Why Life Begins At Conception, Part 1


Over the next few days I will be posting, in several parts, on the subject, Why Life Begins at Conception.  The posts may not be on consecutive days but they will make the most sense to you if they are read in consecutive order. 

The subject has become a very hot topic in the United States because of the poorly thought out comments (I would say something more harsh except for the nature of this blog) of one of the current United States Representatives. 

The current controversy concerns abortion and certain types of contraception and the timing of when a developing fetus becomes “human.”  Does life begin at conception or sometime later in the pregnancy? Does the developing fetus have legal rights as a person?

The question is presented by many as a religious question, and it is, but a rational and scientific case can be made for opposition to abortion without any reference to religion.  Many people will not listen to a religious argument, but they might listen to a scientific one.

The posts in this series will present, in a highly simplified way, the scientific information necessary for a case against abortion and some forms of birth control.  Also, the very strong emotions of persons on both sides of the issue will be discussed.

1.     This is not, never has been, and never will be, a political blog.
2.     I am qualified to present this particular scientific information because my undergraduate degree is in biology with a concentration in developmental genetics and embryology.

Film Comment: Splice

"She's not human ... not entirely."  This is the tagline for the truly disturbing 2009 Canadian science fiction film, Splice , starring Academy Award winner (2002) Adrien Brody, Canadian actress Sarah Polley, and French actress Delphine Chaneac in the role as the adult creature/specimen/thing/woman.  When I saw this film , I heard someone say that they felt like they needed a bath upon leaving the theater. It is that intense, bizarre, and perverse.

A male-female genetic research team (Brody and Polley) at the Nucleic Exchange Research and Development laboratory (N.E.R.D.) are working on creating hybrid animals (mixing genetic material from several species) for medical use.  When their funding is threatened they rush to accelerate their results and secretly add human DNA (their own) to the mix.  A viable little bird-like thing results.  They name it Dren (N.E.R.D. spelled backwards) because the female researcher almost immediately takes a mothering attitude toward the creature and insists that it is not a "specimen."

Dren cannot speak, after all, she is an animal; she coos like a bird.  She proves to be inquisitive, intelligent, graceful, and she grows at an alarming rate.  She is an adult within days.  She is tall and slender with a beautifully innocent face, her knees bend backward instead of forward, her feet resemble hands, and she has a long prehensile tail tipped with a poisonous stinger.

As she matures, Dren becomes very noticeably female and increasingly seductive. "Poppa" makes the mistake of spending time alone with her and willingly/unwillingly ends up as the object of her intense attention.  Then his wife catches them.  He is having sex with his "daughter," he is having sex with an animal, he is having sex with himself.  Dren is all three.

This film touches on the subjects of cloning, responsibility toward our offspring, aberrant sexuality, intense self pride, and amoral scientific research just for the "science."  It is, in reality, a variant on the Frankenstein theme.

The most disturbing thing about this film is that it is on the edge of no longer being science fiction.  Much of science fiction eventually becomes science fact.  Jules Verne wrote of space travel and submarines; now they are established fact.  On the first Star Trek television series, the characters would reach into their pockets and pull out their personal communicators; we now call them cell phones.

Modern molecular biology can already insert DNA sequences into bacteria and cause them to produce synthetic chemicals they would normally not produce.  The entire human genome has now been deciphered with the prospect of the ability to insert healthy DNA sequences in place of faulty ones.  The mutant genetic sequence which causes the bacterium Staphylococcus aureus to be resistant to methicillin (MRSA) can be detected in one hour from a nasal swab.

Artificial life may be just around the corner.  It may already be here.  In 2010, Dr. John Craig Venter of Utah, USA announced the creation of an artificial bacterium using synthetic DNA.  His research is aimed at producing modified microorganisms which can produce clean fuels and biochemicals.

Christians believe that God is the Creator.  There are so many questions. What will it mean if man also is a creator?  What will God think of our glorification of the human intellect?  Does God intend for us to learn all things?   Are there things we should not learn?  Are there things we should not do even if they are possible? Do scientists bear any responsibility for their discoveries?  What if our science creates a Dren?
