The paper identifies conserved non-coding elements associated with the evolutionary loss of digit 1 in mammals, showing accelerated evolution and loss of transcription factor binding sites.

The paper shows that cloacal endoderm in mouse embryos differentiates into a transient epidermis in the perineum, which is later replaced by ectoderm.

This study shows that Tfap2a and Tfap2b have tissue-specific roles in tooth development, with epithelial expression critical for incisor morphology and mesenchymal expression having little effect.

This study identifies conserved developmental signaling networks in cuttlefish limbs, showing parallel activation of an ancient genetic program for appendage development.
