Gorilla–human last common ancestor

Gorilla–human last common ancestor 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 Gorilla–human last common ancestor rather than just read about it. In short: The gorilla–human last common ancestor (GHLCA, GLCA, or G/H LCA) is the last species that the tribes Hominini and Gorillini (i.e. the chimpanzee–human last common ancestor on one hand and gorillas on the other) share as a common ancestor. It is estimated to have lived 8 to 10 million years ago (TGHLCA) during the late Miocene.

Key takeaways

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

Reference excerpt

The gorilla–human last common ancestor (GHLCA, GLCA, or G/H LCA) is the last species that the tribes Hominini and Gorillini (i.e. the chimpanzee–human last common ancestor on one hand and gorillas on the other) share as a common ancestor. It is estimated to have lived 8 to 10 million years ago (TGHLCA) during the late Miocene. The fossil find of Nakalipithecus nakayamai are closest in age to the GHLCA. The GHLCA marks a pivotal evolutionary split within the Homininae subfamily, separating the lineage that led to gorillas (Gorilla gorilla and Gorilla beringei) from the lineage that eventually gave rise to chimpanzees, bonobos and humans. This ancestor is part of the larger African ape lineage, which also includes the chimpanzee—human last common ancestor (Pan and Homo genera). The divergence of the gorilla lineage likely coincided with significant environmental changes, such as the shrinking of tropical forests during the Miocene. Based on genomic analysis, this ancestor lived around 10 million years ago.

Worked examples

Example 1 — a first encounter with Gorilla–human last common ancestor

Start with the simplest possible case. Write down what Gorilla–human last common ancestor 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 Gorilla–human last common ancestor 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 Gorilla–human last common ancestor 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 Gorilla–human last common ancestor

In research: Gorilla–human last common ancestor 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 Gorilla–human last common ancestor 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: Gorilla–human last common ancestor is common in secondary-school and first-year university syllabi. It links to neighbouring topics Homininae, Human evolution, Most recent common ancestors, so understanding it makes those chapters shorter.
In everyday life: Look for Gorilla–human last common ancestor 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.
