(12) A tree based on inferred amino acid replacements, silent transversions, and ribosomal RNA (rRNA) substitutions showed with statistical confidence that the lungfish mtDNA is more closely related to that of the frog than is the mtDNA of the coelacanth.
(13) Fossils dating from the time of origin of tetrapods in the Devonian offer the only hope of understanding the morphological innovations that led to tetrapods; morphological analysis of the "living fossils," the coelacanth and lungfish, only lends confusion.
(14) Combination with results from manual sequence analysis has given the 247-residue amino acid sequence of coelacanth triose phosphate isomerase in 4 months, by using 100mg of enzyme.
(15) This result appears to rule out the possibility that the coelacanth lineage gave rise to land vertebrates; hence, morphological characters that link the latter two groups are possibly due to convergent evolution or reversals and not to common descent.
(16) Parvalbumins from coelacanth (Latimeria chalumnae) myogen have been isolated by gel filtration of Sephadex G-75 and DEAE-cellulose chromatography.
(17) Thus the primary structure of Latimeria haemoglobin indicates that the coelacanth is the closest living relative of tetrapods.
(18) The pineal complex of the coelacanth, Latimeria chalumnae was studied light and electron microscopically.
(19) When the coelacanth was used as an outgroup, Lissamphibia (living amphibians) and Amniota (amniotes) were found to be statistically significant monophyletic groups.
(20) To study the molecular phylogeny of these taxa, the sequences were compared with 18S rRNA sequences of the Coelacanth Latimeria chalumnae, the frog Xenopus laevis, and humans.
