Biology is the science of life — and the questions it asks reach from the inner workings of a single cell all the way out to the ecosystems that span the planet. This page is the central hub for the Biology Contest library: 25 articles, organized into six subtopic clusters, with sub-pillar pages that go deeper on each one.
Six topic clusters#
Pick the thread that fits your curiosity. Each cluster has its own sub-pillar page that goes deeper on the subject and links every article in it.
DNA, the genes that ride it, and the modern tools — CRISPR, gene editing, gene therapy — that let us read and rewrite the code of life.
How living things interact with each other and the planet — ecosystems, biodiversity, marine biology, climate change, and the great extinctions.
Life's smallest units — cell biology, mitosis and meiosis, the microbial world, viruses, and the gut microbiome you carry around with you.
The biology you live inside — major organ systems, the brain and memory, the science of aging, and the DNA driving it all.
The long story of life on Earth — natural selection, the evolution of life, mass extinctions, and the photosynthesis that made all of it possible.
Resources for the biology learner — common myths debunked, home experiments, careers in biology, contest strategies, and the field's Nobel laureates.

Where to start#
Start with What Is Biology? for orientation, then From Cells to Superorganisms for the foundations.
CRISPR and Genetic Engineering cover the biotechnology you're reading headlines about.
Try Climate Change, Biodiversity Hotspots, and Mass Extinctions.
Natural Selection Explained and The Evolution of Life cover biology's central organizing idea.

Biology Mass Extinctions: Life's Great Resets
Five times in Earth's history, the majority of all living species have been wiped out in a geologically brief moment. Mass extinctions reshape the biosphere — and recovery from them looks different every time. A guide to the Big Five, what caused them, and why some scientists think we're in the middle of a sixth.

Biology Mitosis and Meiosis: How Cells Divide
Mitosis copies a cell. Meiosis halves it. The two kinds of cell division do completely different jobs in your body — one builds and repairs, the other makes the eggs and sperm that pass DNA to the next generation. A plain-English walkthrough of how each one works.

Biology Natural Selection Explained: How Species Change
Natural selection is the mechanism Darwin proposed to explain how species change over time — and it remains the central organizing idea of all modern biology. A walkthrough of what it actually is, what it isn't, and how it works in real populations today.

Biology The Brain and How Memory Works
Memory is one of the central mysteries of biology — how a network of cells in your skull stores experience and lets you call it back. A walkthrough of the major types of memory, the brain regions that handle them, and what current neuroscience knows about how it all actually works.

Biology The Gut Microbiome: Your Inner Ecosystem
You're carrying around about 38 trillion microbes — roughly the same number as cells in your own body. They live mostly in your gut, and they do real work on your behalf every day. A guide to the gut microbiome and why it matters.
