Willi Hennig (1913-1976): His Life, Legacy and the Future of Phylogenetic
Systematics
A joint event with the Linnean Society of London, Natural History
Museum and the Systematics Association.
Wednesday 27th November 2013
Willi Hennig (1913-1976) arguably exerted the strongest theoretical influence
on the practice and course of systematic biology of anyone since Charles Darwin.
A dipterist by speciality, Hennig did not simply study flies but considered a
whole host of issues pertinent to biological classification, writing on the
science of taxonomy and systematics, revising and promoting discussion on topics
such as the precise meaning of relationship, the nature of systematic evidence
and how these matters impinge on a general understanding of monophyly, homology
and our knowledge of the processes of evolution. It would not seem unreasonable
to suggest that nearly all comparative biology has been altered because of
his contribution. For the most part, those contributions had a major impact
in the English-speaking world through his 1966 book Phylogenetic
Systematics (reprinted in 1979 and again in 1999), which, oddly enough, at
the time of its original publication, was not greeted with enthusiasm by most
reviewers, who "generally failed to perceive the possibilities in applying
Hennig's approach" (Rosen et al. 1979, in the Forward to the first
republishing of Phylogenetic Systematics). Phylogenetic Systematics, or
cladistics as it is more widely known, slowly but steadily, began to permeate
almost every sphere of systematic biology, from prokaryotes to mammals, from
those exploring the emerging areas of molecular biology, to those still
attempting to gain the evolutionary significance of wing venation in insects.
The Linnean Society has been especially
significant in the early dissemination of Hennig's ideas, sponsoring perhaps the
first symposium exploring cladistics with respect to a group of organisms
(Interrelationships of Fishes, Academic Press, 1973), assisting and
encouraging the first reprinting of Phylogenetic Systematics and
awarding Hennig their Gold medal (Biological Journal of the Linnean
Society 6: 375).
In 2013, if Hennig had lived, he would have been 100 years old. This day
meeting has been put together with the aim of celebrating that anniversary and
has been organised to explore details of the man, his ideas and how they have
affected systematic biology Ц and perhaps of greatest significance, how his
ideas and influence will continue to do so. It is also timely that the first in
depth biography of Hennig, From Taxonomy to Phylogenetics. Life and Work of
Willi Hennig (Brill 2013), has been published this year and its author,
Michael Schmitt, will be present to give an overview. This will take place as an
evening lecture (18.00 - 19.00 which is open to all.
Speakers:
Wili Xylander, Charissa Varma, David Williams, Ole Seberg, Pascal Tassy,
Leandro C. S. Assis, Marcelo Carvalho, Malte Ebach, Andy Brower, Gareth Nelson,
Quentin Wheeler and Michael Schmitt
