The Theory of Evolution: How To Be An Atheist (Part 2) - Apologetics Series - Episode 3

Introduction

The host introduces the topic of the episode and the guest, Father Paul Robinson. They discuss how evolution is often used as an argument against God's existence.

Evolution and Atheism

Father Robinson discusses how atheists use Darwin's theory of evolution to argue that nature explains itself and there is no need for a Creator. He emphasizes that even if evolution explains the diversity of life on Earth, it does not negate the need for a first cause of existence.

Darwin's Theory of Evolution

• Darwin's theory seeks to explain all biological diversity through natural forces.

• Atheists often use this theory to support their belief that God is not necessary.

• The Catholic Church has never been opposed to material evolution as such.

Need for a First Cause

• Even if evolution explains all biological diversity, we still need a first cause of existence.

• The beings around us are contingent, so we would still need a first cause of their existence.

• Either way, God's glory is supported because he pre-loaded nature with the capacity to evolve in a certain direction.

Conclusion

Father Robinson concludes by emphasizing that Catholics can believe in both creation and evolution as long as they acknowledge God as the first cause. He also encourages listeners to support good Catholic content production through donations.

Can Nature Explain Itself?

In this section, the speaker introduces the topic of whether nature can explain itself and what an atheist would have to find in reality to make a compelling case for it.

Three Levels of Being

• There are three basic ontological levels of complexity of being: non-living, living but non-rational, and living and rational.

• The difference between animals and humans is that humans possess self-consciousness, the power to understand concepts and know themselves as separate entities from other things.

• If atheists want to claim that nature explains itself, they must prove that all three levels develop by natural law. This implies a certain order and intelligence embedded into nature.

Life vs Non-Life

• Abiogenesis is the idea that life can come from non-life through natural forces. However, there is a massive gap in complexity between even the least complex living things and the highest non-living things.

• According to scientist Michael Denton, there is a vast chasm in order and complexity between a living cell and the most highly ordered non-biological system such as a crystal or snowflake.

The Complexity of Life

In this section, the speaker discusses how complex life really is compared to what people used to believe.

Complexity of Living Things

• Living things are incredibly complex with intricate systems that work together seamlessly.

• Even single-celled organisms have complex structures like flagella that allow them to move around.

• DNA contains information for building proteins which are essential for life processes. The information contained in DNA is incredibly complex.

The Limits of Science

• Science can only explain the physical aspects of life, but it cannot explain the meaning or purpose behind it.

• The complexity of life points to a designer or creator rather than random chance.

The Fine-Tuning Argument

In this section, the speaker discusses the fine-tuning argument for the existence of God.

The Fine-Tuning Argument Explained

• The universe is finely tuned for life with many constants and parameters that must be just right in order for life to exist.

• This fine-tuning cannot be explained by chance or necessity alone.

• Therefore, there must be a designer or creator who intentionally set these parameters to allow for life.

Objections to the Fine-Tuning Argument

• Some objections to the fine-tuning argument include the multiverse theory and natural selection.

• However, these objections do not fully explain away the fine-tuning and still require some level of design or intentionality.

Darwin's Theory and the Gap Between Living and Non-Living Things

In this section, the speaker discusses Darwin's theory and its limitations in explaining the transition from non-living to living things. The speaker also talks about the theory of biogenesis and the idea of a primordial soup.

Darwin's Theory Only Covers Transition Between Simple and Complex Life Forms

• Darwin's theory only covers the transition from simpler living things to more complex ones.

• People have proposed theories like biogenesis to explain the gap between non-living and living things.

• The idea of a primordial soup suggests that life emerged from a sequence of chemical events in a swamp-like area struck by lightning.

Nature Cannot Produce Life From Non-Life

• Scientists have not been able to find any possible bridge between non-life and life.

• Even with advances in science, scientists cannot produce even basic building blocks of cells or proteins from non-living things.

• We need to understand why it is impossible for living things to come from non-living things by looking at the basic building blocks of all living things.

Cells are Complex Factories

• All living things work on cells, which are complex factories producing molecular machines that sustain life processes.

• Proteins are the main workers in cells, built from amino acids assembled into molecular machines called ribosomes.

• Proteins fold together chemically bonded amino acids to perform specific functions in cells.

Can Nature Form Proteins Other Than In Cells?

• Proteins are formed in cells using DNA as a database containing instructions on how to form them.

