The standard textbook treatment of how a single fertilised egg becomes a complex organism, integrating genetics, cell biology and evolution into one developmental framework.

Surveys regeneration across many animal groups and argues it should be studied as a distinct developmental process with its own rules, not simply as embryonic development run a second time.

Shows mathematically that two interacting chemicals diffusing at different rates can spontaneously generate stable spatial patterns, proposing a mechanism for how a uniform embryo breaks symmetry.

Shows that a nucleus taken from a fully differentiated adult intestinal cell can direct the development of a complete, fertile frog, proving differentiation does not permanently alter the genome.

Establishes a small, transparent, rapidly breeding roundworm as a genetic model organism whose complete cell lineage could eventually be mapped, arguing simplicity, not scale, is what makes an organism tractable.

Identifies the bithorax gene complex and shows its genes sit on the chromosome in the same order as the body segments they control, the first evidence for what became the Hox code.

A systematic mutagenesis screen identifies the genes that lay down the fruit fly's segmented body plan, founding the genetic approach to pattern formation.

Argues a single genotype's capacity to produce different phenotypes in different environments can itself drive evolutionary diversification, ahead of genetic change rather than following it.

Revisits the century-old organizer experiment through modern molecular biology, showing embryos regulate their own patterning through a self-correcting network of secreted signals.

Shows a single adult intestinal stem cell can self-organise into a functioning crypt-villus structure in a dish, founding the organoid model for studying organ formation.
