TLDR
It is argued that, 185 years after von Baer's law was first formulated, its main concepts after proper refurbishing remain surprisingly relevant in revealing the fundamentals of the evolution-development connection, and suggest that their explanation should become the focus of renewed research.About:

TL;DR: It is found that the breadth of gene expression and the extent of purifying selection gradually decrease during development, whereas the amount of positive selection and expression of new genes increase during development.

The macroevolutionary consequences of phenotypic integration: from development to deep time.
TL;DR: The authors showed that phenotypic integration can produce both more and less disparate organisms than would be expected under random walk models by repartitioning variance in preferred directions, which can also be expected to favour homoplasy and convergent evolution.

TL;DR: It is proposed that a phylum may be defined as a collection of species whose gene expression at the mid-developmental transition is both highly conserved among them, yet divergent relative to other species.
The macroevolutionary consequences of phenotypic integration: from development to deep time
TL;DR: It is demonstrated that phenotypic integration can produce both more and less disparate organisms than would be expected under random walk models by repartitioning variance in preferred directions, and that this effect can also be expected to favour homoplasy and convergent evolution.

Journal ArticleDOI
A series of normal stages in the development of the chick embryo
TL;DR: The preparation of a series of normal stages of the chick embryo does not need justification at a time when chick ernbryos are not only widely used in descriptive and experimental embryology but are proving to be increasingly valuable in medical research, as in work on viruses and cancer.
Journal ArticleDOI
A series of normal stages in the development of the chick embryo
TL;DR: In this article, a series of normal stages of the chick embryo is described in terms of the length of time of incubation, except for the first three days during which more detailed characteristics such as the number of somites are applied.
Journal ArticleDOI
The global diversity of birds in space and time
TL;DR: It is found that birds have undergone a strong increase in diversification rate from about 50 million years ago to the near present, with a number of significant rate increases, both within songbirds and within other young and mostly temperate radiations including the waterfowl, gulls and woodpeckers.

Evo-Devo and an Expanding Evolutionary Synthesis: A Genetic Theory of Morphological Evolution
TL;DR: Eight principles derived from molecular and evolutionary developmental biology are outlined and recent studies of species divergence that have led to a genetic theory of morphological evolution are reviewed.

A major developmental transition in early xenopus embryos: I. characterization and timing of cellular changes at the midblastula stage
TL;DR: The Xenopus embryo undergoes 12 rapid synchronous cleavages followed by a period of slower asynchronous divisions more typical of somatic cells, termed the midblastula transition (MBT), which shows that at the MBT the blastomeres become motile and transcriptionally active for the first time.
