In the last few weeks we have disected a lot of animals from all diffrent kingdoms and a lot of them are the complete opposite from each other. For example the frog which had like 3 hearts and the fish that has two chambers, Two hearts. It is very wierd how this animals have multiple hearts but at the same time have many weaknesses. I believe that this animals have alot of complexe organs and systems inside them. But i still dont understand how even though they are from diffrent kingdom and like a diffrent species they still have similarities. Maybe the idea that they are living organsims can back it up as a reasonable supporting idea. I dont know but like a lot of these animals had gills which helped the animals breath and also some of this animals didnt have big lungs so they had to breath through its skin.
