Two Problems with most Origin of Life Scenarios

April 8, 2018

Two problems with most origin of life scenarios:

1. Life magically pops up completely formed.

2. Life magically survives a hostile environment without any evolved protection.

Holding Genes Passes Genes

December 8, 2017

Holding Genes, Passes Genes!

This article, “Holding Infants – or not – can leave traces on their genes,” supports an idea I’ve had called “Carrying the Baby.”

My sci-fi novel, “Writings in Science a History of the Future” suggests that a key reason for the development of humans brains are ‘carrying the baby.”

First humans (hominids) walked upright. This led to their hands free – not only for war (most scientists are men) – but for carrying the baby.

This led to a stronger mother child bond, that I suggest supported everything from language development, to human intelligence.

Read the article, then read my sci-fi novel, perhaps the biggest ever written. Now available at all major streaming book sites.

Musea Quizzical 12/17

December 6, 2017

The answer to, and winner (if any) for, our last contest question of:

What is this … ?

IS …

An ellipsis! Three dots ( … ) that suggest continuation, are called an ellipsis! So easy! I had no correct eligible answers. Seems we had a case of un- punctuated equilibrium … in the brain! I don’t dumb down so please wise up.

Now on to a new Q.: Win a copy of any of my 9 CDs, a streaming copy of one of my 6 books, or copy of one of my artworks, IF you are the first to …

E-MAIL ME AT THIS ADDRESS: tom-hendricks @ att.net (remove blanks of course) with the correct answer to the following art question .

DEDICATION: These contests are dedicated to my sister, Peggy, who answered more of the questions correctly than anyone else so far.

QUESTION

Sexual harassment is certainly nothing new. This major female actress, wrote this about working at her classic TV series:

“That show catered to every kinky thing imaginable – and no wonder considering some of the writers we had. We had a foot fetishist I’ll never forget. That’s why I was always being photographed in leather boots with my feet stuck in the air somehow. Another one was fascinated by bondage, so for another string of shows I was always getting tied up in some outlandish way. And the leather! God, I thought I’d never get out of all that leather. ”

Name the actress. (Then stop sexual harassment!)

FINE PRINT: The prize is only available to those with mailing addresses in the US. Foreign winners will have to settle for the miniscule fame alone, and the satisfaction of a job well done. But don’t forget you can always listen to all the music , read all my writings, and see all the art, whether you win or lose – and I’d be glad if you did!

Readers, IF you like these puzzles and would like to resend them to friends, post them on any newsgroup, or any website, please do so. The more the merrier!

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?

Musea Quiz 10/17

October 24, 2017

The answer to, and winner (if any) for, our last contest question of:

I say Earthlings have landed on Mars. You say no.
When I tell you why I know that it is true, you will say … Yes Tom you are correct and I was wrong. Explain what is going on!

IS …
Bacteria are Earthlings just as much as you and me. Though NASA does everything it can to keep the outer space hardware sterile, I doubt they cover EVERY bacterial Earthling. So I say, recently, Earthlings have landed on Saturn – and in all likelihood when the spacecraft Cassini fell into Saturn 9/15/17, there were bacteria aboard and they went down with the ship!

I had no correct eligible answers. Seems you didn’t have a GERM of an idea on this one. I don’t dumb down so please wise up.
