Genetics & Evolution
Learn how genetic information is copied, inherited and changed across generations, and how those processes connect to evolution. This section covers DNA replication, heredity, population change and human evolutionary history using evidence from genetics, fossils and comparative biology. Science University aims to explain both the mechanisms and the limits of current evidence, avoiding oversimplified claims. Use this hub to connect molecular genetics with the larger evolutionary processes that generate biological diversity over time.
