Q. Scientists recently have proposed a reorganization of the phylogenetic system of classification to include the domain, a new taxonomic category higher (more inclusive) than the Kingdom category.
explain how this classification scheme presents different conclusions about the relationships among living organisms than those presented by the previous five-kingdom system of classification.
illustrate three kinds of evidence that were used to develop the taxonomic scheme above, and explain how this evidence was used. The evidence may be structural, physiological, molecular, and genetic.
explain four of the characteristics of the universal ancestor.
