Irreducible complexity is at its core an argument against evolution.

This article covers irreducible complexity as used by those who argue for intelligent design.

In their theory, they describe how certain mutation and changes can cause apparent irreducible complexity.

His work has been discussed in arguments concerning intelligent design and "irreducible complexity."

There has also been a theory that challenges irreducible complexity called facilitated variation.

He argues that irreducible complexity in an object guarantees the presence of intelligent design.

Hermann Muller, in the early 20th century, discussed a concept similar to irreducible complexity.

The theory challenges Irreducible complexity by explaining how mutation can cause unusual changes within a species.

Other than briefly addressing issues of irreducible complexity, Expelled examines it as a political issue.

Summers apparently cannot abide this irreducible complexity of politics.

Such an argument bears similarities to irreducible complexity, a common argument against evolution.

In explicating his definition of "irreducible complexity" he notes that:

It is frequently cited by intelligent design and creationism advocates as an example of irreducible complexity.

Like intelligent design, the concept it seeks to support, irreducible complexity has failed to gain any notable acceptance within the scientific community.

If irreducible complexity is an insurmountable obstacle to evolution, it should not be possible to conceive of such pathways.

The core argument for intelligent design - the supposedly irreducible complexity of key biological systems - has clear theological overtones.

Specified complexity is one of the two main arguments used by intelligent design proponents, the other being irreducible complexity.

"Professor Behe's concept of irreducible complexity depends on ignoring ways in which evolution is known to occur.

Potential evolutionary pathways have been provided for all of the systems Behe used as examples of irreducible complexity.

Behe's argument of irreducible complexity puts forward negative arguments against evolution but does not make any positive scientific case for intelligent design.

Proponents say evidence exists in the forms of irreducible complexity and specified complexity that cannot be explained by natural processes.

The term "irreducible complexity" was coined by Behe, who defined it as applying to:

The argument from irreducible complexity attempts to demonstrate that certain biological features cannot be purely the product of Darwinian evolution.

Other critics take a different approach, pointing to experimental evidence that they believe falsifies the argument for Intelligent Design from irreducible complexity.

However, the paper does not mention intelligent design nor irreducible complexity, which were removed, according to Behe, at the behest of the reviewers.
