95%+ of organisms fit nicely into a nested hierarchy. However, the hierarchy can not fully model that last <5% because there will be shared features/genes with other not closely grouped organisms.
Can you provide an example or two of organisms in this last 5%?
I already provided one. Bats and dolphins.
That bats and dolphins both emply echo-location does not break the model of a nested hierarchy.
A nested hierarchy does not imply that there will not be shared features between the nests.
Like, bugs and birds both have wings but they're not nested together. Or do you think that breaks the model too?
