A research article claimed that the facial muscle in dogs that leads to an expression similar to one that humans produce when sad “has evolved to appeal to humans.” This is a self-refuting evolutionist fairy tale that has no scientific ground and is completely against current findings.
The claim that a muscle develops from nothing is incompatible with the science of genetics and is against the anatomical findings. Both wolves and dogs have this muscle responsible for raising the inner eyebrow, but they are of different sizes. How these muscles act in a coordinated manner and express emotions is another great wonder entirely.
Gray wolves and domesticated dogs are genetically identical and their DNA encodes the same information regarding muscles.
Eyebrow muscle (levator anguli oculi medialis), which leads to the facial expression eliciting a caregiving, compassionate response, is present both in wolves and dogs. However, it is small in wild wolves because it is used less, and larger, and therefore easily detectable anatomically, in dogs because it is used frequently.
Data Conflicting with Evolutionary Interpretation
Although it is interpreted in the research article that the muscle that raises the eyebrow “has never been present” in wild wolves, it is accepted in the data section of the same article that a tendon blended with the fibers of this muscle are present there. This fact is a striking contradiction that overrides biased evolutionist interpretations. Obviously, the muscle, with its tendon and fibers, is present in wild wolves, but has remained smaller because it is only used less.
Besides, this muscle is not unique to domesticated dogs. Tigers (Panthera tigris) and servals (Leptailurus serval), which clearly do not need human nurturing in the wild, also have the same muscle.
Muscles Grow Larger When Exercised
A muscle that does not have any corresponding genes in the DNA does not come to exist on its own; likewise, it does not disappear on its own if there are genes for it. However, an unused muscle does shrink. Domesticated dogs, of course, keep doing this behavior, which was responded quite positively when they were puppies, as a conditioned behavior. Thus, the muscles that raise the eyebrows become more noticeable. A gray wolf, on the other hand, has no owner or caregiver to expect compassion from. In this case, it is an expected result that the unused eyebrow muscle becomes smaller.
The Miracle of Compassion in Living Things
It is incompatible with the facts to argue that an infant’s facial expression has arisen due to the need. Whether it is the wildest predator, it is thanks to a hormonal impulse bestowed by God that the mother takes care of her offspring, and this impulse has existed from the very beginning. Due to the oxytocin hormone secreted, the parent has a very strong sense of affection and protectiveness for the infant. It could never be claimed that oxytocin and the receptors in the target tissues have developed on their own over millions of years. The feeling of compassion is created by God, for which He created the oxytocin hormone. Feelings and behaviors in living things based on biochemical causes prove the existence of Almighty God.
