The Only Friend of the Groom

Author Erwin McMannus tells the story of a certain UPS driver named Dave whose days were characterized by what might be called "drive-by relationships". His tight delivery schedule meant that he had enough time for little more than pleasantries as he raced in and out of his customers' lives. But then there was Ron. Ron was a gas-station attendant who loved to talk. Whenever Dave's route took him anywhere nearby, Ron would find him and follow him in and out of his truck while he dealt with customers, talking non-stop until Dave would finally have to just drive away. Dave was a believer, but he dreaded the inevitable delays of running into Ron.

Then one day Ron handed him an envelope. It was an invitation. Ron was getting married, and he wanted Dave to attend. For the next three weeks, Dave avoided giving him an answer, until one day in a moment of weakness he told him that he would come. The big day arrived, and Dave was ushered in and seated on the left-hand side of the chapel as a "friend" of the groom. As it turned out, he was the only one. All the other guests took their places on the right side as friends of the bride. Only later did Dave learn that, of the 150 people Ron had invited, Dave was the only one who showed up. When it came time for offering toasts, Ron stepped up to the microphone, looked over at where Dave was seated, and said: "I'd like you all to meet my best friend, Dave."

Not surprisingly, God eventually used that relationship to bring Ron to faith in Jesus.

Car accident in Muslim Central Asia - Jesus answers prayer!

In the middle of the night a believer in a Central Asian country recently woke to a loud crash below her apartment. She rushed to the street to find four unresponsive young people in a wrecked car, with gasoline pouring everywhere. Other neighbors came out and stood at a distance wailing Muslim prayers. She shouted to them that it was not the Allah of Islam they should cry to, but Jesus. As they remained far away in fear of an explosion, she dragged the four bodies from the vehicle to a safe location. Although she and the crowd believed all four were dead, she prayed over them in Jesus' name. As she did so, all four suddenly stood to their feet while the crowd looked on in amazement! Before this, neighbors had always avoided the woman because of her Christian faith. Now she has a steady stream of visitors with lots of questions about Jesus. Pray that many of them will choose to become His followers.

Evolution is Stopped Cold by the Side Effects of Mutations!

Evolution needs mutations working together for one species to result in the next "just-so" species on the fantastic tree of life. But Pleiotropy bars the way!

Article Review: "The Pleiotropy Problem for Evolution", by Jerry Bergman

Marko's Executive Summary:

"Pleiotropy" is an awful sounding word. But the most awful thing about Pleiotropy is that it stops Evolution cold. If a mutation results in the loss or change in just one function of a living creature, it will probably also result in the loss of many other functions, too. And this will certainly disrupt all those mutations working together to produce a more advanced species.

This is why I'm calling this post "Evolution is Stopped Cold by the Side Effects of Accumulated Mutations!". That's the first item.

A second item is that Pleiotropy makes it extremely difficult for Evolution to explain how creatures like dogs and their wolf cousins supposedly mutated from their pre-wolf forebears. You see, dogs and wolves are a "high plasticity" life-form, as we all know from all the different breeds of dogs. Plastic species have a greater proportion of their traits coded by a single gene. So, how could all those very important single genes evolve perfectly from their ancestors, given the pitfalls of multiple side affects which would certainly bring the entire dog line down to its knees?

Pleiotropy runs counter to Evolution. As Jerry Bergman tells us in his paper titled "The Pleiotropy Problem for Evolution", not only does Pleiotropy "create a major genetic barrier to both micro- and macroevolution, but it also even sets limits on animal and plant breeding because of the biochemical interconnectivity existing in cells, tissues, organs, and organ systems." Evolution requires easy access to mutational avenues, but Pleiotropy is a great barrier.

In case you're asking the question "Where did dogs and wolves come from?", Bergman's answer is: "The evidence of pleiotropy favors special creation." What he means by "special" is that there was an intelligent designer at work to create dogs and wolves, not to mention all the other creatures as well.  Here is yet another place where the Creator God shows up in Science!

