The embryo defines the primordial developmental stage of multicellular organisms, from
fertilization of the zygote to the formation of tissue layers and organs. Animal zoologists …

Animal and plant development starts with a constituting phase called embryogenesis, which
evolved independently in both lineages. Comparative anatomy of vertebrate development …

The developmental hourglass model has been used to describe the morphological
transitions of related species throughout embryogenesis. Recently, quantifiable approaches …

developmental hourglass patterns are associated with embryogenesis and post-embryonic …

At the molecular level, multicellular eukaryotic lineages and bacterial biofilms show
predictable evolutionary footprints in their development. For instance, the zygotic …

Complex multicellularity has emerged independently across a few eukaryotic lineages and
is often associated with the rise of elaborate, tightly coordinated developmental processes …

The historic developmental hourglass concept depicts the convergence of animal embryos
to a common form during the phylotypic period. Recently, it has been shown that a …

Embryogenesis is the process of transformation of a single fertilized egg into a differentiated,
complex organism. This requires coordinated cleavage of the fertilized egg, followed by …
