Only A Theory

Only A Theory is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Only A Theory rather than just read about it. In short: Only A Theory: Evolution and the Battle for America's Soul is a 2008 book by the American cell biologist and Roman Catholic Kenneth R. Miller.

Key takeaways

Only A Theory belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Only A Theory to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Only A Theory from memory before moving on to harder problems.

Reference excerpt

Only A Theory: Evolution and the Battle for America's Soul is a 2008 book by the American cell biologist and Roman Catholic Kenneth R. Miller. In the book, Miller examines the battle between evolution and intelligent design (ID), and explores the implications of the battle for science in America. The title of the book references the common misconception of what "theory" means in the context of science and evolution.

Reception Glenn C. Altschuler reviewed the book saying "Though I.D. trumpets its connections to information theory, biochemistry and molecular biology, Miller concludes, as did Judge John Jones in Kitzmiller v. Dover, it rests, ultimately, on ignorance. Extending an olive branch to religious Americans, Miller suggests that evolution and faith aren't really in conflict because all of nature is part of God's providential plan." Biologist PZ Myers wrote "Miller is a fine writer who sharply addresses the details of the arguments about intelligent design creationism. When tackling old chestnuts such as the 'only a theory' complaint, or Michael Behe's argument for a maximum limit for the number of genetic mutations, or William Dembski's rehash of William Paley's watchmaker argument for complexity, Miller discusses the contemporary biological explanations while refuting the errors." A number of reviewers had pointed out a factual inaccuracy in the book: on page 149, Miller referred to the Dingo as a marsupial, when in fact Dingos are feral dogs. In his list of errata, published online, Miller gave a correct reading of the passage: "It produced hunter-predator marsupials like the dingo and the Tasmanian tiger," should read "It produced hunter-predator marsupials like the tiger quoll and the Tasmanian wolf." On June 16, 2008, Miller was interviewed on The Colbert Report discussing the book.

Worked examples

Example 1 — a first encounter with Only A Theory

Start with the simplest possible case. Write down what Only A Theory claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Only A Theory before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Only A Theory ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Only A Theory

In research: Only A Theory appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Only A Theory in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Only A Theory is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2008 non-fiction books, Books about creationism, Books about evolution, so understanding it makes those chapters shorter.
In everyday life: Look for Only A Theory outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
