» Ageing Shouldn’t Exist in an Evolutionary World

Natural selection, as understood by evolutionists, should weed out factors that lead to ageing and death. 

Secular scientists are trying to solve an evolutionary puzzle. If natural selection tends to choose for genes which make individuals better at successfully reproducing and passing on their genes to the next generation, why is it that species don’t evolve to become eternal, thereby allowing them to pass on their genes forever?  We know that is not happening; members of all species eventually die.

According to recent research, it appears that a mechanism called autophagy is involved. Autophagy apparently not only helps promote health and fitness in young living organisms, but it also is responsible for ageing.

A theory by George C. William in 1953 attempted to solve this riddle. He said that natural selection is concerned only with caring for genes which improve reproductive success while paying no attention to what might be happening to the longevity of individuals. So, a large number of an individual’s descendents might help carry on its genes even if the organism must suffer a shorter lifespan. This idea is known as the hypothesis of antagonistic pleiotropy or AP. 

“Evolution becomes blind to the effects of mutations that promote ageing as long as those effects only kick in after reproduction has started. Really, ageing is an evolutionary oversight. … These AP genes haven't been found before because it's incredibly difficult to work with already old animals. We were the first to figure out how to do this on a large scale,” Jonathan Byrne, a researcher from Germany who co-authored a paper on the subject, said.

Byrne and his colleagues looked at genes in some old worms. They say they found the genes which are responsible for autophagy and promote ageing. When they shut down these genes, the worms lived longer lives but were crippled. Richard Richly, another researcher, suggested it might be better, if it were possible, to bypass autophagy altogether because of its negative consequences.

Comment: Readers can decide for themselves whether the scientists have provided an adequate answer to the question of why death exists in an evolutionary world. To me, their answer is not adequate; it sounds contrived.

Evolutionists have given natural selection incredible powers in that it is being credited with the ability to turn single-celled organisms into humans over eons of time. Natural selection is said to make wise choices, decisions which allow a species to always improve its chances of survival. So why hasn’t evolution gotten rid of autophagy it if that will eliminate ageing? Mr. Richly seems to think this would be a good idea.

Christians have the only reasonable answer as to why ageing and death exist in the world, and that answer is sin. “Therefore, just as sin entered the world through one man [Adam], and death through sin, and in this way death came to all people, because all sinned” (Romans 5:12). Attempts by humans today to eliminate ageing and death will never succeed.

But God has made it possible to eliminate ageing and death in a future world where sin has been eliminated, and that plan involves Jesus. “For if, by the trespass of the one man, death reigned through that one man, how much more will those who receive God’s abundant provision of grace and of the gift of righteousness reign in life through the one man, Jesus Christ!” (Romans 5:17).

All believers in Jesus Christ as their Savior will in heaven be forever ageless.

QUESTION OF THE DAY

Is having a dry mouth a result of getting older?

Having a dry mouth is not a direct result of ageing, but it can be a symptom of some age-related conditions. More than 400 medications can cause dry mouth including blood pressure drugs and anti-depressants. People with obstructive sleep apnea often wake up with a dry mouth.

About Me--Warren Krug The Editor
Decades ago I attended a so-called Lutheran university where I could have lost my faith. The science professors promoted the theory of evolution and made fun of anybody who believed in the account of creation as presented in the book of Genesis. Thanks be to God, some creationist literature and the Bible soon helped get me back on the right track. Ever since then I have taken an active interest in the creation/evolution controversy.
