Key takeaways

Life on Our Planet belongs to astronomy; place it in that map before memorising details.

Connect Life on Our Planet to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Life on Our Planet from memory before moving on to harder problems.

Reference excerpt

Life on Our Planet is an American television nature documentary miniseries released on Netflix and produced by Amblin Television and Silverback Films. Executive-produced by Steven Spielberg and narrated by Morgan Freeman, the series focuses on the evolutionary history of complex life on Earth. Upon its release, the series received generally mixed reviews, with praise for its visual effects, cinematography, soundtrack and scale, but criticism for its presentation, format, and script. In March 2026, its spiritual successor, The Dinosaurs, was released on Netflix.

Development and release Netflix first announced the series on November 1, 2022. Silverback Films and Amblin Television serve as the series' production companies. Steven Spielberg is listed as executive producer on the series. Morgan Freeman serves as the series' narrator. A teaser for the series was released on YouTube by Netflix on August 22, 2023, while the official trailer was released on September 26. The series consists of eight episodes and was released on October 25, 2023. The series includes a hybrid of both computer-generated imagery (CGI) and live footage videography. A tie-in book written by Fletcher 2023 was published by Witness Books.

Episodes Each episode focuses on a specific few geologic periods, including the geologic and ecological changes that occurred during them (largely visualized with live-action footage as proxies, with some rendered imagery) and the prehistoric life that lived during those periods, which are visualized in photorealistic CGI akin to the Walking with... series and Prehistoric Planet. Each episode also features modern taxa that can trace their ancestry back to the geologic time periods shown, with several live-action segments akin to traditional nature documentaries, showing footage of some of the unique modern adaptations that some of these taxa have evolved.

Reception The review aggregator website Rotten Tomatoes reported a 50% approval rating with an average rating of 4.7/10, based on 6 reviews. On Metacritic, the series has a weighted average score of 55 out of 100, based on 5 reviews, indicating "mixed or average". Jack Seale of The Guardian praised the series' cinematography and visual effects with some exceptions, noting that "footage of animals that are real (...) and sequences conjured from scratch on a computer are nearly indistinguishable". However, criticism was given for the script and Freeman's narration, which he described as hyperbolic and treating "billions of animals in the same broad biological grouping as if they were an army or a sports team enjoying success together", ultimately describing the series as "empty spectacle". Biologists Tim Rock and Matthew Wills of The Conversation gave a more positive review, praising the series for its ambition and referring to it as "hugely entertaining", although it was accused of occasionally adopting adaptationism for its narrative. The series was nominated for International Green Film Award at the Cinema for Peace awards in 2024.

Worked examples

Example 1 — a first encounter with Life on Our Planet

Start with the simplest possible case. Write down what Life on Our Planet 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 Life on Our Planet 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 Life on Our Planet 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 Life on Our Planet

In research: Life on Our Planet 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 Life on Our Planet 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: Life on Our Planet is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2020s American documentary television series, 2023 American television series debuts, 2023 American television series endings, so understanding it makes those chapters shorter.
In everyday life: Look for Life on Our Planet 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.
