Fundies Will Be Shitting Bricks

Some process in chemical evolution must account for the origin of homochirality, i.e. all building blocks in living organisms having the same "handedness" (amino acids being left-handed, nucleic acid sugars (ribose and deoxyribose) being right-handed, and chiral phosphoglycerides). Chiral molecules can be synthesized, but in the absence of a chiral source or a chiral catalyst, they are formed in a 50/50 mixture of both enantiomers. This is called a racemic mixture. Clark has suggested that homochirality may have started in space, as the studies of the amino acids on the Murchison meteorite showed L-alanine to be more than twice as frequent as its D form, and L-glutamic acid was more than 3 times prevalent than its D counterpart. It is suggested that polarised light has the power to destroy one enantiomer within the proto-planetary disk. Noyes[64] showed that beta decay caused the breakdown of D-leucine, in a racemic mixture, and that the presence of 14C, present in larger amounts in organic chemicals in the early Earth environment, could have been the cause. Robert M. Hazen reports upon experiments conducted in which various chiral crystal surfaces act as sites for possible concentration and assembly of chiral monomer units into macromolecules.[65] Once established, chirality would be selected for.[66] Work with organic compounds found on meteorites tends to suggest that chirality is a characteristic of abiogenic synthesis, as amino acids show a left-handed bias, whereas sugars show a predominantly right-handed bias.[67]

So are you conceding that abiogenesis could not have occurred on earth and you are just moving the story telling to outer space?

---

Furthermore, your claim that Fox's experiments used temperature conditions not found on Earth is, to put it rather bluntly, bullshit. Fox heated his apparatus to around 180 C. There are thermophiles deep within the Earth (about 3 km down) and in the vicinity of black smokers and other hydrothermal vents that can survive these temperatures.

---

Again, this is not what I argued. Do these vents all of the sudden cool in order to preserve the lifespan of the peptides like Fox did? I doubt it.

---

You also said "Never said the amino acids were not found in nature, I said their pure forms were not, the impure forms would not form peptides."

Using this logic, we should not even exist. If impure forms cannot form peptides, then that means that only pure forms can exist in the human body. Now, unless you are arguing that human beings don't exist in nature...

---

They exist inside living cells where they have a DNA/RNA system to help them form. So are you suggesting the first life on earth arose inside an already living cell? Let’s stick to the topic at hand, abiogenesis. Impure amino acids could never spontaneously form peptides outside of the cell which is what you seem to believe happened 3.5 billion years ago.

No, according to historic documents from the time, slaves were treated much worse. Yet Jesus knew about it and did nothing to discourage it, and in fact, left instructions on how they should be treated.

---

What historical documents? I get the impression you are being purposefully vague here.

---

There is no hiostorical evidence that anything in the Book of Exodus ever happened.

---

National Geographic had a series a couple years ago that showed plenty of historical evidence confirming the exodus. I think you are cherry picking your evidence.

---

And Statler, that you apparently believe that there is no basis for the moral conviction that slavery is wrong is all I need to know about you. So we have here a right wing evangelical Christian who believes in magic old men creating a universe POOF 10,000 years ago who also believes that slavery is morally justified. Wonders never cease to amaze.

---

I never said I don’t have a moral conviction against slavery now did I? I asked for yours, which is a request that has been ignored now twice. So I will just assume you have no logical basis to say slavery is wrong. Fair enough? If this is not fair, please give me one.
