Imagine a world where the boundaries between “fish” and “not-fish” blur, where the ancestors of birds and mammals once swam ...

The key to understanding vertebrate development and the origins of human birth defects may lie with the fishes--that is, with the zebrafishes (Danio rerio). Using zebrafish mutants produced primarily ...

In 1969, Karten wrote a “very influential paper that completely changed the discussion in the field,” said Maria Tosches, who studies vertebrate brain development at Columbia University. “His work was ...

All vertebrate embryos follow a common developmental ... embryos as adults become more and more apparent. The study of this development can yield insights into the process of evolution.

in vertebrates (including humans), the various parts of the skeleton arise from different groups of precursor cells during embryonic development. During this process, each group produces its own ...

Research in our group investigates a number of questions central to understanding animal evolution and development: What determines the ... morphological diversity of organs and tissues across ...

A comparative study of vertebrate embryological development focusing on the morphological development (e.g., Differentiation of tissues, organs, and systems) of vertebrates. Evolutionary relationships ...

In vertebrates, segmentation results in the development of the spine, head, and limbs; in insects, it results in formation of the abdomen, head, and thorax. Segmentation is believed to be the ...

Analytical and experimental techniques used to explore invertebrate and vertebrate development include embryological manipulation, molecular and cell biology approaches. Conceptual topics include cell ...

Our project investigates how the remarkable variation in head morphology across vertebrates—especially among reptiles ... and cellular dynamics that drive craniofacial development. Our goal is to ...
