Which of the following is NOT considered one of the evidences for bio-evolutionary theory?

The concept of irreducible complexity is often cited in arguments against evolutionary theory, rather than providing evidence for it. Irreducible complexity suggests that certain biological systems are too complex to have evolved from simpler, successive forms through natural processes. This idea is typically associated with arguments from proponents of intelligent design, who assert that some structures cannot possibly function if they were any simpler, indicating that they cannot have evolved incrementally.

In contrast, transitional fossils, genetic mutation, and natural selection are all well-established concepts that provide robust evidence supporting the theory of evolution. Transitional fossils serve as critical physical documentation of evolutionary change, showcasing intermediate forms between different species. Genetic mutations are the mutations that drive variations within a species, creating the necessary diversity for evolution to occur. Natural selection describes the process whereby organisms better adapted to their environment tend to survive and reproduce, passing on advantageous traits to future generations.

Therefore, irreducible complexity does not align with the evidences that support evolutionary biology, making it the correct answer in this context.
