Nucleotide sequences provide evidence of genetic exchange among distantly related lineages of Trypanosoma cruzi
Simple phylogenetic tests were applied to a large data set of nucleotide sequences from two nuclear genes and a region of the mitochondrial genome of Trypanosoma cruzi, the agent of Chagas' disease.Expand

Evidence for positive selection in the superoxide dismutase (Sod) region of Drosophila melanogaster.
DNA sequence variation in a 1410-bp region including the Cu,Zn Sod locus was examined in 41 homozygous lines of Drosophila melanogaster. Fourteen lines were from Barcelona, Spain, 25 were fromExpand

GENETIC DIFFERENTIATION DURING THE SPECIATION PROCESS IN DROSOPHILA
Evolution consists of changes in the genetic constitution (gene pool) of populations. The process of evolution may be seen in two ways-which have been called anagenesis and cladogenesis (Rensch,Expand
