Reference excerpt

Power, Sex, Suicide: Mitochondria and the Meaning of Life is a 2005 popular science book by the biochemist Nick Lane, in which he argues that mitochondria are central to questions of the evolution of multicellularity, the evolution of sexual reproduction, and to the process of senescence. Amongst the theories advanced in the book, Lane endorses the hydrogen hypothesis for the formation of the eukaryotic cell, whereby mitochondria are the original defining characteristic of the structure. He argues that the event was an exceedingly improbable one and questions the likelihood of its having happened elsewhere in the Universe. He suggests that the necessity for genetic compatibility between mitochondrial and nuclear DNA lies behind the differentiation of sex, ensuring that only one sexual partner contributes mitochondrial DNA to offspring. Steven Rose in The Guardian said that the book contains "one of the most interesting stories modern biology has to tell". It was shortlisted for the Royal Society Science Book Prize in 2006.

Worked examples

Example 1 — a first encounter with Power, Sex, Suicide

Start with the simplest possible case. Write down what Power, Sex, Suicide 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 Power, Sex, Suicide 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 Power, Sex, Suicide 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 Power, Sex, Suicide

In research: Power, Sex, Suicide 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 Power, Sex, Suicide 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: Power, Sex, Suicide is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2005 non-fiction books, Biology book stubs, Books about evolution, so understanding it makes those chapters shorter.
In everyday life: Look for Power, Sex, Suicide 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.
