Biology Unit 5 Study Guide: Evolution. After his visit to the Galapagos Islands, Darwin came up with the theory of evolution. This theory stated that organisms change over time. The way that organisms change is through the process of natural selection. With examples, practice questions, and answers to help make evolution respiration easy to learn!
How did flightless birds evolve? How did the evolution of the shrinking cod come to be? In this lesson, we learn about the evolution of the flightless birds, such as cormorants, and the evolution of the shrinking cod in our biology selection case studies.
We explore natural selection in action with the evolution of Darwin’s Finches, Peter Grant and Rosemary Grant’s research on the Galapagos Islands
