However, the discovery of highly conserved developmental control genes among metazoans, new fossil finds, and revolutionary new hypotheses about metazoan relationships have breathed new life into speculation about the original body plan
of bilaterians and the pelago-benthic life cycle (Knoll and Carroll, 1999; Irwin and Davidson, 2002).

England had been expected to be in seeding pool two for the finals in Japan and South Korea, but a report in yesterday's Daily Telegraph revealed senior officials of football's governing body plan
to include them among the world's eight elite sides in pool one for the draw on December 1.
Major changes in body plan

By letting them grow past the point at which they would be planted in the womb, experts in Britain and America say for the first time they can define how embryos will take shape and how the body plan
Documents submitted to the US authorities have disclosed that the governing body plan

France, GRENOBLE ALPES METROPOLE announced tender for Contract notice for Territorial information system: constitution of a metropolitan street streamlined body plan
Humans and most animals develop their body plan
during embryo development and they can not change it after; for example, we can not grow an extra arm.
Weiss said that a general principle of developmental biology is that evolution favours reliability and robust switches ensure that our genetic programs give rise to a consistent body plan
to ensure that babies have one heart, two arms, ten fingers, and so forth.
The finding came as a surprise to researchers since it has been thought that the arrangement of genes on chromosomes helps determine how an organism's body plan
will be laid out.
Studies in evolutionary development biology have shown that most evolution at the population and species levels consists of small-scale alterations in developmental pathways within a single body plan
(also called "tinkering") rather than evolution of entirely new body plans
The transition from radial to bilateral symmetry can be viewed as one of the most important events in body plan
evolution, and the study of the extant cnidarians and ctenophores may therefore help us to understand the evolution of the anterior-posterior and dorso-ventral axes of bilaterians.
Kirschner's laboratory investigates three broad, diverse areas: regulation of the cell cycle, the role of cytoskeleton in cell morphogenesis, and mechanisms of establishing the basic vertebrate body plan