Abstract

Pleiotropy is the effect resulting from an interconnected genetic system in which a single gene influences many different biological systems in positive or negative ways.... Pleiotropy creates a major problem for evolutionary theory because the accumulation of mutations, even beneficial mutations, often has unintended negative effects.

Introduction

Pleiotropy - from pleio, meaning "many", and tropo, meaning "changes" - is defined as the situation in which a single genetic variant is responsible for a number of distinct and often unrelated phenotypic effects (King and Stansfield, 1997, p. 264). Genes never operate alone.... Even if a mutation is positive for one trait, negative effects frequently result as well, creating what is termed a "fitness cost". In humans the result is obvious when a single mutation causes a disease that produces many unrelated symptoms (Dudley et al., 2005).

The best-known example is ... sickle-cell anemia, a disease that results from a single mutation in the hemoglobin gene. Beside anemia, other physical complications include leg ulcers, bone problems, blood clots, anoxia caused by the abnormal blood cells that lack the ability to flow properly, spleen damage, strokes, and hemolysis.

Pleiotropy, Mutations, and Evolution


The disadvantage for evolution by mutations is: If a particular phenotype is the result of a mutation that produces the loss or alteration of a single function, it may also cause the loss of other functions that are required by disrupting part of a branching pathway.

This impediment to evolutionary progress is called "the cost of complexity" (Orr, 2000, p. 13).

How Common is Pleiotropy?

Much research indicates that most, and possibly all, genes have a pleiotropic effect.

Hodgkin (1998, p. 501) argued that pleiotropy "may well be the rule rather that the exception in higher organisms".... Jaroslav Flegr has proposed that pleiotropy limits the plasticity of a species (Hall, 2009). High plasticity life-forms, such as dogs, are able to produce many morphological variations, and plastic species have a greater proportion of their traits coded by a single gene.

Summary

Pleiotropy not only creates a major genetic barrier to both micro- and macroevolution, but it also even sets limits on animal and plant breeding because of the biochemical interconnectivity existing in cells, tissues, organs, and organ systems.... As Hodgkin (1998, p. 501) admitted, "In complex eukaryotes, pleiotropy may lead to major constraints on possible mutational avenues" that might allow evolution to occur.

Superhighway To Hell, by Stephen Saunders

Warning to the wise - this is where the present world of consumerism is headed!

"A phenomenon called "search inversion".... Today's Internet search function morphs from being a useful tool for users to search for products to an essential tool for companies to search for customers.

"User profiles become assets owned by the companies that developed them or, eventually, commodities to be bought and sold on "profile markets" or "identity exchanges"--the digital DNA equivalents of the financial and commodities exchanges on which stocks, oil, and gold are traded.

"Companies like Google and Facebook are pioneers in the areas of profiling and search inversion, but the Internet's nature (distributed, standards-based, open to all) makes it easy for others to follow their lead. Any Web company that owns servers storing user information can participate in profiling, as can any network service provider providing the pipes....

"By the middle of this decade, profiling will be commonplace. By the end of 2020 it will be the basis of a new industry, the Outernet, which in economic terms will have outgrown the commercial value of the Internet itself.

"The most immediate casualty of profiling is the hallmark of the 20th century Internet: anonymity (aka user privacy). The Internet of this century will be defined by identity....

"This is just the beginning. Let us sally forth, my friends, in our Chinese-made publishing time machine, to the year 2029. It is now exactly 40 years after the invention of the World Wide Web. The Internet has completed its metamorphosis to Outernet, a transformation marked by two tipping points that occur within a few years of each other:

"First, the Internet's primary role changes to that of surveillance network. The devices connected to the Internet whose function is to observe users via sensors, probes, spyware, and cameras now outnumber the devices that users employ to look at Internet content. The Internet is watching you.

"Second, the Internet profiling industry has matured. For the first time, the monetary value of the profiles about users exceeds the value of the digital information (music, television, gaming, business data) stored on the Internet itself.

"At this point, the Internet has become a sophisticated targeting system for companies to sell "stuff" to consumers, for governments to keep track of citizens, and for law enforcement to track illicit activity. In commercial terms, it will be an Internet where the user becomes the used."
