ENZYME VARIABILITY IN THE <i>DROSOPHILA WILLISTONI</i> GROUP. IV. GENIC VARIATION IN NATURAL POPULATIONS OF <i>DROSOPHILA WILLISTONI</i>

Global Models of Growth and Competition

A clonal theory of parasitic protozoa: the population structures of Entamoeba, Giardia, Leishmania, Naegleria, Plasmodium, Trichomonas, and Trypanosoma and their medical and taxonomical consequences.

Studies in the Philosophy of Biology

Pseudogenes: Are They “Junk” or Functional DNA?

Frequency-Dependent Selection

Evolutionary and geographical history of the <i>Leishmania donovani</i> complex with a revision of current taxonomy

Natural populations of Trypanosoma cruzi, the agent of Chagas disease, have a complex multiclonal structure.

Teleological Explanations in Evolutionary Biology

Chromosome speciation: Humans,<i>Drosophila</i>, and mosquitoes

Origin of the metazoan phyla: Molecular clocks confirm paleontological estimates

Nucleotide sequences provide evidence of genetic exchange among distantly related lineages of <i>Trypanosoma cruzi</i>
