1. Polytene chromosomes as indicators of phylogeny in several species groups of Drosophila

   Polytene chromosome banding patterns have long been used by Drosophila evolutionists to infer degree of relatedness among taxa. Recently, nucleotide sequences have preempted this traditional method. We place the ...

2. Parallel evolution of histophagy in ciliates of the genus Tetrahymena

   Species of Tetrahymena were grouped into three complexes based on morphological and life history traits: the pyriformis complex of microstomatous forms; the patula complex of microstome-macrostome transformers; a...

3. A genomic timescale for the origin of eukaryotes

   Genomic sequence analyses have shown that horizontal gene transfer occurred during the origin of eukaryotes as a consequence of symbiosis. However, details of the timing and number of symbiotic events are uncl...

4. Evolution and phylogeny of insect endogenous retroviruses

   The genome of invertebrates is rich in retroelements which are structurally reminiscent of the retroviruses of vertebrates. Those containing three open reading frames (ORFs), including an env-like gene, may well ...

5. Reinforcement of genetic coherence in a two-locus model

   In order to maintain populations as units of reproduction and thus enable anagenetic evolution, genetic factors must exist which prevent continuing reproductive separation or enhance reproductive contact. This...

6. Relatedness of baculovirus and gypsy retrotransposon envelope proteins

   Current evidence suggests that lepidopteran baculoviruses may be divided into two phylogenetic groups based on their envelope fusion proteins. One group utilizes gp64, a low pH-dependent envelope fusion protei...
