TL;DR
These results provide an independent confirmation of relationships proposed in both the morphological and molecular studiesthat New World barbets and toucans are sister taxa with respect to Old World barbet taxa.
Abstract
An 888-base-pair segment of the mitochondrial cytochrome-b gene was sequenced for New World barbets, Old World barbets, toucans, and several outgroup taxa. Toucans were consistently identified as the sister taxon of the New World barbets by a variety of analyses. These data are fundamentally different from earlier morphological analyses and the DNA-DNA hybridization study of these same taxa. Our results provide an independent confirmation of relationships proposed in both the morphological and molecular studies-that New World barbets and toucans are sister taxa with respect to Old World barbets.

The complete sequence of the 16,569-base pair human mitochondrial genome is presented and shows extreme economy in that the genes have none or only a few noncoding bases between them, and in many cases the termination codons are not coded in the DNA but are created post-transcriptionally by polyadenylation of the mRNAs.

Comparisons of these cytochromeb sequences support current structure-function models for this membrane-spanning protein, including that part of the outer surface which includes the Qo redox center is more constrained than the remainder of the molecule, namely, the transmembrane segments and the surface that protrudes into the mitochondrial matrix.

The method of evolutionary parsimony accurately predicts the tree, even when substitution rates differ greatly in neighboring peripheral branches (conditions under which parsimony will consistently fail), as the number of substitutions in peripheral branches becomes fewer, the parsimony and the evolutionary-parsimony solutions converge.

The mitochondrial tree shows broad concordance with that based on hybridization of nuclear DNA; however, parsimony and maximum likelihood methods suggest a close kinship between thrushes and Australian babblers, in agreement with the traditional morphological classification.

A jackknife technique is presented that identifies those portions of evolutionary history that are poorly known due to inconsistencies in the data that more accurately represent the results of a study than do current tree-generating algorithms that obscure areas of uncertainty.

It is concluded that the DNA hybridization approach remains the best and most cost‐effective guide to phylogenetic relationships over its useful range, and serious flaws in certain recent attempts to apply the method to specific cases among primates and birds are demonstrated.

High levels of base-substitutional divergence were detected within and between northern and southern lineages of P. temporalis, which implies a low level of gene flow between northernand southern regions as well as a low rate of length mutation.

The HLmt-17.8 mtDNA-like region appears to be a pseudogene that transferred into the nucleus in humans more recently than nine million years ago and was found in the DNAs of human placenta, freshly isolated human leukocytes, foreskin and several human cell lines; but it was not present in other primates or lower organisms.

The most parsimonious morphological phylogeny required fewer character changes and had a lower consistency index than any of the alternative hypotheses but congruence between the most Parsimonious phylogeny and the second, revised DNA-DNA hybridization hypothesis was very high.
