Key takeaways

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

Reference excerpt

Hamish Gordon Spencer is a New Zealand evolutionary biologist, and is a Distinguished Professor at the University of Otago. Spencer was elected a Fellow of the Royal Society Te Apārangi in 2009, and is a Fellow of the International Science Council. He won the Callaghan Medal in 2016.

Academic career Spencer completed a PhD at Harvard University in 1988, under the supervision of Richard Lewontin. Spencer joined the faculty of the Department of Zoology at the University of Otago in 1992, rising to full professor in 2006. He was appointed one of seven University of Otago Sesquicentennial Distinguished Chairs in 2019. Spencer was director of the Allan Wilson Centre of Research Excellence for three years from 2012. He was an independent science advisor to the Ministry of Business, Innovation and Employment for five years, beginning in 2016. Spencer led the bid to hold the International Congress of History of Science and Technology in New Zealand in 2025. Spencer is an evolutionary biologist, who uses mathematical models and genetics to explore the evolution and diversity of organisms, particularly New Zealand biota. He has worked on frequency-dependent selection and evolutionary developmental biology, and is an expert on New Zealand's molluscan fauna. He is also interested in the history of science, and has written about the history of eugenics and society's attitudes to cousin marriage. Notable students of Spencer include Jemma Geoghegan.

Honours and awards Spencer was elected a Fellow of the Royal Society Te Apārangi in 2009. In 2016 he was awarded the Royal Society's Callaghan Medal, for ''bringing ecological science into the marae and community''. In 2022 he was awarded a James Cook Research Fellowship. He has been a Fellow of the International Science Council since 2023. The deepwater snail Hortia spenceri is named after Spencer.

Personal life Spencer is married to marine biogeochemist Abigail Smith.

Worked examples

Example 1 — a first encounter with Hamish Spencer

Start with the simplest possible case. Write down what Hamish Spencer 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 Hamish Spencer 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 Hamish Spencer 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 Hamish Spencer

In research: Hamish Spencer 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 Hamish Spencer 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: Hamish Spencer is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of the University of Otago, Evolutionary biologists, Fellows of the Royal Society of New Zealand, so understanding it makes those chapters shorter.
In everyday life: Look for Hamish Spencer 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.
