John Crook (ethologist)

John Crook (ethologist) is a astronomy 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 John Crook (ethologist) rather than just read about it. In short: John Hurrell Crook (27 November 1930 – 15 July 2011) was a British ethologist who filled a pivotal role in British primatology. As Reader in Ethology (animal behaviour) in the Psychology Department of University of Bristol, he led a research group studying social and reproductive behaviour in birds and primates throughout the 1970s–80s, turning to the socio-psychological anthropology of Himalayan peoples in the 1990…

Key takeaways

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

Reference excerpt

John Hurrell Crook (27 November 1930 – 15 July 2011) was a British ethologist who filled a pivotal role in British primatology. As Reader in Ethology (animal behaviour) in the Psychology Department of University of Bristol, he led a research group studying social and reproductive behaviour in birds and primates throughout the 1970s–80s, turning to the socio-psychological anthropology of Himalayan peoples in the 1990s. In his later years he was the Teacher of the Western Chan Fellowship.

Early life He was educated at Oakmount School, Southampton and Sherborne School, Dorset. He completed his national service in Hong Kong, where he first encountered Chan Buddhism.

Academic career Crook was a pioneer in the early development of socio-ecology, adding this dimension to ethology which was then dominated by the ideas of "Niko" Tinbergen and Konrad Lorenz. His student paper on the gulls of Southampton Water while at University of Southampton, led to his doctoral study at Jesus College, Cambridge of the weaver birds (Ploceidae) of West Africa, supervised by William Homan Thorpe and Robert Hinde. This was followed by further research in India, the Seychelles Islands and East Africa. His theoretical interpretation subsequently contributed to David Lack's discussion of the behavioural component in avian population research. His fieldwork was further supported by laboratory experimentation on the endocrinal basis for the behaviour observed in the field. After moving to Bristol University, he collaborated with Professor K.R.L. Hall in establishing a centre for primate studies, extending socio-ecological principles to primates, supervising doctoral projects and leading field research in Ethiopia on geladas and in Morocco on the Barbary macaque, subsequently developed by Robin Dunbar and John Deag respectively. His year as Fellow at the Center for Advanced Study in the Behavioral Sciences at Stanford University in California introduced him to the new techniques of humanistic psychotherapy. On return to Bristol, his students requested him to demonstrate these methods, leading to the creation of the Bristol Encounter Centre and to his teaching of the subject widely in the UK, especially based on workshops run at his retreat centre in mid Wales. In 1977, Crook led an expedition to Zanskar in the Himalayas of Ladakh, a pilot study focussing on polyandry. For several years, he and colleagues led further expeditions studying the geology, agriculture, social and family life and monastic practices in this remote, high-altitude region. He later returned with James Low, a Tibetologist fluent in the texts and language, to study the lives of Buddhist hermits in the mountains.

Buddhism Retiring early, Crook began practising Zen Buddhism in intensive retreats taught at Dharma Drum Retreat Center in New York by Chan Master Sheng-yen of Dharma Drum Mountain, Taiwan, who in 1993 transmitted to him the authority to teach Chan Buddhism. Forming the Western Chan Fellowship with colleagues, Crook developed a programme of retreats adapted to Western Zen practitioners. Crook published around a hundred scientific papers in ornithology, ethology and evolutionary psychology, and several books focussing on consciousness and Zen practice. His last work was World Crisis and Buddhist Humanism (New Age Books, Delhi 2009). He died on 15 July 2011, shortly after a gathering of many former students and colleagues in Somerset to celebrate his life. Dr Innes Cuthill, Professor of Behavioural Ecology at Bristol University, described him as "a pivotal figure in the rise of British primatology and socio-ecology".

Worked examples

Example 1 — a first encounter with John Crook (ethologist)

Start with the simplest possible case. Write down what John Crook (ethologist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 John Crook (ethologist) 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 John Crook (ethologist) 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 John Crook (ethologist)

In research
John Crook (ethologist) appears in astronomy 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 John Crook (ethologist) 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
John Crook (ethologist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1930 births, 2011 deaths, Alumni of Jesus College, Cambridge, so understanding it makes those chapters shorter.
In everyday life
Look for John Crook (ethologist) 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.
