Epigenetic Inheritance

Here’s an evolutionary article from phys.org seeking to provide hope for those who believe in both evolution and the dangers of climate change. But I don’t think it succeeds in either.

First, it sounds the alarm, claiming that climate change is happening so fast that it will be “hard for organisms and ecosystems to adapt.” But this isn’t anything new. Many animal species have gone extinct due to environmental factors, long before the Industrial Revolution. It may be sad, but if organisms can’t adapt to a changing environment, then they go extinct, while those that do adapt, survive. Survival of the fittest has been the name of the game from the beginning, according to evolutionists. But climate alarmists want us to believe it’s far worse now than ever before.

The article goes on to offer hope based on adaptation- specifically, epigenetics. Genetics involves changes in the DNA sequence, but epigenetics is concerned with traits not caused by changes in DNA, such as the expression of genes and how they’re transcribed.

To investigate the relationship between climate change and adaptation, an international team of scientists researched a species of fish- sticklebacks- and they’ve found that epigenetic changes do indeed affect adaptation. Nothing surprising there.

Stickleback fish have become popular in evolutionary circles because they’ve adapted to both saltwater and freshwater in a short period of time. In this experiment, investigators identified a chemical process whereby certain inducible markers, which can change over the course of an organism’s life, provide advantages to help the next generation cope with environmental changes.

This all sounds good. But then comes the bad news. According to Dr. Melanie Heckwolf, “the changes from one generation to the next are smaller than previously assumed.” This means that organisms aren’t safe from climate change. But we already knew that, right? That nasty ‘Survival of the fittest’ thing has caused many an organism to go extinct.

Dr. Heckwolf laments, “We have to be careful not to overinterpret this exciting but poorly understood field of research in epigenetics as a silver bullet against climate change for all species.” Of course not. I don’t know why anyone would have thought epigenetics could be a ‘silver bullet’. Based on past extinctions, we already knew it wasn’t. “Climate change is one of the greatest challenges for species and ecosystems,” she continues, “and the natural mechanisms available to species to respond may not be sufficient if climate change remains so strong and rapid.”

While I agree that a rapidly changing environment would inevitably cause some species to go extinct, I don’t believe the climate is changing as rapidly as some claim, and, therefore, there’s no reason to panic. We had 18 years without any significant increase in global temperatures, and some scientists are predicting another ice age right around the corner. Whether the climate is warming or chilling, it isn’t as dramatic as some would have us believe. The truth is, the climate has been changing since the beginning of time, and the organisms alive today found a way to survive, and the ones alive tomorrow will have found a way. This is a natural process that should be studied, not feared.

Human beings are remarkably resilient and adaptable; any time the climate has changed, we’ve dealt with it. And other organisms will join us. As I’m writing this, the Corona Virus (Covid-19) is the big pandemic many are worried about right now. But we humans will overcome this crisis like we have others in the past. Climate change pales in comparison.

Lastly, the writer mentions something startling: “Overall, the study shows that organisms will eventually reach their limits to respond to climate change, even with epigenetic modes of adaptation.”

Very true. And that’s just one good reason not to believe in Darwinian evolution. Climate change or not, organisms will reach a limit, and when they do, they can change no more. I’m sure evolutionists would like us to believe, in the past, climate change happened so slowly that organisms had time to evolve into different kinds of organisms. But, from what we’ve learned throughout recorded human history, and from what we’ve observed over the course of our lifetime, one kind of organism never evolves into another, and we never observe novel body forms or types. We’ve been around long enough that we should be able to point to such changes if evolution were true. But we don’t. Instead, as this article details, change has its limit.

A better explanation is special creation, whereby God created animals to reproduce after their kind. This is exactly what we observe, and what is supported by the scientific method as described in this article.
