Darwin and Corona Virus Vaccine

In addition to my teaching and tracking the corona virus numbers for Cambria County I have been reading the book that is currently tied for first place on my best nonfiction book pollOn the Origin of Species by Means of Natural Selection by Charles Darwin.  For me it is not as dry a read as Moby Dick.  It talks about how species of plants, animals and microorganisms change over time.  

The modifications that appear in organisms appear at random.  Most of these changes are detrimental.  Once in a while a modification to a member of a species gives it an advantage in survival over its rivals.  These traits will be selected for in the population in breeding.  

Viruses and bacteria, with simpler DNA sequences than multicellular organisms can mutate more easily and be modified faster.  I wonder how many who still don't believe in Darwin's theory also believe that the Corona Virus was created by a sinister scientist in Wuhan China.  How many of these are also hesitant to be vaccinated?  As the vaccine has become more available, the 7day average for new full vaccinations has been coming down from 891.1 per day on April 18 to 332.3 per day today.

Ambiguous Symbols in 2001:A Space Odyssey

When asked by the Mason’s to write about a symbol and it’s meaning, I chose one of the most enigmatic in cinematic history.  The film 2001: A Space Odyssey begins with a group of australopithecines in an African desert struggling to survive in finding food and battling with rival clans of their species.  Seemingly from out of nowhere a rectangular black monolith appears.  The australopithecines are confused by what they see.  Regardless of what they did see, after encountering the monolith they gained the capacity to use tools.  This made them better hunters and better able to fight off rivals.  This first part of the film is called The Dawn of Man as the australopithecines were the first primates to walk upright and are thought to be a link between chimpanzees and humans.

The film then leaves the earth as a US spaceship is flying towards the moon to investigate a strange sighting there at the US moon colony.  A cover story about an epidemic in the colony was created to keep the Soviets away.  When the people on the spaceship arrive at the strange sight we see that it is the same monolith that the australopithecines saw.  They discover that the monolith is sending radio signals to Jupiter.  In this segment, human’s use of tools has advanced greatly but groups of humans (represented by the US and the Soviets) are still in conflict with each other. 

After encountering the monolith on the moon, the US sends a top secret mission to Jupiter to investigate what it is sending radio signals to.  The spaceship is controlled by the ultimate human tool, the supercomputer HAL.  As the ship nears Jupiter, HAL malfunctions and kills all but one of the astronauts on board and lets the air out of the ship.  The lone survivor on the ship, played by Kier Dullea, has no choice but to investigate the monolith alone after disconnecting HAL. 

As Dullea approaches another monolith in orbit around Jupiter he has a psychedelic experience while being transported to a strange room where he ages rapidly.  As he approaches the end of his life he encounters the monolith and is then transformed into the star child floating above the Earth.  The ending is ambiguous and has had people debating it ever since.  When asked about the ending, the director Stanley Kubrick said “If you understood the ending, I failed.”

At every moment in the film where the monolith appears, the next step in human evolution is complete.  This seemingly inanimate object has the power to direct evolution.  The film 2010: The Year We Made Contact (without Kubrick as the director) addresses some of the ambiguities about what happened to Dullea’s character and why the computer HAL turned homicidal.  This time a joint US-Soviet mission returns to Jupiter and encounters HAL, Dullea and the monolith.  Exactly what the monolith is is not addressed to leave something to the imagination, and a possible sequel.  It could represent a supreme being, it could simply be a tool of a more advanced alien society to achieve some positive aim, or it could mean nothing at all.  This ambiguity is what makes the monolith so fascinating.

A New Science YouTube Channel

The website and YouTube channel Science Hive has been created to answer basic questions about science, especially about biology.  It's creator, Bee, is featured in the video above.  In it she gives a good definition of the difference between living and nonliving things.  In her next video whe gives a good explanation of mutations.

The Civil War in a Larger International Context: Darwinian Edition

This is the latest in a series of posts of earth shattering events which surrounded the US Civil War. They are tied either directly or indirectly to the war between the states.  The first two posts were on military conflicts which were concurrent with and were influenced by the battle between the Blue and the Grey.  These posts are listed in recent posts below.  

This post is about a scientific conflict which still has ramifications to this day.  Charles Darwin had exactly the same birthday as Abraham Lincoln, February 12, 1809.  Both men were considered ordinary until their ideas became well known in the late 1850's.  Both were very cautious about pursuing their proposals because they knew that they would encounter a lot of resistance.  An astrologer may attribute these similarities to their sign, Aquarius, while another explanation could also be coincidence.  

Naturally they did meet resistance when they pushed their ideas of abolishing slavery (Lincoln of course) and the evolution (Darwin's Origin of Species).  Of course these two men do not deserve all of the credit for these revolutions happening.  There were many abolitionists and scientists who worked tirelessly for years to lay the groundwork for a revolution in thought and action.  The abolitionists were aided by the industrial revolution which made slavery obsolete.  There is a whole field of philosophy on scientific revolutions on why and how they happen.

In the case of evolution there were discoveries in geology which showed that the earth must be far older than the Bible says (calculated to be about 6,000 years old) and that there were lots of mass extinctions of animals for which the Bible could not account.  Darwin's evidence he obtained on the voyage of the HMS Beagle and described in his book The origin of Species.  Journalist/Scientist James Burke does an interesting review of how Darwin's ideas were used to change society after The Origin of Species was published in 1859 in ways that he never intended.

While the scientific community and the powers that be accepted the outcomes of these revolutions.  A 2010 Virginia Commonwealth University survey of American's attitudes towards the life sciences still shows there is still considerable division on beliefs about Darwin's theories seen below in Italics.  I am not aware of any polls on regional differences on attitudes towards evolution but I would expect that where regions differ on attitudes towards the Civil War, attitudes are also most pronounced on evolution such as where the Scopes monkey trial occurred in Tennessee in 1925 or the Texas Board of Education Today.
