An inroad into an understanding of the complex molecular interactions on which
development is based can be achieved by uncovering the minimum requirements that …

Most schemes for embryonic pattern formation are built around the notion of lateral
inhibition. Models of this type arise in many settings, and all share some common …

Publisher Summary This chapter focuses on the problem of pattern specification in early
insect embryogenesis, essentially on the formal level characteristic of “classical” …

We discuss theoretical and experimental approaches to three distinct developmental
systems that illustrate how theory can influence experimental work and vice-versa. The …

It is a widely held view that axis formation is based essentially on pre-localized
determinants. However, the robustness of early development, the pattern regulation …

We present a classification of developmental mechanisms that have been shown
experimentally to generate pattern and form in metazoan organisms. We propose that all …

Modeling of pattern formation in hydra has revealed basic mechanisms that underlie the
reproducible generation of complex and self-regulating patterns. Organizing regions can be …

One of the main aims of developmental biology is to understand how a single and
apparently homogeneous egg cell achieves the intricate complexity of the adult. Here we …

Driesch's statement, made around 1900, that the physics and chemistry of his day were
unable to explain self-regulation during embryogenesis was correct and could be extended …

Publisher Summary The basic embryological phenomena do recur at insect metamorphosis.
This chapter describes how work with insects has produced some central information …
