Long Term Evolution Experiment

The long-term evolution experiment is one of the most interesting studies done on the feasibility of evolution to produce complicated metabolic systems and new systems of information within cells. Evolution holds that mutations occur through natural processes which by chance produce advantageous changes.  These changes enhance the organism’s ability to survive and thus over time become dominant within the population. The problem with trying to substantiate evolution is that these changes take considerable time to accumulate within a population and show a survival benefit. Since people reproduce every 25 years, the time required to see inherited beneficial mutations accumulate with… Read More »

Willful Blindness

RNA and DNA are very similar in structure although they perform different functions in the cell.

Willful Blindness Preconceived notions can prevent otherwise intelligent and discerning people from observing the obvious. The editor of an obscure journal Proceedings of the Biological Society of Washington decided to publish a paper making the case for intelligent design.  Intelligent design is a controversial theory that suggests that life is too complex to have been self-assembled by accident.  Instead – as with all extremely complex machines that perform a function – it was put together by an intelligent designer. The Smithsonian Institute helps to fund and run this journal, and within hours voiced its intense displeasure that any favor would… Read More »

Finding Junk DNA in your DNA Watson and Crick discovered the chemical structure of the DNA molecule.  These brilliant scientists were able to determine the structure consisted of two complementary strands wrapped around each other, with one strand going in one direction while the other strand went in the other direction. Each of these strands was composed of subunits called “nucleotides,” each strand containing a sugar molecule (deoxyribose in the case of DNA) attached to a phosphate group and one of four bases: adenine, thymine, cytosine, or guanine. The Code for Life DNA is really an immensely complicated code for… Read More »

Information

The Earth seems to have been designed for exploration of the cosmos with its clear atmosphere, position in the solar system and universe, and clear nights.

Information and Life All life on earth is made from organic molecules. An organic compound is any chemical compound containing carbon-hydrogen bonds.  The propensity for carbon to form chains and complex structures means there are millions of organic molecules possible. Only a minuscule portion of the possible organic molecules possible are used in all life; these are referred to a life organic molecules.  Examples of these would be glucose or simple sugar, and proteins which are chains of other organic molecules called amino acids. Biology textbooks frequently suggest that given enough time under the right condition, the right organic molecules… Read More »

Prebiotic Soup

The prebiotic soup is thought to have come from comets and meteors over millions of years.

The prebiotic soup is the mixture of chemicals in the ancient Earth which produced the first life. It is commonly known throughout our culture, so much so that it was a theme of a Star Trek episode. In this episode, Captain Picard is taken back to ancient Earth to witness the prebiotic soup from which all life came. Generations of high school students have been taught the prebiotic soup is the organic chemical mixture of common chemical. Energy in the form of light and heat produce chemical reactions in the soup that with enough time produced the earliest life form…. Read More »

Origin of Life Molecules

Origin of life molecules can not be explained using natural science.

Origin of life molecules are those molecules that are required for even the simplest life.  They may form part of the structure of proteins (such as amino acids), or of DNA or RNA (such as the sugar ribose). The start of these origin of life molecules has never been explained. These molecules are formed in too low concentrations or not formed at all in natural conditions. Some origin of life molecules needs to be entirely of either the right or left-handed variety. One of the factors needed to make the molecular machinery work correctly is the right kind of molecules… Read More »

Bad Design Features Evolutionary scientists have had a field day with what are supposed to be “bad design features” of the human body.  These scientists bring up several design features which seem to work against the purpose of the organ system involved. The late Stephen Gould presented examples of what he considered “bad design” as an argument against a creator.  The best-known example was that of the panda’s thumb which he described as being clumsy. Another classical example of allegedly poor design is the human retina which seems to be inverted with the light-sensing cells behind a membrane.  This means… Read More »

It is very likely that life will be discovered on some other solar system body even though a naturalistic origin of life seems to be quite impossible. Life on earth has been very abundant on Earth for about 3.8 billion years.  We have some form of life everywhere; down to the very depths of the oceans, underneath ice caps, in deserts, and deep into the earth.  There is life from intense freezing cold to near boiling water near ocean vents. As said in Jurassic Park – life finds a way. When life does get discovered on another solar system object… Read More »