• A single protein may have 150 amino acids concatenated next to one another, making it difficult for nature to form them outside of cells.

The Probability of Protein Formation

In this section, the speaker discusses the probability of protein formation and how it is highly unlikely to occur through random events.

Combinatorial State of Amino Acids

• Researchers have looked at all possible combinations of amino acids to form proteins.

• Very few combinations actually form functional protein.

• The chances of getting any functional protein from a random series of events over time are one in 10 to the 164th power.

Raw Materials for Simplest Cell on Earth

• To get the raw materials for the simplest cell on Earth, we would have to hit that jackpot 482 times in short order.

• The chances of assembling raw materials and coordinating them with one another are pretty much zero.

Complexity of DNA

In this section, the speaker talks about DNA and its complexity.

Discovery of Genetic Code

• Francis Crick and James Watson discovered the structure of our genetic code in 1953.

• DNA contains all instructions necessary to make our body what it is.

Production Process for Proteins

• DNA contains the code necessary to instruct cells how to produce proteins necessary for sustaining life.

• RNA is produced from a strand of DNA that contains nucleotide bases.

The Complexity of Life

In this section, the speaker discusses the complexity of life and how it is not reasonable to think that life could come from non-life.

Life as a Computer Code

• Messenger RNA reads three nucleotide bases and summons a certain amino acid based on their sequence.

• A string of amino acids must fold into a certain shape to attach itself to certain areas in the cell.

• DNA contains the equivalent of a computer code that is interpreted by every single living thing on this planet.

• The only thing capable of producing computer code is an intelligent mind.

Mutual Dependency Between DNA and Protein

• Proteins build DNA, and DNA contains the code to produce proteins.

• To produce the first cell, you have to produce the thing that produces protein as well as proteins that produce DNA at the same time.

Evolutionary Theory

• Even if we give evolutionary theory the benefit of doubt, there's still only one in 40 quadrillion chance that everything happened over 25 billion years.

The Origin of Life

In this section, the speaker discusses the possibility that life on Earth was seeded by aliens through directed panspermia. He also introduces Darwin's theory of evolution and natural selection.

Directed Panspermia

• Life on Earth may have been seeded by aliens through directed panspermia.

• Directed panspermia is the idea that aliens came to Earth and seeded it with life.

• This theory raises questions about where the aliens came from and where their own life originated.

Darwin's Theory of Evolution

• Darwin proposed a way to explain the development of more complex life forms from less complex ones.

• Richard Dawkins believes that Darwin's theory provides a sufficient explanation for the diversity of life forms on Earth.

• Darwin's theory involves natural selection, which is a metaphorical process in which nature selects organisms with certain genetic characteristics that enable them to survive and reproduce.

Natural Selection

• Natural selection is based on survival of the fittest, meaning organisms with certain genetic characteristics are more likely to survive and reproduce.

• Nature does not actually select organisms; rather, those with advantageous traits are more likely to survive and pass on their genes.

• Malthusian theory inspired Darwin's idea of natural selection as he applied Malthus' ideas about competition for resources among humans to all living things.

Darwin's Theory of Evolution

This transcript discusses Charles Darwin's theory of evolution and the scientific information available during his time. It also explores the two aspects of his theory: common descent and random mutation in natural selection.

The Theory of Evolution

• Survivors are better and superior than those who died, which is why they survived.

• Darwin proposed a mechanism to explain the biological world through natural causes, but it had yet to be tested due to lack of scientific information at that time.

• Darwin's case was strong for some theories, including the descent of modern organisms from earlier ones, but weak for his proposed mechanism of evolution.

Common Descent

• Common descent proposes that all life forms ultimately derived from simpler life forms in the past through a long-term process of evolution.

• Morphology is one piece of evidence that points to some animals coming from other animals. Biologists classify animals based on similarities in body plans or phyla.

• The fossil record shows a progression from less complex to more complex animals as you go deeper into layers.

Random Mutation in Natural Selection

• The capacity for random mutation in natural selection is another aspect of Darwin's theory that needs to be examined.

• Observing changes capable of being produced in genetic code today can help determine if nature produces favorable changes over long periods of time.

Introduction to Evolution

In this section, the speaker introduces the concept of evolution and discusses three pieces of evidence that support it.

Evidence for Evolution

• The fossil record shows a progression from simpler to more complex organisms.

• DNA analysis reveals similarities between related species and differences between distantly related ones.

