Strength in numbers: High phenotypic variance in early Cambrian trilobites and its evolutionary implications.

BioEssays : news and reviews in molecular, cellular and developmental biology - 1 Nov 2007

Hughes Nigel C

Abstract excerpt

Analysis of the degree of intraspecific morphological polymorphism during the evolutionary history of trilobites using an informatic approach(1) provides striking evidence of a long-suspected but previously unsubstantiated pattern: degrees of polymorphism are markedly higher in phylogenetically b...
