Version 1.3 August 2015Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â (Previous
Version)
These are the questions we ask in the introduction (Section 0.1.6 –
paragraph 10):
If god did not create life, where did it come from? How
can all the complex processes required for just a single living cell come
together all at once? isn't it like a storm in a junkyard producing a jumbo
jet? Aren’t the chances of life so miniscule that is has to be a miracle? How
can dead matter suddenly come to life? What is life anyway?
We may refine these as we develop this Chapter.
This chapter covers chemistry and biochemistry, in just
enough detail so that we can work out what to believe and why, so that we can
decide what to do, in our day to day life, and in the big decisions of life.
We plan to look at how we know what we know under the following
topic headings. For now, we have indicated below the questions we intend to
address and the main topics we intend to cover.
|
1. Simple Molecules:
|
How do molecules combine from
the elements in the early earth?
|
|
2. Organic Molecules:
|
What are the basic organic
compounds?
|
Is it
reasonable to break down this area into these topics at this level?
Click on
feedback, or add a comment below, to tell us if you agree or disagree, or
suggest improvements.
|
|
3. Complex Molecules:
|
What are purines and
pyrimidines?
|
|
4. Chain Molecules:
|
How did the building blocks of
life form?
|
|
5. Possible RNA World:
|
What might the first life have
been like?
|
|
6. Current DNA World:
|
What is the basic structure of
life now?
|
|
7. Photosynthesis:
|
How do plants get their energy?
|
|
8. Respiration:
|
How do animals get their
energy?
|
|
|
9. Metabolism:
|
How do simple cells function?
|
|
|
10. Reproduction:
|
Is sex the only way to
reproduce?
|
|
|
11. Eukaryotes:
|
How did we get the complex
cells we see today?
|
|
|
12. Life Affects the Earth:
|
Where did our atmospheric
oxygen come from?
|
|
|
|
|
|
This is the current summary of our conclusions in this
area:
Science is working out how life began: how simple
chemical processes formed local cycles, copies of these formed, other molecules
enclosed these processes to form living cells; how photosynthesis
began (which made atmospheric oxygen), respiration captured energy for the
cells, and how cells became more complex.

The detailed sections explain how we
justify these conclusions.

Do you know of any great music that would go well with this
page?
Or any of the other pages?
IF
YOU DO, CLICK FEEDBACK.
It could be in any language, or have no words, or just be
instrumental. From pop, to classical, a cappella to orchestral!
Examples of the
music we seek:
● On
the Tenets page, accessed from the main menu, our current choice is a Song
Without Words from Mendelssohn (who died in 1847), Opus 14 Nbr 4, called Contentment. Check it out: the Tenets
conclude most
times, I have a measure of content.
● Chapter 2.3 covers the solar system
and Earth’s development. In there somewhere, surely we should be
hearing Gustav
Holst's The Planets, which premiered 100 years ago. There is a movement for
each of the planets.
Please tell as
much identifying information as you can: a link, and/or the name of the piece
and a person’s name may be enough, but if you know it please also send
the artist/performer, composer/lyricist, year written, year recorded, record
label, copyright owner, or similar details.
We have to worry
about copyright: acknowledge it, and not infringe on it. Music that is
out of copyright, or was never copyrighted (eg like real, ie very old, folk
music) is good. Some material is ‘open source’ allowing others
to use it for free. For newer restricted copyright music we may have to
seek permission to play it, but we can’t afford to pay for it. It
depends on the circumstances. In general, copyright in text, images and music lasts
for 70 years after the year of the creator's death, even if the creator does
not own copyright.
