Biology
Zoom from molecules to cells, organisms, populations, and ecosystems. Biology changes its tools as scale changes, while the same living processes keep connecting the whole system.
Biology is a zoom lens on the same living world.
Start at the scale of the system you want to explain. The fields overlap because living systems cross boundaries constantly.
Information & machinery
Genes and biomolecules store instructions, catalyze reactions, and build living structures.
The living unit
Cells organize chemistry into self-maintaining systems; microbes show how much life fits at tiny scales.
Bodies & forms of life
Organisms coordinate structures and functions while fungi, plants, and animals solve survival differently.
Populations & ecosystems
Organisms form populations, communities, food webs, and ecosystems linked by energy and material cycles.
Evolution crosses the whole atlas.
Inheritance begins within organisms, selection acts on populations, and change accumulates across generations. Evolution links every biological scale.
