No Struggle for Existence, No Natural Selection

No Struggle for Existence, No Natural Selection 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 No Struggle for Existence, No Natural Selection rather than just read about it. In short: No Struggle for Existence, No Natural Selection: A Critical Examination of the Fundamental Principles of the Darwinian Theory is a 1908 book by George Paulin. Paulin argues in the book that there is no struggle for existence in nature and that all small individual variations are eventually eliminated by cross-breeding.

Key takeaways

No Struggle for Existence, No Natural Selection belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect No Struggle for Existence, No Natural Selection to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of No Struggle for Existence, No Natural Selection from memory before moving on to harder problems.

Reference excerpt

No Struggle for Existence, No Natural Selection: A Critical Examination of the Fundamental Principles of the Darwinian Theory is a 1908 book by George Paulin. Paulin argues in the book that there is no struggle for existence in nature and that all small individual variations are eventually eliminated by cross-breeding. The book heavily criticized Charles Darwin's writings on natural selection and also attempted to refute Malthusian theory. The book was negatively reviewed in the British Medical Journal claiming "we are not sufficiently impressed by [the] author's arguments". One of Paulin's main arguments was that carnivora rarely attack each other and the male in all species is found to kill the young at birth. Paulin stated that "Darwin's conception of the cruelty of nature to her sentient offspring is wholly mistaken." He argued that the struggle for existence emphasized by Darwin was immoral. This was disputed by a reviewer who wrote that Paulin's idea that there was no struggle for existence amongst animals, because of the destruction of young offspring by males is "more revolting than the most horrible struggle for existence suggested by Darwin and the attempt to fix a charge of immorality upon scientific theorems with which we do not agree is itself of doubtful morality." The philosopher Edmund Hollands also negatively reviewed the book pointing out that Paulin was "apparently not a biologist, nor is he much read in biological literature... Mr. Paulin himself espouses Lamarckism in the body of his book, though without at any time considering, or even perceiving, the difficulties involved in it."

Worked examples

Example 1 — a first encounter with No Struggle for Existence, No Natural Selection

Start with the simplest possible case. Write down what No Struggle for Existence, No Natural Selection 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 No Struggle for Existence, No Natural Selection 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 No Struggle for Existence, No Natural Selection 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 No Struggle for Existence, No Natural Selection

In research: No Struggle for Existence, No Natural Selection 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 No Struggle for Existence, No Natural Selection 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: No Struggle for Existence, No Natural Selection is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1908 non-fiction books, Books about evolution, Lamarckism, so understanding it makes those chapters shorter.
In everyday life: Look for No Struggle for Existence, No Natural Selection 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.
