TLDR
The neighbor-joining method and Sattath and Tversky's method are shown to be generally better than the other methods for reconstructing phylogenetic trees from evolutionary distance data.Abstract:
A new method called the neighbor-joining method is proposed for reconstructing phylogenetic trees from evolutionary distance data. The principle of this method is to find pairs of operational taxonomic units (OTUs [= neighbors]) that minimize the total branch length at each stage of clustering of OTUs starting with a starlike tree. The branch lengths as well as the topology of a parsimonious tree can quickly be obtained by using this method. Using computer simulation, we studied the efficiency of this method in obtaining the correct unrooted tree in comparison with that of five other tree-making methods: the unweighted pair group method of analysis, Farris's method, Sattath and Tversky's method, Li's method, and Tateno et al.'s modified Farris method. The new, neighbor-joining method and Sattath and Tversky's method are shown to be generally better than the other methods.read more

TL;DR: This report represents the first description of the microbial diversity in Amazonian soils involving a culture-independent approach and rRNA intergenic spacer analysis was used to show significant microbial population differences between a mature forest soil and an adjacent pasture soil.

TL;DR: The structural properties of both classes of soluble proteins, their affinity to small ligands, and their expression in the different parts of the insect body and subcellular localisation are reviewed.

TL;DR: The T2T-CHM13-T2T Consortium presented a complete 3.055 billion-base pair sequence of a human genome, including gapless assemblies for all chromosomes except Y, corrected errors in the prior references, and introduced nearly 200 million base pairs of sequence containing gene predictions, 99 of which are predicted to be protein coding as discussed by the authors .

Genomic Divergences between Humans and Other Hominoids and the Effective Population Size of the Common Ancestor of Humans and Chimpanzees
Feng Chi Chen,Wen-Hsiung Li +1 more
TL;DR: The human lineage apparently had experienced a large reduction in effective population size after its separation from the chimpanzee lineage, suggesting that the gorilla lineage branched off 1.6 to 2.2 million years earlier than did the human-chimpanzee divergence.

Molecular Evolutionary Genetics
TL;DR: Recent developments of statistical methods in molecular phylogenetics are reviewed and it is shown that the mathematical foundations of these methods are not well established, but computer simulations and empirical data indicate that currently used methods produce reasonably good phylogenetic trees when a sufficiently large number of nucleotides or amino acids are used.
