IN recasting his excellent text-book of vertebrate embryology for a third edition, Prof. Waldo Shumway has incorporated much new material, especially summarising the results of recent experimental ...

Scientists reveal clues about the evolutionary origin of jaws by studying the embryonic development of zebrafish -- an approach known as 'evo-devo.' Using imaging and cell tracing techniques in ...

THE publication of this imposing volume suggests a consideration of the more important resources already available. For the older literature, that is, up to 1776, we must still rely on Haller's ...

Reviewed Work: An Introduction to the Literature of Vertebrate Zoology Based Chiefly on the Titles in the Blacker Library of Zoology, the Emma Shearer Wood Library of Ornithology, the Bibliotheca ...

Researchers have elucidated the evolutionary origins of placodes and neural crests, which are defining features of vertebrates, through lineage tracing and genetic analysis in Ciona intestinalis, a ...
