Third, there are limits on the ways in which speciation can occur in general and even narrower limits in the case of any particular monophyletic group of

Heterochrony refers to an alteration in time, or a change in order, of one or more events. Although macroevolutionary events play a defining role in speciation, microevolutionary events, acting over extended periods of time (especially with strong selection),

Abstract. Phylogenetic heterochrony can be perceived in how distantly related Speciation via floral heterochrony and presumed mycorrhizal host switching of endemic Butterfly-orchids on the Azorean archipelago June 2014 American Journal of Botany 101(6) Abstract. Heterochrony is known as a developmental change in the timing or rate of ontogenetic events across phylogenetic lineages. It is a key concept synthesizing development into ecology and evolution to explore the mechanisms of how developmental processes impact on phenotypic novelties. Li and Johnston 2000 (cited under Heterochrony in Plants: General Overviews) is a review of the literature through the 20th century on heterochrony in plants. Two works, Raff 1996 and Hall 1998 , present a general overview of evolutionary developmental biology, placing heterochrony within that broader context. Lethaia, 9: 245-259.

168-176. Hoboken, N.J.: Wiley-Liss 10.1002/jez.b.21083 Differences in diet and possibly in feeding mode are believed to have caused these phenotypic changes. Phenotypic plasticity is described in terms of a qualitative model of heterochrony in which phenotypic change in morphology is explained as retardation of the normal developmental rate.

2003-05-01 · Heterochrony has been identified as the most common mode of speciation in virtually all lineages (Gould, 1977, McNamara, 1995, McNabb and Wilson, 1997, Yeh, 2002), although how these changes are implemented is still unclear. Cichlid fishes in African rift lakes have undergone rapid speciation, resulting in “species flocks” with more than 300 endemic species in some of the lakes. Most researchers assume that there is little phenotypic variation in cichlid fishes. I report here extensive phenotypic plasticity in a Neotropical cichlid species. I examined the influence of diet on trophic morphology during ontogeny ossification heterochrony in the therian postcranial skeleton and the marsupial-placental dichotomy Postcranial ossification sequences in 24 therian mammals and three outgroup taxa were obtained using clear staining and computed tomography to test the hypothesis that the marsupial forelimb is developmentally accelerated, and to assess Start studying chapter 24 speciation.
