Living Fossils: Introduction to the Casebook,ow just how evolution actually works. But our “observations” are problematical; ranging from DNA sequences, distributions of alleles in populations, and on up through the origins and extinctions of major taxa, the “data” of evolutionary biology are of vastly different scale, quality, and, some would

Evolutionary Stasis in the Elephant-Shrew, , ,his group of 150 outrageously endowed species—informally known as .—was apparently confined to the obscure South Sea islands of Hi-yi-yi. I say “was” in the acknowledgment that, quite tragically (and conveniently?), snouters, islands, and Stümpke were erased in a nuclear test accident two decades ag

,The Tree-Shrew, , A “Living Model” of the Ancestral Primate?,es (indeed, the tree-shrew fossil record is exceptionally poor), over the past several decades these mammals have regularly been held up as a “l(fā)iving model” of the “ancestral primate.” The tree-shrews have thus been regarded widely as approximating (usually in some unspecified way or ways) the ances

What is a Tarsier?,a primate that is somehow intermediate between the lower lemurs and lorises and the higher anthropoids. There have been two major recent views of the broader relationships of . (and, by association, fossil taxa) within Primates: (1) following Pocock (1918), extant tarsiiforms and Anthropoidea are co

Are There Any Anthropoid Primate Living Fossils?,, the implication is of a living taxon that differs only slightly if at all in known morphology from an early fossil member of its clade, at whatever taxonomic rank. In this spirit, we will examine the “higher” or anthropoid primates to determine if any taxa, including some previously suggested, qua

Evolutionary Pattern and Process in the Sister-Group Alcelaphini-Aepycerotini (Mammalia: Bovidae),eresting aspects of evolution concerns the very different histories in terms of morphological diversification that such sistertaxa often have. Elsewhere I have suggested that the causes of different kinds of evolution may be especially well studied in low-ranking sister-groups that include a fossil
