Natural selection and phylogenetic analysis.

I f Darwin were to survey the entirety of the biological sciences today, he would be pleased to observe how central phylogenies and ‘‘tree thinking’’ are to integrative research (1). Biologists of all stripes now realize that phylogenies are not exotic, but fundamental and routine tools for understanding not only history but mechanism, organization, and function of biological networks at all le...

Phylogenetic Window Analysis for Detecting Chronological Changes in Natural Selection

Natural selection operating at the amino acid sequence level can be detected by comparing the rates of synonymous (rS) and nonsynonymous (rN) substitutions for the protein-coding nucleotide sequence, where relationships rN > rS and rN < rS conventionally indicate positive and negative selection, respectively. The direction and magnitude of natural selection operating on a protein may change dur...

Natural Language and Natural Selection

Many people have argued that the evolution of the human language faculty cannot be explained by Darwinian natural selection. Chomsky and Gould have suggested that language may have evolved as the by-product of selection for other abilities or as a consequence of as-yet unknown laws of growth and form. Others have argued that a biological specialization for grammar is incompatible with every ten...

Workflows with Model Selection: A Multilocus Approach to Phylogenetic Analysis

The workflow model of description and execution of complex tasks can be of great use to design and parallelize scientific experiments, though it remains a scarcely studied area in its application to phylogenetic analysis. In order to remedy this situation, we study and identify sources of parallel tasks in the main reconstruction stages as well as in other indispensable problems on which it dep...

Prevalence and phylogenetic analysis of Theileria equi in Iranian dromedaries

Considering the importance of Theileria equi infection in horse breeding industry and marketing, in the present study, we aimed to determine the prevalence of T. equi among dromedaries in central Iran, where a considerable number of camels and horses are raised and equine theileriosis is quite prevalent. For this purpose, a total of 161 blood samples from camels were examined in terms of T. equ...
