Evolutionary systematics

In the early 1950s Mayr became disillusioned with the SSE and Evolution. The relative dominance of geneticists in the society frustrated his attempts to secure a balance with the concerns of evolutionary systematics. Moreover, while editor of Evolution (1946 to 1949), Mayr largely failed (despite considerable effort) to recruit papers from systematists representing an evolutionary perspective. This situation did not change under the next editor, Edwin Colbert. As Mayr turned away from Evolution, he turned toward Systematic Zoology. Mayr joined the editorial board in 1953 just as his co-authored textbook on systematic principles appeared (Mayr et ah, 1953). ...

Despite many years of investigation directed toward these and other related questions (Baker, 1990 Carlson, 1991 Boucot and Wilson, 1994 Copper and Gourvennec, 1996 Williams et al, 1996 Alvarez and Carlson, 1998), the answers remain elusive. This is due, in part, to the fact that the phylogenetic methods available to us do not ideally suit the full range of palaeontological data available in the form of both morphological variation and relative stratigraphic (temporal) position. Traditional methods of evolutionary systematics (sensu Simpson, 1961) often have relied heavily on... 

The first is a network that has minimum area but a maximum number of exchangers as proposed by the algorithmic—evolutionary approach (10). The algorithmic part of this method is the development of a minimum area network. The evolutionary part employs a set of rules to modify systematically the initial network. The three rules presented ate heuristic in nature and seek to combine exchangers and stream spHts to reduce network cost. The problem of reducing stream spHts appears difficult to researchers. 

The genus Fuchsia consists of perhaps 100 species, enjoys a wide distribntion, and offers a variety of systematic and evolutionary challenges. In addition to attracting purely botanical interest. Fuchsia is also of considerable horticnltnral value. Our interest in the genns concerns sect. Skinnera which consists of three New Zealand species, F. excorticata L. f., F. perscandens Cockayne Allan, and F. procumbens R. Cnnn., and the Tahitian endemic F. cyrtandroides Moore. A fourth taxon, F. x colensoi Hook. f. occurs wherever the ranges of F. excorticata and F. perscandens overlap.
