Richard Dawkins, an English ethologist, evolutionary biologist, and writer of the 21^st century, has said, "You can't even begin to understand biology, you can't understand life, unless you understand what it's all there for, how it arose - and that means evolution." his quote emphasizes the importance of the comprehension of the theory of evolution in the discipline of biology. Living beings may seem diverse, but under the eyes of evolution, every living being comes from a common ancestor. Therefore, all species in the planet Earth are related. Thanks to the discovery of DNA and the technological advances being made in molecular genetics, we know that all organisms share the same four nitrogen bases which codifies within the same 20 amino acids: the difference is just the sequence. The evolutionary theory explains relationships between organisms by common ancestry. With all this knowledge, it's imperative to understand the foundation and what supports this theory.

This lesson contains three learning activities to achieve the learning objective. The first activity is a bell work that consist of three questions to assess prior knowledge of the students in diversity and evolution. The second activity is a collaborative research for each category that supports evolution. The last activity is the completion of notes taken by each student to ensure understanding and comprehension for every piece of evidence.
