This video explores how Charles Darwin and Alfred Wallace came up with the theory of evolution and process of natural selection. It is set in 1858 and explains the adaptation of plants and animals to their environment. The video covers how they both explored the connection between animals and humans, and asked scientific questions about the origin of plants and animals, where we all came from and how we all came to be. They found that humans shared a common ancestor with chimpanzees. Teacher notes: As a starter to introduce a practical science activity, you could write a simple quiz to encourage students to capture the keywords shown in the video. Students can write their own definitions from these words using the internet or science dictionaries to improve their scientific vocabularies. To consolidate their knowledge, you could get students to make booklets that include key information about Darwin and Wallace. They could define the keywords featured in the video, and find five or more additional pieces of information about the work of the scientists using books, encyclopedias or the internet.
