply do not have to use, or pay any attention to facts and logic.

It depends on the personality type I think. There are people in my extended family who say things like I don't do texting, I don't do ATMs, I don't buy things online it's not safe. My relatives seem very stubborn, emotional, paranoid and they hate change. So it's no surprise that the JWs among them want to snuggle down in their comfort zone and keep the status quo. Struggling against these people since childhood has profoundly affected the way I see others and I really have to fight the urge to give up on people because of my 'brick wall' relatives.
I don't think all families are like this Phizzy. Some people are more cerebral and they like to think, they enjoy reading and learning new things and while not relishing change can see the need for it. God knows why I am different from them but that's genetics for you. The genes fall differently every time. Apparently my maternal grandmother had a brother who went to sea and travelled the world. He was a real explorer and loved change. Now there was a relative I should have liked to have met.

Quite a few butterflies in the garden today. Red Admirals, small blues and Tortoiseshells. I saw my first Orange Tip last week. The bee balm, Monarda, isn't quite big enough to plant out yet but hopefully that will attract more insects. It does smell lovely which made the seedlings a real joy to pot on. Looking forward to the flowers. -

Half banana it's a very rosy eating apple, quite delicious. I don't know the name of it, it was here when we bought this house. I also have a cooker that tastes very similar to a Bramley which is just coming into flower. I will try and post a picture of it but it's very slow loading photos from my iPad on this site today.

Outstanding new book out today for you atheists, agnostics, humanists, naturalists and free thinkers
by Cornbread ini just got back from the bookstore and i can't wait to sink into it based on all the reviews and press it has been getting.
it's called the big picture - on the origin of life, meaning, and the universe itself by sean carroll.. “weaving the threads of astronomy, physics, chemistry, biology, and philosophy into a seamless narrative tapestry, sean carroll enthralls us with what we’ve figured out in the universe and humbles us with what we don’t yet understand.
yet in the end, it’s the meaning of it all that feeds your soul of curiosity.” —neil degrasse tyson, host of cosmos: a spacetime odyssey*publishers weekly #1 most anticipated science book of spring 2016*"already internationally acclaimed for his elegant, lucid writing on the most challenging notions in modern physics, sean carroll is emerging as one of the greatest humanist thinkers of his generation as he brings his extraordinary intellect to bear not only on higgs bosons and extra dimensions but now also on our deepest personal questions.

It is now official: Another falsified Watchtower prophecy
by ILoveTTATT2 in"jesus was obviously speaking about those who were old enough to witness with understanding what took place when the 'last days' began.
... even if we presume that youngsters 15 years of age would be perceptive enough to realize the import of what happened in 1914, it would still make the youngest of 'this generation' nearly 70 years old today.
" awake!

I mean, I am also not invited to paradise - should I be equally offended? Should I call the newspaper
I am offended that my relatives have been commanded to ignore me and then my child for nearly thirty years because they are afraid of being shut out of paradise. This vid is about being very careful not to do anything that will cause them to be shut out of paradise. Including admitting to one's sexual orientation.
I am not shocked by this vid, it is typical JW cultism but why should the world not comment on it? We should speak up against any form of discrimination. I am part of normal human society now and 'we' speak up against discrimination.
