Document Summary

Fungi: monophyletic groups have this number of ancestors one, these appendages of bats and birds are homologous with our arms wings, two different taxa have similar looking structures that function in similar ways. Its an example of this type of evolution convergent: a subset of organisms within a group that all have the same shared characters are referred to as this, and give this method of classification its name. If different taxa are related to each other and the ancestor to the group is not included in the classification they are referred as this polyphyletic.
