Biology

The broad study of living things, from cells to ecosystems.

Content last reviewed: August 2026

Biology covers life at every scale, molecules and cells, organisms, and ecosystems, giving you a broad scientific foundation before most programs let you specialize (molecular biology, ecology, physiology) in upper-level electives. It's one of the most flexible science majors, feeding into everything from research to health professions to environmental work.

Lab courses run alongside lecture from day one, and many programs expect or encourage undergraduate research experience, working in a faculty lab, by junior or senior year.

Typical courses you might take

  • General Biology I & II
  • General Chemistry
  • Organic Chemistry
  • Genetics
  • Cell Biology
  • Ecology & Evolution
  • Physiology
  • Undergraduate Research or Capstone

How is Biology different from Biochemistry?

They're related but distinct. Biology: The broad study of living things, from cells to ecosystems. Biochemistry: The chemistry of life: molecules, reactions, and cellular processes. Use the compare tool to see courses and skills side by side.

How long does it take to earn a Biology degree?

Most bachelor's degrees, including this one, are designed to be completed in about four years of full-time study. Exact timing depends on your school, course load, transfer credit, and any changes of major along the way.