• Similarities in protein structure suggest common ancestry among different species.

Criticisms of Darwinian Evolution

In this section, the speaker discusses criticisms of Darwinian evolution and alternative explanations for the evidence presented earlier.

Intelligent Design

• Similarities among animals could be due to an intelligent designer creating variations on one theme.

• Variation is a common feature in technology and music, suggesting that intelligent minds like to create variations on existing themes.

Insufficiency of Evidence

• The evidence presented so far is not conclusive proof of Darwinian evolution.

Introduction to Darwin's Theory of Evolution

In this section, the speaker introduces Darwin's theory of evolution and discusses the evidence that supports it.

Darwin's Hypothesis

• The speaker discusses whether the similarity among animals is produced by random mutation and natural selection, which is the cause that Darwin proposes.

• The speaker talks about how Darwin observed different species of finches on the Galapagos Islands and how their beak size changed during a drought.

• The speaker explains how only finches with big beaks survived during a drought, leading to a diversification in biological form.

Predictions of Darwin's Theory

• The speaker explains that if Darwin's theory is true, it should predict certain things in nature.

• One prediction is that there should be great continuity between various life forms, from protozoa or bacterium to man.

• Another prediction is that it should be easy to change living things and introduce new functions through genetic modification.

Challenges to Darwin's Theory

In this section, the speaker discusses challenges to Darwin's theory of evolution.

Life Forms are Strictly Bounded

• The speaker explains that life forms are very set in what they are and do not allow themselves to be easily changed into other things.

• There are strict boundaries between different types of life forms with an immense gap that cannot be bridged by genetic modifications.

• When pushed, life forms either die or mutate into something bizarre and non-functional.

The Limits of Breeding and Saturation Mutagenesis

This section discusses the limits of breeding and saturation mutagenesis in genetic modification.

Breeding Limits

• Crossbreeding can increase sugar content, but there are limits to how much it can be increased.

• Luther Burbank recognized the constraints of breeding and stated that getting a plum larger than a grapefruit is impossible.

• There are upper limits in the DNA or code of living things that prevent them from changing into another species or kind.

Saturation Mutagenesis

• Scientists have experimented with saturation mutagenesis, which involves modifying genetics in all possible ways.

• Two German geneticists executed a saturation mutagenesis experiment on fruit flies starting in 1979.

• Most mutants perished as deformed larvae before achieving reproductive age, while others survived with major changes that were deleterious.

• None of the fruit flies turned into a new species with greater functionality.

Evolutionary Changes

• Large-scale macroevolution is impossible due to animals not tolerating mutations at the beginning of development, which is the only time they can be changed substantially.

• Animals do tolerate mutations after they have developed, but such mutations can only induce minor changes.

• Empirical evidence indicates that gradual changes cannot accompany corresponding changes at every stage for beneficial change.

The Continuum of Life

In this section, the speaker discusses the idea of a continuum in life and how it affects the diversification of species.

The Continuum and Natural Selection

• The Continuum is a concept where life forms gradually change over time.

• Gene mutations and defects usually mean that the animal dies or is wiped out by natural selection because it cannot eat or reproduce.

• This contradicts what we would expect from Darwin's theory, which predicts gradual diversification from the lowest taxonomical categories.

Explosions in Taxonomical Categories

• Instead of gradual branching out, there are explosions in taxonomical categories such as the Cambrian explosion.

• The Cambrian Period saw a sudden appearance of different animal phyla with different body plans.

• This contradicts Darwin's prediction of gradual diversification from one species to another.

Top Down Progression

• The fossil record shows top-down progression instead of bottom-up progression predicted by Darwin's theory.

• Great diversification happened first, followed by lower taxonomical categories developing within those differences.

• This contradicts Darwin's predictions and suggests some sort of intervention or creation.

Nature's Strategies to Prevent Competition

In this section, the speaker discusses how nature employs various strategies to prevent competition among different species.

Darwin's View of Nature

• Darwin saw nature as "red in tooth and claw," where animals compete for resources.

• Only some animals are able to get the resources, giving them a survival advantage and leading to their evolution.

Analyzing the State of Nature

• Ecologists have analyzed the state of nature and found that it is not always characterized by great competition.

• Different species occupy different ecological niches, preventing direct competition.

• Migration and sequential flowering are examples of strategies used by plants and animals to avoid competition.

Symbiotic Relationships

• Symbiotic relationships between different species help maintain harmony in nature.

