Evolution
Storyboard Text
- I'm going to be explaining the use of comparative anatomy and comparative embryology in order to define and explain the evidence used for evolution. Evolution is the change of species over many generations of existence.
- 1. Title and Introduction
- Comparative anatomy is the study of similarities and differences in the anatomy of species. The use of comparing organisms determines their evolutionary relationships.
- 2. Evidence 1Explain
- 1. Organisms that share similar features are assumed to be related closely in evolutionary chains and may share common ancestors.
- 3. Evidence 1(continued) explain
- 2. A common example of comparative anatomy is through the forelimb bones of humans, dogs, bats and whales. This is a great collection of evidence to see how different species have evolved from what scientists may believe are common ancestors.
- Comparative embryology compares and contrasts the embryos of different species in order to observe close relationships.
- 4. Evidence 2Explain
- 5. Evidence 2(Continued) Explain
- As a result of comparative embryology, scientists are able to use the information from embryos in order to find common ancestors through the similarities and differences. For example, scientists are able to observe if a species is an invertebrate or not

- 6. Bibliographyand Conclusion
- In conclusion, the use of comparative anatomy and comparative embryology are great sources of evidence for evolution which we now know is the change in species over many generations.
