A team of evolutionary biologists (phylogeneticists
) sequenced the same gene region from the HIV samples taken from the ex-girlfriend, the patient under the care of the gastroenterologist, and other infected patients in the local general population.
But it continues to be my assessment that the community of phylogeneticists
is excessively worried about lineage sorting, and that sequencing some arbitrarily large number of nuclear genes for some arbitrarily large sample of specimens is scientifically unnecessary and economically undesirable.
Of equal interest to both population biologists and phylogeneticists
is the article by Hey, which presents methods of using gene trees from multiple loci to study recent speciation events.
Reviews of the fossil records of individual flowering plant families are becoming more commonplace as phylogeneticists
seek this information for dating purposes (e.g.
Pinnid species are a challenging group for taxonomists and phylogeneticists
because of the phenotypic plasticity of their shells.
This meeting is meant to start a continuing conversation among a variety of investigators--microbiologists, biogeochemists, ecosystem experts, molecular phylogeneticists
, and molecular ecologists--who are united by their interest in complex microbial processes on Earth.
In addition, phylogeneticists
have yet to undertake an analysis of free-living groups to determine what constitutes "usual" levels of evolutionary loss, beyond noting that some groups appear to exhibit more derived character loss than others (e.g., osmeroid fishes: Begle, 1991).
