Two Clues to the Origin of Life

November 17, 2017

Two big CLUES to how life began on Earth.

1. There had to be continual energy.

Because of the energetic continuity requirement – which follows from the Darwinian evolutionary continuity principle (see Lahav (1999); Wolf and Koonin
(2007) and references therein) – the energy flows that deserve attention in evolu-
tionary context are those that remain constant on the evolutionary relevant, geolog-
ical timescale. This consideration essentially discounts the evolutionary importance of occasional energy inputs from impact bombardment, atmospheric electric
discharges, shock waves, volcanic explosions, and so on. It is also unlikely that life could notably depend on the chemical compounds that were produced or delivered during such occasional events. It seems implausible that the first life
forms could wait from one occasional event (e.g., volcanic explosion) to another to get energy and nourishment. There are no known organisms that obligatorily depend on such irregular sources of energy and matter.

2. Bases and UV.

The exclusive feature of natural
nucleobases is their unique photostability (Cadet and Vigny 1990). Since this trait is not related to the storage of genetic information, several authors (Skulachev 1969; Sagan 1973; Cadet and Vigny 1990) have noted that this property could have
been of some use when the UV flux at the surface of primordial Earth – owing to the absence of the ozone layer – was much stronger than it is now. Nucleobases apparently can absorb excess energy quanta from sugar-phosphate moieties and protect them from photo-dissociation (Goossen and Kloosterboer 1978). This feature explains why the UV damage to the backbones even of modern RNA and DNA molecules is 103–104 times less frequent than the destruction of nucleobases proper (Cadet and Vigny 1990). Under the assumption that the unique photostability of nucleobases could hardly be incidental, we have argued that
natural nucleotides should have been selected within the reach of solar light and that nucleobases may have protected the first RNA-like polymers from photo- dissociation (Mulkidjanian et al. 2003).

Both quotes from Mulkidhanian papers.

My suggestion is that life is the most stable chemical system under daily UV radiation. The problem with most origin of life scenarios is that there is nothing forcing the change except fate or fluke events. That problem is solved when the origin of live is a response to a daily cycle of UV. Then chemical systems have to change and adopt or they are destroyed.

Which is more probable, a one time pop up of 5 or so linked chemical steps that each have to occur in the proper order in a hostile environment that they are not protected in and that would quickly destroy each step, OR a chemical selection over millions of years of UV radiation?

Biological Basis to Fear and Anger?

October 23, 2017

Finally, after studying the problem over many many years, I may have some discoveries about where Fear and Anger came from.

SUGGESTION, the two key emotions of FEAR and ANGER have a very specific biological basis.

Both emotions have evolved out of key parts of the digestive system in all living things. The two are tied to taking in nurturing while protecting against infection.

FEAR is the body’s response to any infection.
FEAR helps us BLOCK OUT and EXCRETE OUT infection.

ANGER is the body’s response to hunger.
ANGER helps us TAKE IN and HOLD IN nurturing.

We are AFRAID when we think there may be infection.
We are ANGRY when we are hungry.

FEAR seems to be most active around the mouth and nose before eating.

ANGER seems to be the most active in the small intestines when taking in nurturing.

SUGGESTION, most of these digestive emotions of fear and anger, happened in infancy when we were setting up our body’s digestive system and defense system. That was the time of the most danger. That was also the time of the most emotions of fear and anger.

SUGGESTION, because the digestive problems of infancy were unconscious developments, and because they were the most intense periods of infection fear and nurturing anger; they may lead us to unconscious adult problems of excess fear, or excess anger.

This leads to all the autoimmune diseases and negative behavior connected with this excess, repressed, infant, fear and anger.

There is much much more to this, and more implications than I can fathom right now.

Volcanic Moon and Bombardment Phase

October 20, 2017

Saw this about the Moon having a thin atmosphere 3.5 to 4 bya.

https://www.sciencedaily.com/releases/2017/10/171009091908.htm

I always wondered why the half of the moon facing earth was so cratered while the other side was not.

Could it be that this volcanic outgassing was pulled out of the Moon by the gravity of the Earth?

Then, if that is true, does that suggest that the bombardment, was not asteroids as much as it was the Earth forcing volcanic activity from the near side of the Moon?

Then, if there was not the severe bombardment phase, we can move back the OOL (origin of life) to an earlier time?

Biology – The Danger Of Over Washing

Suggestion – the over washing or over medication of our bodies harms or destroys our microbiome, the good bacteria that protests us from diseases.
