Chordate Developmental Biology Print E-mail


- Dissections and imaging of the musculo-skeletal system of non-vertebrate groups such as sea squirts and of each major group of vertebrates, including taxa such as skates, zebrafish, turtles, lizards, frogs, salamanders, chicken, marsupials, mice, bats, and primates

- Parallelism between ontogeny and phylogeny

- Analyses of anatomical variants/anomalies: comparative, evolutionary, developmental and genetic perspectives

Chordate Comparative Anatomy Print E-mail



- Dissections and imaging of the musculo-skeletal system of non-vertebrate groups such as sea squirts and of each major group of vertebrates, including taxa such as skates, actinopterygians, dipnoans, turtles, crocodilians, birds, squamates, anurans, caecilians, urodeles, monotremes, marsupials, rodents, bats, flying lemurs, tree-shrews, and primates

- Publications of Tables providing homology hypotheses and a list of synonymies for each muscle of each of these taxa

Birth Defects PDF Print E-mail










 (* picture by, and copyright of, Christopher Smith)










- Dissection of humans with various types of birth defects (e.g., polydactyly or oligodactyly) related with  different types of syndromes (e.g. related to trisomies 13, 18 and 21).

Publication of musculoskeletal atlases of different types of human defects (e.g., polydactyly) in different types  of syndromes (e.g. related to trisomies 13, 18 and 21).

- Study of phenotypic-genotypic correlations and muscle-skeleton spatial associations in human birth defects.

- Study the anatomical development of mouse models for Down Sndrome

- Pave the way to better predict the musculoskeletal phenotype of infants and children with birth defects and  therefore to better evaluate and plan, and improve the effective effectiveness of, surgical treatment of such  defects


Chordate Phylogeny and Evolution Print E-mail

img4 cópia


- Cladistic analyses of the higher-level phylogeny of chordates and of the relationships of various subgroups (e.g., teleosts, ostariophysans, catfish) based on hard-tissue and soft-tissue characters

- Cladistic analyses of various groups (e.g., sturgeons, ostariophysans, teleosts) based on molecular characters

- Muscles vs bones, soft tissues vs hard tissues, and morphology vs molecules in phylogenetic reconstructions

- Homology, homoplasy, convergences, reversions, and anatomical complexity within the evolutionary history of chordates
