What Biology Is
Captions available
The idea
Biology is the science that studies life, from single molecules to the whole living planet.
In practice
A biologist can study one protein inside one cell, or track how a whole forest changes across a century — both are biology.
Where people slip
A student who assumes biology stops at whole organisms, leaving out molecules and ecosystems, misses most of the field's actual scope.
