Epigenetics guides Laughter not Darwin


Laughter is an epigenetic phenomena. This means that it can cause changes in gene expression without altering the DNA sequence itself as with neo darwinism. These changes can be passed down from one generation to the next, and they can have a significant impact on a person's health and well-being.

There are a number of ways in which laughter can cause epigenetic changes. One way is through the release of hormones, such as endorphins and oxytocin. These hormones have been shown to have positive effects on gene expression. For example, endorphins have been shown to increase the expression of genes that are involved in stress reduction and pain relief. Oxytocin has been shown to increase the expression of genes that are involved in social bonding and attachment.

Another way in which laughter can cause epigenetic changes is through the activation of the parasympathetic nervous system. The parasympathetic nervous system is responsible for relaxation and rest. When laughter is activated, it can help to reduce the activity of the sympathetic nervous system, which is responsible for stress and anxiety. This can have a positive effect on gene expression, as it can help to reduce the expression of genes that are involved in inflammation and disease.

There is a growing body of evidence that suggests that laughter can have a number of positive health benefits. For example, laughter has been shown to:

  • Reduce stress

  • Boost the immune system

  • Improve cardiovascular health

  • Reduce pain

  • Increase lifespan

Epigenetics is a relatively new field of study, and there is still much that we don't know about how laughter affects gene expression. However, the research that has been conducted so far suggests that laughter is a powerful tool that can be used to improve our health and well-being.

The article: “Epigenetic dynamics in infancy and the impact of maternal engagement,” Science (10/19) by Krol et al. discusses this.

Introduction

Epigenetics is the study of changes in gene expression that do not alter the DNA sequence itself as with neo darwinism. These changes can be caused by a variety of factors, including environmental factors, lifestyle choices, and parenting practices. Epigenetic changes can have a profound impact on an individual's health and development, and they can even be passed down from one generation to the next.

One of the most important periods of epigenetic development is infancy. During this time, the brain is undergoing rapid development and is highly sensitive to environmental influences. Maternal engagement, which is the act of providing emotional support, nurturing, and stimulation to an infant, has a significant impact on epigenetic dynamics. Positive maternal engagement can promote healthy epigenetic changes, while negative maternal engagement can lead to adverse epigenetic changes.

Laughter and epigenetic dynamics

Laughter is a complex social behavior that is unique to humans. It is thought to be a form of emotional expression, and it has been associated with a number of positive psychological and physiological effects. Recent research has also shown that laughter can have a positive impact on epigenetic dynamics.

One study found that laughter can increase levels of oxytocin, a hormone that is known to have a number of positive effects on the brain and body. Oxytocin has been shown to promote bonding, trust, and relaxation. It has also been shown to protect against stress and anxiety. Epigenetics can turn genes on and off without random mutations.

Another study found that laughter can increase levels of brain-derived neurotrophic factor (BDNF), a protein that is important for brain cell growth and survival. BDNF has been shown to improve memory and learning, and it has also been shown to protect against depression and anxiety.

These studies suggest that laughter may have a positive impact on epigenetic dynamics by increasing levels of oxytocin and BDNF. These hormones can promote healthy epigenetic changes and protect against adverse epigenetic changes.

Maternal engagement and laughter

Maternal engagement is one of the most important factors that influences an infant's laughter. When mothers engage with their infants in a positive and playful way, they are more likely to elicit laughter. This laughter can have a number of benefits for the infant, including:

  • Promoting healthy epigenetic development

  • Reducing stress and anxiety

  • Improving memory and learning

  • Strengthening the bond between mother and infant

Maternal engagement can also help to protect infants from the negative effects of stress. When mothers are responsive to their infants' needs, they help to regulate their infants' stress hormones. This can help to prevent infants from developing long-term health problems, such as heart disease and diabetes.

Conclusion

Laughter is a powerful tool that can be used to promote healthy epigenetic development and protect infants from the negative effects of stress. Maternal engagement is one of the most important factors that influences an infant's laughter. When mothers engage with their infants in a positive and playful way, they are more likely to elicit laughter, which can have a number of benefits for the infant.

