A good way to start learning biology is to begin with a broad introductory course and then choose a focused area that interests you. Courses such as Biology Everywhere, General Biology, and Introduction to Biology: Ecology, Evolution, & Biodiversity can introduce key ideas about life, organisms, ecosystems, and scientific thinking. From there, you might move into genetics, evolution, anatomy, cancer biology, or molecular and cell biology. Coursera’s course selection lets you start with foundational topics and gradually build toward more specialized biology knowledge.‎

Yes. You can start learning biology on Coursera for free in two ways:

1. Preview the first module of many biology courses at no cost. This includes video lessons, readings, graded assignments, and Coursera AI (where available).
2. Start a 7-day free trial for Specializations or Coursera Plus. This gives you full access to all course content across eligible programs within the timeframe of your trial.

If you want to keep learning, earn a certificate in biology, or unlock full course access after the preview or trial, you can upgrade or apply for financial aid.‎

The best beginner biology courses are usually broad, introductory options that explain core concepts before moving into specialized topics. On this page, courses such as General Biology, Biology Everywhere, and Introduction to Biology: Ecology, Evolution, & Biodiversity are good starting points for learners who want a wide foundation. Introduction to Genetics and Evolution may also suit beginners who are especially interested in heredity, adaptation, and evolutionary ideas. After building basics, you can continue with more focused courses such as Anatomy, Cancer Biology, or Molecular and Cell Biology.‎

Biology courses typically cover cells, genes, evolution, ecology, anatomy, biodiversity, organisms, and how living systems function. Some courses focus on broad foundations, while others concentrate on specific areas such as cancer biology, molecular and cell biology, genetics, or evolutionary behavior. The courses listed on this page include topics from ecology and biodiversity to anatomy, genes, cells, and disease processes. Comparing course titles and descriptions on Coursera can help you choose whether to begin with general biology or study a more specialized subject first.‎
