Rollulinae

Rollulinae is a science 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 Rollulinae rather than just read about it. In short: Rollulinae is a bird subfamily containing the jungle and wood partridges. They are sister to all other members of the family Phasianidae, having diverged during the late Eocene or early Oligocene, about 30-35 million years ago.

Key takeaways

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

Reference excerpt

Rollulinae is a bird subfamily containing the jungle and wood partridges. They are sister to all other members of the family Phasianidae, having diverged during the late Eocene or early Oligocene, about 30-35 million years ago. Many taxonomists formerly placed this subfamily within the Perdicinae, but more recent studies have affirmed its existence, and it is accepted by taxonomic authorities such as the International Ornithological Congress. Members of this family are mostly found in east and southeast Asia, but a single genus, which is sister to all other genera in the family, contains two species endemic to two mountain ranges in Tanzania.

Worked examples

Example 1 — a first encounter with Rollulinae

Start with the simplest possible case. Write down what Rollulinae claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Rollulinae 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 Rollulinae 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 Rollulinae

In research: Rollulinae appears in science 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 Rollulinae 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: Rollulinae is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bird subfamilies, Galliformes stubs, Rollulinae, so understanding it makes those chapters shorter.
In everyday life: Look for Rollulinae 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.

Frequently asked questions

What is Rollulinae in simple terms?

Why does Rollulinae matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Rollulinae?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
