Understanding the head is one of the great challenges in the fields of comparative anatomy,
developmental biology, and palaeontology of arthropods. Numerous conflicting views and …

The three major taxa with metameric segmentation (annelids, arthropods, and chordates)
appear to use three very different molecular strategies to generate segments. However …

During development cells and tissues undergo changes in pattern and form that employ a
wider range of physical mechanisms than at any other time in an organism's life. This book …

The construction of a stable phylogeny for the Cestoda, indicating the interrelationships of
recognised orders and other major lineages, has proceeded iteratively since the group first …

Study of the model organisms of developmental biology was crucial in establishing evo–
devo as a new discipline. However, it has been claimed that this limited sample of …

Functional factors such as optimal design and adaptive value have been the central concern
of evolutionary biology since the advent of the New Synthesis. By contrast, evolutionary …

Ontogenetic stages of trilobites have traditionally been recognized on the basis of the
development of exoskeletal segmentation. The established protaspid, meraspid, and …

Studying development in diverse taxa can address a central issue in evolutionary biology:
how morphological diversity arises through the evolution of developmental mechanisms …

Evolutionary developmental biology and niche‐construction theory have much in common,
despite independent intellectual origins. Both place emphasis on the role of ontogenetic …

Different sources of data on the evolution of segmentation lead to very different conclusions.
Molecular similarities in the developmental pathways generating a segmented body plan …
