Has anyone built a tree based on a new feature never previously used in its history.
EX. Feathers - all species that have feathers. Was it a dinosaur that feathers developed for the first time or another bird during its origin of feathers.
Skin origin from water to land and every other new variation that ends with human skin currently.
internal specialized organs - We certainly have a wide range of species that do not have all of the specialized organs but still able to perform the same functions. We do have a pattern where many of them still live in the ocean while all land species have all the specialized organs.
If a tree is done in this fashion, I think one could understand how all of the different varieties of species are connected.
