Summary

The video, “Evidence for Evolution” displays the four primary categories that provide evidence for evolution. This video discusses fossils, anatomical evidence, embryology, and biochemical evidence, and how each provides supportive evidence for evolution. Moreover, the video expands in depth on each of these topics, providing their audience with a detailed understanding of both geological topics, in addition to evolution itself.

Why watch this video?

• Have you ever wondered how fossils are made?
• Would you like to know why there are some parts of humans that appear to have absolutely no practical function?
• Have you ever been confused by the concept of mutations and/or DNA?

Key terms

Anatomical evidence – A type of evidence that compares the similar anatomy of different species to find a matching ancestor.

Embryology – A type of biology that studies the development of embryos.

Biochemical evidence – A type of evidence concerned with DNA and amino acids. The amount of amino acids in a specific species blood determines how closely related they are to another species.

Loose ends

1. The human appendix is mentioned as an example of a vestigial structure. The video states that it does not have a function in the human body, however, they mention afterwards that the appendix does indeed have a function in humans. This is a loose end as it is contradictory to their previous statement and confusing for their viewers.
2. The video briefly mentions radiometric dating but neglects to go into detail about it. This is a point that could have been expanded upon more, as it is a complex topic and directly related to fossil evidence.
3. As an example for embryology, the video uses the example of Haeckel’s exaggerated and inaccurate drawings. However, the video does not provide an actual example of accurate embryology. This topic should have been expanded on further, with more accurate and applicable examples.
