Abstract Embryos of different species of vertebrate share a common organisation and often look similar. [] Key Result We find that embryos at the tailbud stage – thought to correspond to a conserved stage – show variations in form due to allometry, heterochrony, and differences in body plan and somite number. These variations foreshadow important differences in adult body form.

The results demonstrate that the mid-embryonic stage of the mouse is indeed highly constrained, supporting the existence of the phylotypic stage and highlighting the hierarchical aspect of embryogenesis proposed by von Baer.

It is argued here that differences in adult morphology may be generated at a variety of stages, and the phylotypic stage, the developmental hourglass, modularity, and von Baerian divergence are reassessed in terms of these arguments.
Embryonic lethality is not sufficient to explain hourglass-like conservation of vertebrate embryos
- BiologyEvoDevo
- 2018
The results suggest that negative selection by embryonic lethality could not explain hourglass-like conservation of animal embryos, and highlights the potential contribution of alternative mechanisms such as the diversifying effect of positive selections against earlier and later stages, and developmental constraints which lead to conservation of mid-embryonic stages.

Comparative Transcriptomics Reveals Distinct Patterns of Gene Expression Conservation through Vertebrate Embryogenesis
- BiologybioRxiv
- 2020
A phylogenetic comparative approach is used to characterize expression conservation pattern of each gene at each evolutionary node across vertebrates and finds an enrichment of genes exhibiting early conservation, hourglass, late conservation patterns and a large depletion of gene exhibiting no distinguishable pattern of conservation in both microarray and RNA-seq data sets.

- BiologyProceedings of the Royal Society of London. Series B: Biological Sciences

It is hypothesize that numerous tightly delimited developmental modules exist during the mid–embryonic period and the high level of timing changes between these modules may be an important evolutionary mechanism giving rise to the diversity of vertebrates.

The molecular results suggest, albeit weakly, that a phylotypic stage (or period) indeed exists and its temporal location, sometimes between the first-somites stage and the formation of the posterior neuropore, was in approximate agreement with the morphologically defined phylotypesic stage.

It is argued that temporal colinearity only occurs in cells with high mitotic rates, which results in a strong linkage between patterning and growth control and makes the patterning process unidirectional, from anterior, proximal and early, to posterior, distal and late, a model referred to as the 'Einbahnstrasse'.
