Developmental and genomic insight into the origin of the tardigrade body plan

Evolution &Development, Volume 26, Issue 4, July 2024.
Three hypotheses for the homology of tardigrade segments to segments of other panarthropods. H, tardigrade head; T1‐T4, tardigrade trunk segment 1–trunk segment 4. Abstract Tardigrada is an ancient lineage of miniaturized animals. As an outgroup of the well‐studied Arthropoda and Onychophora, studies of tardigrades hold the potential to reveal ...

The dorsal lip of the blastopore

, 2019
In an early gastrula, mesoderm (red) involution occurs at the dorsal lip of the blastopore. Most mesoderm will involute here. Over time, involution spreads around the blastopore lip as the lip gets smaller and smaller due to epiboly by the ectoderm (blue)

Movie 4

, 2015
Shows vegetal cleavage and the large amount of contraction that occurs in the vegetal endoderm leading up to blastopore formation. Contraction begins at about 3.3 hours elapsed time (frame 20).

Emerging trends in the study of spiralian larvae

Evolution &Development, Volume 26, Issue 4, July 2024.
The evolution and diversification of ciliated spiralian larvae. Abstract Many animals undergo indirect development, where their embryogenesis produces an intermediate life stage, or larva, that is often free‐living and later metamorphoses into an adult.

Model schematic.

, 2014
(A) Diagrams of blastopore closure from the lateral side. The ectoderm and neurectoderm (gray) spreads over the embryo during gastrulation. Involution begins on the dorsal side at t = 0, and begins on the ventral side at tP; the blastopore closes at tC ...
