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.

🧠
What Is Biology?
Plain-English orientation to the field.
🌿
Branches of Biology
How biology divides itself into specialties.
📖
Biology Glossary
Quick reference for biology vocabulary.

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.

🧬 Genetics & Biotechnology

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.

4 articles →
🌱 Ecology & the Environment

How living things interact with each other and the planet — ecosystems, biodiversity, marine biology, climate change, and the great extinctions.

5 articles →
🧫 Cells & Microorganisms

Life's smallest units — cell biology, mitosis and meiosis, the microbial world, viruses, and the gut microbiome you carry around with you.

5 articles →
🫁 The Human Body

The biology you live inside — major organ systems, the brain and memory, the science of aging, and the DNA driving it all.

4 articles →
🦴 Evolution & Plant Life

The long story of life on Earth — natural selection, the evolution of life, mass extinctions, and the photosynthesis that made all of it possible.

4 articles →
🎯 Learning & Practice

Resources for the biology learner — common myths debunked, home experiments, careers in biology, contest strategies, and the field's Nobel laureates.
