Embryonic development is a finely orchestrated process in which a single cell differentiates into the myriad specialised tissues that comprise a fully formed organism. Central to this process are ...

Amphioxus, as a basal chordate, offers an insightful window into the evolutionary origins of vertebrate development. Its embryogenesis, characterised by the formation of a notochord, neural tube and ...

Small fold – big role: A tissue fold known as the cephalic furrow, an evolutionary novelty that forms between the head and the trunk of fly embryos, plays a mechanical role in stabilizing embryonic ...

Although the phrase "what came first, the chicken or the egg" at first appears paradoxical, science confirms that the egg maintains temporal supremacy. However, a new study from the University of ...

Feathers are important for birds today, enabling flight, warmth, and communication. Now, researchers from the University of Geneva have traced the origin of feathers. Scientists believe feathers ...

Introduction : The modularity concept in developmental and evolutionary biology / Gerhard Schlosser and Günter P. Wagner -- Selector genes and the genetic control of developmental modules / Craig ...

Have you ever looked at a human embryo and thought, “That kind of looks like a fish”? If you haven’t, you might be surprised to learn that, in a way, we all begin our lives like this. The idea that ...

Add Yahoo as a preferred source to see more of our stories on Google. As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of species over the course of ...

Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...
