The topic of this project was to inform you about the evolutionary process of cephalopods. At the end of evolution, a highly developed species - octopus have appeared.
In order to explain this development process, basic anatomical knowledge of octopus was first needed, and the overall tendency of the shell to disappear were explained.
Now that I have identified the overall trend, numbers 4 and 5 on the right consist of explanations of the family tree, which is a visual hook, and parts that show what has changed or differentiated in each evolutionary process.
