Remarkable vid of a mouse embryo developing

This series of videos from McDole et al. shows the development of a mouse embryo, captured using adaptive light-sheet microscopy, and highlights cell division (part A), cell movements (part B) and tissue dynamics (parts C, D) during embryogenesis. Paper. McDole, K., Guignard, L., Amat, F., Berger, A., Malandain, G., Royer, L.A., Turaga, S.C., Branson, K., […]

Mechanics as well as genetics is needed for viable embryo development

From Suzan Mazur at Oscillations, With the ramping up of investigations in various parts of the world into the mechanics of biology, I’ve decided to post my conversation with Institut Curie biophysicist Emmanuel Farge on the role of mechanics in reprogramming the embryo [2010], relating to his work first published in the scientific literature in 2003, […]

Biophysics is starting to matter in evolution

From Suzan Mazur at Oscillations: The mechanics of morphogenesis is something European scientists, in particular, seem to find intriguing. However, physical biology is an approach many classical biologists in America have had a difficult time in the past understanding as well as accepting, as evidenced by vociferous attacks in the blogosphere on scientists working in […]

The “developmental hourglass” doesn’t actually need to be true

It’s too cool a concept for accuracy to matter. Further to “Remember the ‘developmental hourglass’? Well, not so fast,” Jonathan Wells writes to point out that vertebrate embryos more closely resemble each on another than do their adult forms only if one carefully cherry-picks the desired stages, which are long after the beginning of development. In […]

Darwinism Embryology Evolution Intelligent Design

Remember the “developmental hourglass”? Well, not so fast.

“The hourglass model of embryonic evolution predicts an hourglass-like divergence during animal embryogenesis – with embryos being more divergent at the earliest and latest stages but conserved during a mid-embryonic (phylotypic) period that serves as a source of the basic body plan for animals within a phylum.” Well, not so fast: From Hajk-Georg Drost, Philipp […]

Stuff Doesn’t Evolve–It Just Shows Up in the Beginning

Here’s a news article from Phys.Org on a lamprey study. Actually it’s a study concerning phylogenetics and using gene regulatory mechanisms to figure out the relationships that exist. It turns out that in the lamprey, which is part of the Cambrian explosion, the same kind of hind brain gene regulatory mechanisms are in place as […]
