Evolution vs Adaptation: What’s the Difference?

The difference at a glance

Evolution is the overall process of change in species over generations. Adaptation is a specific feature that helps an organism survive within that evolution.

What does Evolution mean?

noun · /ˌɛv.əˈluː.ʃən/

The gradual development of something; in biology, the process by which different organisms develop from earlier forms through natural selection operating on heritable variation. Evolution is change over time — not towards perfection, but towards fit.

Evolution in a sentence

Evolution is not progress toward a goal. It is adaptation to conditions — and conditions change.

The evolution of language mirrors biological evolution: variation, selection, inheritance, drift.

What does Adaptation mean?

noun · /ˌæd.æpˈteɪ.ʃən/

The process of change by which an organism or species becomes better suited to its environment over time. Also: a cultural work adapted from another medium. Adaptation is the principle that change is not loss but fitting — the organism and its world coming into better alignment.

Adaptation in a sentence