The concepts in this study challenges neo-Darwinism in several ways.

1. It highlights the role of non-genetic factors in development. Neo-Darwinism is a theory of evolution that emphasizes the role of natural selection acting on genetic variation. However, the study by Krol et al. shows that epigenetic changes, which are changes in gene expression that do not change the underlying DNA sequence, can also play a significant role in development. This suggests that non-genetic factors, such as maternal engagement, can have a profound impact on an individual's development.

2. It suggests that early experiences can have a lasting impact on gene expression. The study by Krol et al. found that maternal engagement during infancy was associated with changes in the methylation of the oxytocin receptor gene (OXTR) in infants. OXTR is a gene that is involved in social behavior, and the study suggests that early experiences can have a lasting impact on an individual's ability to form social bonds.

3. It challenges the idea that development is a linear process. Neo-Darwinism views development as a linear process, with each step leading to the next. However, the study by Krol et al. suggests that development is a more dynamic process, with epigenetic changes occurring throughout life. This suggests that an individual's environment can continue to influence their development even after they reach adulthood.

Overall, the study by Krol et al. provides a valuable contribution to our understanding of how development occurs. It challenges some of the core tenets of neo-Darwinism and suggests that non-genetic factors play a more important role in development than previously thought.

Beyond the Sequence: The Epigenetic "Fingers" That Play the DNA Keyboard

Image
Imagine the keyboard itself is not a standard piano keyboard, but a modular synthesizer, capable of producing an almost infinite array of sounds. The DNA sequence, then, represents the fundamental building blocks of this synthesizer, the raw materials from which all sounds are generated. Epigenetics, our "fingers," manipulates these building blocks, adjusting parameters like volume, timbre, and rhythm, transforming the raw potential of the DNA sequence into a symphony of cellular functions. We can further refine the "fingers" analogy. Consider that each finger represents a distinct epigenetic mechanism: DNA methylation, histone modifications, and non-coding RNA.  DNA methylation, for instance, might be the "index finger," capable of precisely silencing specific genes, like muting individual keys on the synthesizer. Histone modifications, the "middle finger," could represent the ability to adjust the accessibility of the DN...

Why are Christian philosophers running towards Darwin while biologists are "running" away?

Image
As nature reveals the strength of epigenetics and the weakness of Neo-Darwinism, biologists are “running” away from the long-standing accepted theory. In The Federalist , April 2019, Benjamin Dierker reviews “Why one-third of biologists now question Darwinism”: "Current estimates are that approximately one-third of professional academic biologists who do not believe in intelligent design find Darwin’s Theory inadequate to describe all of the complexity in biology.” Dierker continues, “The important note is that these are not ideologues or religious zealots, nor do they propose a god or biblical solution.  Rather, they find problems in the lack of explanatory power of Darwin’s theory in light of modern understanding of mutation, variation, DNA sequencing and more. These expressions of doubt do not reject naturalism or evolution per se, but the rigor of the Neo-Darwinian model for explaining the development of life.” For 40 years, scientists calculated natural se...

Rewriting the Rules: Epigenomic Mutation Bias Challenges Randomness in Evolution

Image
This research challenges the long-held dogma that mutations occur randomly, irrespective of their consequences, by demonstrating a clear, epigenome-mediated mutation bias in Arabidopsis thaliana . The study meticulously unveils how mutation rates are not uniform across the genome but are significantly reduced in functionally constrained regions, particularly within gene bodies and essential genes. This discovery fundamentally alters our understanding of evolutionary processes, suggesting that mutation is not a purely directionless force. "Mutation bias reflects natural selection in Arabidopsis thaliana" This opening statement encapsulates the core finding: mutation rates are not random but reflect epigenetic pressures. The authors demonstrate that mutations are less frequent in crucial genomic regions, directly contradicting the prevailing theory of random mutation. This observation suggests an active mechanism that minimizes deleterious mutations in essentia...
