Toward Defining the Course of Evolution: Minimum Change for a Specific Tree Topology
TL;DR: A method is presented that is asserted to provide all hypothetical ancestral character states that are consistent with describing the descent of the present-day character states in a minimum number of changes of state using a predetermined phylogenetic relationship among the taxa represented.
Journal ArticleDOI
Distinguishing Homologous From Analogous Proteins
TL;DR: This work provides a means by which it is possible to determine whether two groups of related proteins have a common ancestor or are of independent origin, and how many nucleotide positions must differ in the genes encoding the two presumptively homologous proteins.
Journal ArticleDOI
Tempo and mode in evolution.
TL;DR: In the introduction to his book, Simpson averred that an essential part of his study was an "attempted synthesis of paleontology and genetics," an effort that pervaded the whole book, but was particularly the subject of the first two chapters, which accounted for nearly half the book's pages.
Journal ArticleDOI
Homology: a personal view on some of the problems
TL;DR: This work examines 15 terminological problems related to the usage of homology and its associated terms and suggests a set of definitions that are intended to be totally consistent among themselves and also as consistent as possible with most current usage.
