TL;DR: The distribution of syntenic blocks, evolutionary breakpoint regions, and evolutionary breakpoints taken from public databases available for seven eutherian species and the chicken are analyzed for correspondence with human fragile sites and tandem repeats to provide further evidence that certain chromosomes in the human genome have been repeatedly used in the evolutionary process.

TL;DR: Thermal denaturation in D2O buffer shows a decrease in nonstructured conformations and an increase in beta-turns without major changes in the proportion of alpha-helix, while temperature-induced changes are not the same in amorphous and crystalline structures.

TL;DR: Using maximum-likelihood phylogenetic trees constructed from a large number of complete or nearly complete mammalian cytochrome b sequences, it is shown that the distributions of intrageneric and intergeneric distances derived from these trees are clearly separated, which allows the limits for a more rational generic classification of mammals to be established.

TL;DR: A phylogenetic analysis of the new protein sequences gives support to the view that an elaborate aerobic respiratory chain was already present in the last common ancestor of all living organisms.

TL;DR: A new phylogenetic comparison method that measures overall differences in the relative branch length and topology of two phylogenetic trees, resulting in the minimum branch length distance or K tree score, which allows the evaluation of the performance of phylogenetic algorithms, not only with respect to their topological accuracy, but also to the reproduction of a given branch length variation.
