Evidence for Evolution of Life

The Evidence for Evolution of Life

Summary:

This video summarizes Charles Darwin's voyage and the explanation behind some of this theories and ideas. It goes through the different pieces of evidence, such as: the size of the beaks of the finches, or that each island had its own climate, that ultimately allowed Darwin to publish his theory of evolution and natural selection in his book, The Origin of Species. It also talks about artificial selection and the use of fossils to make inferences and predictions about the past. Then at the end, it talks about DNA and how DNA can be used to discover the complete past of the Earth.

Relevance to class:

This unit was called,"Evolution."  At the very beginning of the unit, we learned about natural selection and adaptations that allow organisms and species to thrive. We used Darwin's example and we went through how exactly he could come to that examples. We also learned about whales and how through fossils and phylogenetic trees, he can conclude that whales have evolved from land dwelling mammals. This video explains much of what we have went over in class and what we learned in the textbook, specifically chapter 14. It thoroughly explains the discoveries of Darwin and the evidence he used to find it. It also talks about fossils and how they can be used to analyze evolution.
