Feathers are complex skin structures, and their evolutionary beginnings are still a subject of scientific debate. Scientific evidence points to feathers evolv ...

The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time observation of the chick embryo's development from laying to hatching. The study is published ...

This involved injecting chicken embryos with a molecule that inhibits the Shh pathway – and by day nine of embryonic development, something unusual was beginning to occur. Instead of the ...

which were present in certain dinosaurs.By studying embryonic development of the chicken, researchers from the University of Geneva (UNIGE) have uncovered a key role of a molecular signalling ...

Studying how neural crest cells journey through the embryo, this Caltech developmental biologist has revealed how they form major cell types, including peripheral neurons, bone, and smooth muscle. In ...

A primary step in reaching this conclusion occurred when researchers exposed chick jaws to certain proteins known to cue tooth development. As a result, toothlike structures grew, and other tooth ...
