The primary idea of this website is to compare human anatomy to those of sea stars and grasshoppers and acquire knowledge about their diversity and how they compare to each other. Each of the organisms that we are comparing have very distinctive functions but they do have similiarities that you will learn along the way! Human body systems as well as organs and general characteristics distinguish what Kingdom organisms are in, and learning the facts about each of them individually can explain why. When you compare organisms there a lot of factors you have to take into consideration but the most studied factor is their bone structure to determine what Kingdom they resemble most. They may seem incomparable on the outside but the similarities between their external and internal systems show us how alike they really are.
