The theory of evolution, while widely accepted in the scientific community, is not without flaws from a biblical perspective. Here are some potential issues that arise when examining evolution through the lens of Scripture:
Lack of Transitional Fossils
According to the theory of evolution, complex life forms gradually evolved from simpler ones over billions of years. However, the fossil record does not contain enough transitional fossils demonstrating this gradual change. There are some disputed examples, like Archaeopteryx which shows signs of being both a dinosaur and early bird. But overall, there are gaps in the fossil evidence showing clear evolutionary transitions (Genesis 1:20-25).
Irreducible Complexity
Many biological systems are irreducibly complex, meaning they require multiple interconnected parts to function properly. Remove one part, and the whole system fails. Examples include the human eye, the blood clotting cascade, and the bacterial flagellum. According to critics, these systems could not have evolved gradually because the incomplete versions would not work at all. Their coordinated complexity seems to indicate intentional design (Psalm 94:9).
Lack of Mechanism
While natural selection can explain how existing genetic variations are sorted, it does not provide a satisfying account of where those variations come from in the first place. Random genetic mutations are an insufficient mechanism, as even small changes tending to degrade functions rather than improve them. No known natural mechanism can generate the new genetic information required for increasing complexity (Genesis 1:11-12, 21).
Abrupt Appearance of Groups
The fossil record shows abrupt appearance of major animal body plans without transitional fossils linking them to common ancestors. In the Cambrian explosion, complex aquatic life suddenly emerges without clear evolutionary precursors. Darwin recognized this as a weakness, hoping future discoveries would fill in the gaps. But abrupt appearance persists today despite extensive fossil-hunting (Genesis 1:20-23).
Limits of Species Change
While selective breeding and microevolution within species are well-established, there are limits to change. Attempts to blend species through hybridization does not lead to new stable species. The inherent variability within organisms appears bounded, preventing large-scale transformation from one kind of plant or animal into a fundamentally different one (Genesis 1:11-12, 21, 24-25).
Irreconcilable Timescales
According to evolutionary theory, life originated 3.5 billion years ago. But scientifically determined ages of rocks, stars, and other natural clocks indicate the universe itself is only billions of years old—a major problem for the time required by evolution (Exodus 20:11). Discordant radioisotope dating methods and changing decay rates assumptions undermine confidence in deep time.
Lack of Supporting Evidence
Science is based on observation and repeatability. But no one has directly observed one species evolving into a totally different kind of plant or animal. The fossils and other indirect evidence are circumstantial and open to interpretation. Meanwhile, controlled lab experiments intended to simulate evolutionary processes expose their limits (Job 10:8-12).
Nonviability of Intermediates
The improbability of complex new features arising from random mutation is compounded when intermediate transitional forms would not confer any survival advantage. What use would partially formed wings or partially connected bones be? Partial stages toward entirely different bodily systems would not offer any improvement that natural selection could favor (Psalm 139:14).
Cambrian Predation
The Cambrian explosion contains the first appearance of predators like Anomalocaris. According to critics, their unique structures and behaviors could not have developed through co-evolution, as their prey did not yet exist. Top-down pressure from predators is argued as necessary for many defense/offense systems hypothesized under evolution (Genesis 1:30).
Lack of Selective Pressures
Changes in diet, climate, competition, and other selective pressures are hypothesized as drivers of evolutionary change. But for much of the fossil record, those pressures are not documented. For example, the environmental conditions present during key transitions like fish to amphibians are still unknown and thus cannot be shown as selective forces (Genesis 1:29-30).
Assumptions About Early Atmosphere
Chemical evolutionary models depend heavily on assumptions of early atmospheric conditions. But evidence indicates the primitive atmosphere was likely not reducing as hypothesized. Additionally, localized environments of concentrated chemicals from atmospheric reactions are needed, but speculations about geological phenomena producing them remain unverified (Genesis 1:6-8).
Unrealistic Timescales
Lab simulations of chemical evolution of life depend on prolonged exposure to selective agents like UV, concentrated chemicals, temperature gradients, etc. But experts acknowledge those conditions likely did not persist for long enough in any natural setting to produce life, raising doubts about the plausibility (Exodus 20:11).
Missing Transitions Between Kingdoms
Evolution from inorganic chemicals to the first cell remains entirely speculative, with vast gaps between self-replicating molecules and fully functioning cells with information storage, metabolic systems, membranes, etc. The transitions between animal, plant, fungi, and other kingdoms are also missing. Each has unique complex properties appearing abruptly in the record (Genesis 1:11-12, 20-25).
Lack of Known Mechanism
There is no known naturalistic explanation for the origin of genetic information and the coding, decoding, and translation systems in even the most primitive cells. Attempts to simulate conditions that produce building blocks like amino acids shed no light on the mystery of how life could have assembled itself spontaneously (Acts 17:24-26).
Biological Similarities
Evolution predicts a branching tree pattern in similarities as organisms gradually diverge over time. But statistically analyzing biological data reveals networks and clusters more akin to designed re-use of common modules like a programmer employing reusable code or an engineer reusing parts. This suggests common design rather than solely common descent (Romans 1:20).
Falsification of Nested Hierarchy
Evolution predicts that organisms are related in a neat nested hierarchy from older common ancestors. But discordant gene trees, lateral gene transfers, and convergent evolution repeatedly falsify this tight top-down pattern. The messy bush-like pattern of connections imperfectly fits evolutionary expectations (1 Corinthians 15:39).
Non-optimal “Jury-rigged” Designs
Suboptimal compromises in nature are cited as evidence of evolution’s blind tinkering rather than intentional design. But optimality depends on engineering purpose and tradeoffs. Critics argue perceived imperfections are actually elegant, efficient designs within space, material, and functional constraints (Proverbs 20:12).
