The timing of eukaryotic evolution: does a relaxed molecular clock reconcile proteins and fossils? (2007)

Douzery, Emmanuel J P, Snell, Elizabeth A, Bapteste, Eric, Delsuc, Frédéric, Philippe, Hervé

The use of nucleotide and amino acid sequences allows improved understanding of the timing of evolutionary events of life on earth. Molecular estimates of divergence times are, however, controversial...

Evolution of rhodopsin ion pumps in haloarchaea (2007)

Sharma, Adrian K, Walsh, David A, Bapteste, Eric, Rodriguez-Valera, Francisco, Ford Doolittle, W, Papke, R Thane

Abstract Background The type 1 (microbial) rhodopsins are a diverse group of photochemically reactive proteins that display a broad yet patchy distribution among the three domains of life. Recent...

Refuting phylogenetic relationships (2006)

Bucknam, James, Boucher, Yan, Bapteste, Eric

Abstract Background Phylogenetic methods are philosophically grounded, and so can be philosophically biased in ways that limit explanatory power. This constitutes an important methodologic dimension...

The two tempos of nuclear pore complex evolution: highly adapting proteins in an ancient frozen structure (2005)

Bapteste, Eric, Charlebois, Robert L, MacLeod, Dave, Brochier, Céline

Abstract Background The origin of the nuclear compartment has been extensively debated, leading to several alternative views on the evolution of the eukaryotic nucleus. Until recently, too little...

Deduction of probable events of lateral gene transfer through comparison of phylogenetic trees by recursive consolidation and rearrangement (2005)

MacLeod, Dave, Charlebois, Robert L, Doolittle, Ford, Bapteste, Eric

Abstract Background When organismal phylogenies based on sequences of single marker genes are poorly resolved, a logical approach is to add more markers, on the assumption that weak but congruent...

The analysis of 100 genes supports the grouping of three highly divergent amoebae: Dictyostelium, Entamoeba, and Mastigamoeba

Bapteste, Eric, Brinkmann, Henner, Lee, Jennifer A., Moore, Dorothy V., Sensen, Christoph W., Gordon, Paul, ...

The phylogenetic relationships of amoebae are poorly resolved. To address this difficult question, we have sequenced 1,280 expressed sequence tags from Mastigamoeba balamuthi and assembled a large...

The two tempos of nuclear pore complex evolution: highly adapting proteins in an ancient frozen structure

Bapteste, Eric, Charlebois, Robert L, MacLeod, Dave, Brochier, Céline

An analysis of the taxonomic distribution, evolutionary rates and phylogenies of 65 proteins related to the nuclear pore complex shows high heterogeneity of evolutionary rates between these proteins.

Pattern pluralism and the Tree of Life hypothesis

Doolittle, W. Ford, Bapteste, Eric

Darwin claimed that a unique inclusively hierarchical pattern of relationships between all organisms based on their similarities and differences [the Tree of Life (TOL)] was a fact of nature, for...