• The whole plant kingdom produces oxygen needed by animals while the animal kingdom produces carbon dioxide needed by plants.

• Ecologists are concerned about endangered species because removing one piece from an ecosystem can disrupt its harmony.

Examples from Yellowstone Park

• The reintroduction of wolves into Yellowstone Park restored balance and harmony among different species.

• Wolves did not eliminate deer but made it possible for vegetation to flourish, benefiting both deer and other herbivores.

Conclusion: Importance of Maintaining Harmony in Nature

In this section, the speaker emphasizes the importance of maintaining harmony in nature through symbiotic relationships and avoiding disruption caused by invasive species or removal of key components from ecosystems.

Importance of Harmony in Nature

• Removing one component from an ecosystem can cause chaos and disrupt its harmony.

• Symbiotic relationships between different species help maintain balance in nature.

Disruption Caused by Invasive Species

• Invasive species like Asian carp can cause chaos and take over an ecosystem.

• Ecologists are concerned about the impact of invasive species on ecosystems.

Final Thoughts

• Nature is not always characterized by competition, and different strategies are used to prevent it.

• Maintaining harmony in nature is important for the survival of different species.

Assumptions of Evolution

In this section, the speaker discusses the last assumption of evolution which concerns mutations that take place in genetic code. The speaker explains how random mutations can create new functions and provide a survival advantage to animals.

Genetic Mutations

• Darwin did not understand genetic code, but later scientists modified his theory by specifying what random mutation meant.

• Random mutations occur when DNA is copied imperfectly during transcription, creating new functions over time.

• Scientists investigate cases where genetic code has been changed to see if it provides a survival advantage.

• Research shows that sometimes random mutations do create a survival advantage for animals.

Survival Advantage through Breaking of Genetic Code

• Animals that survive gain their survival advantage through breaking their genetic code, meaning they have less function than those who died.

• Positive selected mutations damage and organize organisms' genetic information either degrading or outright destroying functional coded elements.

• Examples of genes being broken in nature provide a survival advantage to animals, but natural selection cannot rebuild the function.

• If an animal's genetic code is perfect for its environment, there are no examples of brand new mutation building some sort of function in an animal.

Genetic Modification and Evolution

In this section, the speakers discuss genetic modification and its effects on dogs. They also talk about the evolution of polar bears and how it relates to Darwin's theory.

Genetic Modification of Dogs

• Modifying the genetic code of dogs can only make them worse than what they are made to be.

• Specific dog breeds have health problems due to their genetic modifications.

• Dachshunds are an example of a breed that is genetically modified to have a specific shape but cannot function well in the wild.

Evolution of Polar Bears

• Polar bears evolved from brown bears by breaking or blunting genes for regulating fat and metabolizing cholesterol.

• This had a side effect of changing their coat color while allowing them to survive on fatty diets in cold climates.

• New mutations are not capable of producing new functions but can break things, which sometimes provides survival advantages.

Limitations of Darwin's Theory

• Random mutation and natural selection cannot produce new functions as expected by Darwin's theory.

• Writing new code is necessary for introducing new functions, just like in computer programming.

• The transition period during genetic modification is broken, making it difficult for programs to run properly.

Edge of Evolution

• Michael Behe tries to find the edge of evolution and concludes that it can only produce maybe a new family at most.

• Evolution cannot go up to higher taxonomical categories beyond that point.

The Gap Between Material and Spiritual

In this section, the speaker discusses the gap between material and spiritual things. He uses the example of a movie where an ape develops intelligence after receiving chemicals to explain that intelligence is a spiritual faculty.

Evolution's Capabilities

• Darwinian evolution cannot produce a highly evolved ape or humanoid form.

• There is a genetic void between humans and apes that can only be bridged by reprogramming DNA with an intelligent mind.

• The gap between non-life and life, material and spiritual, can only be bridged by a purposeful intelligent mind.

Biological Diversity

• The great variety of biological diversity we see before us has only one adequate cause: someone who is really smart and really powerful.

Conclusion

In this section, the speakers conclude their discussion on traditional Catholicism. They encourage listeners to subscribe to their podcast and leave ratings or reviews to help others discover the beauty and truth of traditional Catholicism.

Final Thoughts

• Listeners are encouraged to subscribe to the podcast on various platforms.

• Leaving ratings or reviews will help more people discover traditional Catholicism.
