The ideas that were developed by Gutmann and his colleagues were innovative and pathbreaking for morphology and evolutionary biology.
We suggest that the fields of evo-devo, functional morphology, and evolutionary ecology should be united under a common framework based on three predictions.
In addition to the argument from comparative morphology and evolutionary relationship, outlined in the previous paragraph and also discussed by Malcomber et al. (2006), genetic studies show that overexpression of floral genes affects the sterile lemmas but not the true glumes (Komatsu et al. 2003; Prasad et al. 2001).
Here we use an integrative approach that combines multiple levels of organization (gene networks, development, and phenotype) as well as multiple fields (population genetics, paleoecology and ecology, morphology, and evolutionary developmental biology) to gain a more complete understanding of population differentiation in the wild.
Their results indicate that the historic difficulties in classifying these ferns have been due to a combination of evolutionary stasis, with disparate groups appearing to be closely related due to shared ancestral morphologies, and evolutionary convergence, with the repeated evolution of similar features.
This article discusses the algae in terms of their morphology, ecology, and evolutionary features.
Complementing the molecular estimates for the human chimpanzee divergence dates, the last 20 years have heralded major breakthroughs in our understanding of early hominin morphology, behavior, and evolutionary relationships.
Tunicates are so interesting and unique biological models not only because of their particular developmental plan, distinctive morphology, and key evolutionary location but also due to their genome plasticity, evolutionary rates, and patterns.
The field of plant evolutionary development (evo-devo) integrates molecular genetics, phylogenetics, comparative morphology, and modern evolutionary theory to understand developmental and genetic changes underlying variation in plant form and function.
The description of species is fundamental to the science of zoology, including taxonomy, phylogenetic systematics, functional morphology and ultimately evolutionary biology and ecology.
Specifically, we characterize broad patterns of morphometric variation using multivariate analysis, evaluate the extent and phylogenetic distribution of cave-associated morphologies, and discuss evolutionary, developmental, and taxonomic implications.
