Just as life has a history, science has a history. Understanding the history of evolutionary thinking illuminates the nature of science. Four disciplinary areas — Earth's history, life's history, mechanisms of evolution, and development and genetics — has contributed to our current understanding of evolution. This resource is part of the Biology Links for One Laptop Per Child course which contains units on Exploring Life; The Cell; Genetics; Mechanisms of Evolution; The Evolutionary History of Biological Diversity; Plant Form and Function; Animal Form and Function; Ecology; and Astrobiology.

The environment plays a major role in the evolution of species. Learn about the ecological pattern to how species arise and die out and discover how natural selection acts differently on related species living in different habitats.

In this activity, you will find out about research being conducted on some of the most ancient farmers in the world -- Amazon leafcutter ants. Then you will get to be a researcher yourself. You will watch video segments to make your own virtual field observationsand write your own research proposal. Finally, you will attend a simulated research conference to share your ideas with your peers in a poster session. This resource is part of the Biology Links for One Laptop Per Child course which contains units on Exploring Life; The Cell; Genetics; Mechanisms of Evolution; The Evolutionary History of Biological Diversity; Plant Form and Function; Animal Form and Function; Ecology; and Astrobiology.
