Population geneticists and phylogeneticists view tree structures diflerently'To the
phylogeneticist, tree structures are the objects of study and the branching patterns a tree …

Exploration of the relationship between gene trees and their containing species trees leads
to consideration of how to reconstruct species trees from gene trees and of the concept of …

▪ Abstract Polymorphism, or variation within species, is common in all kinds of data and is
the major focus of research on microevolution. However, polymorphism is often ignored by …

This chapter reviews an approach to the study of speciation that is based on patterns of
genetic variation within and between closely related species. Historically, research on the …

Evolutionary trees can be constructed from the haplotypes observed with molecular surveys
of sequence or restriction site variation. Such gene trees can be constructed regardless of …

The remarkably rapid growth of molecular genetics during the past two decades and
concomitant advances in DNA technology have had an enormous impact in systematic and …

Systematists and evolutionary geneticists don't often talk to each other, and they routinely
dispaiage each other's work as being of little relevance to evolution. Systematists sometimes …

Despite persistent debate on the nature of species, the widespread adoption of Mayr's
biological species concept has led to a heavy emphasis on the importance of reproductive …

The origins and development of the study of speciation, hybrid zones and phylogeography
are outlined using evolutionary iconography. This traces the ideas in this field from Lamarck …
