ANNOUNCEMENT - INTERNATIONAL MEETING

Interrelationships of the Platyhelminthes

14-16 July 1999
The Linnean Society of London
Burlington House, Piccadilly
London W1V OLQ

The phylum Platyhelminthes comprises the numerous and diverse flatworms.
They hold a fascination for biologists at a multitude of levels and perhaps
occupy a pivotal position in the evolution of the Metazoa.  Are they the
earliest divergent bilaterians still extant? Do they hold the key to the
evolution of the Metazoa? Do they exhibit a body plan from which more
complex coelomate organisms can be derived? With such fundamental questions
relying on our understanding of the group, it is unfortunate that the
phylogeny of the group is so poorly understood and that the very monophyly
of the group is not established.

The group is successful not only in terms of numbers of species (one
estimate is over 100,000 spp.) but also in the diversity of ecological
niches they occupy and life-history strategies they pursue. Terrestrial,
limnetic and marine free-living flatworms ('turbellarians') are abundant
and ubiquitous but perhaps not so familiar as the Neodermata, comprised of
obligate parasites such as cestodes, digeneans and monogeneans.

The division between workers on free-living flatworms and parasitologists
has been considerable, if not complete, and has impeded a wider
understanding of the phylum from a systematic and a general comparative
approach.  In an attempt to address this problem a meeting will be held at
the Linnean Society in London when it is hoped that this division will be
bridged and a unified approach be developed for the study of the phylogeny
of the platyhelminths. Experts and specialists in up to 30 different groups
of organisms and disciplines will review the progress made in flatworm
phylogenetics since the seminal work of Ulrich Ehlers Das Phylogenetische
System der Plathelminthes (1985).  The advances in sperm morphology,
confocal microscopy, neuroanatomy, comparative morphology, molecular
systematics, parasitology, and modern phylogenetics are brought to bear on
providing a unified system that tracks the evolutionary origins and
radiation of the group.

The meeting will appeal to those working directly with flatworms (e.g.
parasitologists, and developmental biologists) as well as those interested
in general zoology, (morphological and molecular) systematics,
phylogenetics and evolutionary biology.
