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 ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...

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 ...

Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late ...

Researchers have developed a theoretical framework that can reproduce and predict the patterns associated with gastrulation in a chicken embryo. Gastrulation is one of the most important phases in ...

Feathers are among the most complex cutaneous appendages in the animal kingdom. While their evolutionary origin has been widely debated, paleontological discoveries and developmental biology studies ...

New research combines microscope and video technology to analyze how different species develop, and how changes in the timings of any developments can be tracked. A detailed analysis of the Energy ...

Like all complex organisms, every human originates from a single cell that multiplies through countless cell divisions. Thousands of cells coordinate, move and exert mechanical forces on each other as ...

Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely ...

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 ...

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 ...

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 ...