Usefulness of Imperfect Structures
Vestigial organs and redundant pseudogenes are claimed as relics of evolution’s stages. But functions continue to be discovered for these puzzling parts. Though distorted by the Fall, critics argue God’s original designs retain purpose even where human understanding remains limited (Romans 1:20).
Inverted Retinal Wiring
The “backward” wiring of the vertebrate retina with blood vessels in front of photoreceptors is often called poor design. But optics experts note multiple benefits of this layout, suggesting reasons why re-engineering the retina would make vision worse. Its physiological constraints point to an ordered universe rather than random tinkering (Proverbs 3:19-20).
Overly Complex Outcomes
The indirect blind watchmaker mechanism of natural selection seems incapable of generating many remarkably complex integrated systems vital to life. Critics argue their coordinated, information-based, multi-part functionality bears the unmistakable marks of intentional creative design, not undirected processes (Romans 1:19-20).
Denial of Purpose
Evolution purports to explain all living things through impersonal natural laws and chance. But this effectively denies obvious elements of purposeful complex design and meaning infused throughout nature by its Author. Critics argue we should expect to see forethought, intent, and rationality if our minds come from the Mind behind the universe (Genesis 1:28).
Contradictory Order of Events
The order and timing of events in evolutionary history directly contradicts the biblical account of creation. Examples include birds before land animals, sun before plants, marine animals before land, extinction events before man’s sin, death before the Fall, man long after beginnings, and many others (Genesis 1).
Reliance on Speculative Scenarios
Attempts to account for the origin of species or complex biological features involve speculative just-so stories rather than demonstration. These imaginative scenarios rely heavily on the assumption of evolution rather than observation. Their conjectural nature makes them unverifiable and unfalsifiable (2 Peter 1:16).
Expressions of Faith
Leading evolutionists routinely express faith-based statements about evolution’s unobservable past and their belief that wide gaps in understanding will someday be filled in. Critics argue this exposes evolution’s religiously held status as a philosophical worldview, rather than purely scientific and evidence-based (Hebrews 11:1).
Methodological Naturalism
Evolution is based on the assumption of naturalism—only material natural causes can be considered in science. This excludes intelligent causation and design by default. Critics argue this biased approach predetermines outcomes rather than following evidence wherever it leads, preventing fair consideration of alternative possibilities (Acts 17:24-28).
Lack of Falsification Criteria
To qualify as a scientific theory, critics argue evolution must make testable predictions that offer the possibility it could be falsified. They argue no amount of contradictory evidence seems sufficient to overturn evolution’s foundational assumptions due to an overriding commitment to philosophical naturalism (1 Thessalonians 5:21).
Data Interpretation Disputes
Debates over evolution often center on how data and facts should be interpreted. Both critics and supporters select evidence that fits their existing perspective. This reveals the role of starting assumptions which mold conclusions, showing evolution’s status as an inferred historical narrative imposed on data (Proverbs 18:17).
Unresolved Weaknesses
Mainstream evolution literature acknowledges many ongoing unresolved weaknesses in the theory. Some have persisted for decades with no satisfying solutions in sight. Critics argue new discoveries continually uncover additional problems rather than shoring up the theory and confirming predictions (1 Timothy 6:20-21).
Revolutions in Understanding
Scientific revolutions often dramatically change theories when new discoveries overturn entrenched ideas. Given its ongoing major difficulties and reliance on 19th century evidence, critics argue evolution is ripe for revolution. Some expect breakthroughs that entirely topple current naturalistic beliefs (1 Corinthians 3:19).
Presumption of Naturalism
Evolutionists generally begin inquiry with the philosophy that science must explain everything in nature through purely material causes and without reference to design or purpose. Critics argue this stacks the deck in favor of evolution through nationalistic presuppositions rather than allowing the evidence to lead the conclusion (Colossians 2:8).
Circular Reasoning
Key evidence cited for evolution depends on the assumption that evolution is true. Clear examples of this circularity include radiometric dating methods calibrated against fossils presumed to be ages already settled, or phylogenetic trees assuming common descent (Hebrews 11:3).
Unwarranted Extrapolations
Microevolutionary changes within existing biological parameters are extrapolated without justification across profound gaps to encompass grand macroevolutionary transitions. Critics argue limited variation does not imply ability to transform fundamental body plans and generate new complex biological information (Romans 1:20-23).
Reliance on Theoretical Simulations
Attempts to demonstrate evolutionary feasibility often rely on artificial computer programs designed with built-in evolutionary assumptions. Their ability to generate outcomes through computational iterations sheds no light on whether undirected material processes could realistically accomplish such creative innovation (Psalm 94:9-11).
Preexisting Intelligence
Evolutionary simulations rely on preexisting human intelligence and understanding to structure algorithms and provide meaningful target goals. Critics argue this demonstrates intelligent guidance is required to produce information, not simply chance and necessity (Proverbs 2:6).
Illegitimate Theological Claims
Evolution is routinely used to make claims beyond science about God, faith and theology. Critics argue many evolutionists illegitimately go beyond their expertise by promoting naturalistic philosophy in the name of science (Colossians 2:8).
Abandoning Causality
Some evolutionists propose abandoning the search for causality, claiming we must simply accept the brute fact that the universe exists. Critics argue this irrational position reveals the absurd logical implications of naturalism taken to its ultimate conclusion (Psalm 14:1, Romans 1:19-20).
Conflicts with Scripture
Scripture clearly teaches God specially created different kinds of organisms to reproduce after their kinds. Human death and suffering is attributed to human sin. But evolution’s conflicting order of events and mechanism deny the Genesis account of divine creative acts and the Fall. Critics argue Scripture has supremacy for Christians if conflicts arise (2 Timothy 3:16-17).
