Repeated Evolutionary Changes of Leaf Morphology Caused by Mutations to a Homeobox Gene
Elucidating the genetic basis of morphological changes in evolution remains a major challenge in biology. Repeated independent trait changes are of particular interest because they can indicate adaptation in different lineages or genetic and developmental constraints on generating morphological variation. In animals, changes to "hot spot" genes with minimal pleiotropy and large phenotypic effec...
متن کاملEvolution of Reproductive Morphology in Leaf Endophytes
The endophytic lifestyle has played an important role in the evolution of the morphology of reproductive structures (body) in one of the most problematic groups in fungal classification, the Leotiomycetes (Ascomycota). Mapping fungal morphologies to two groups in the Leiotiomycetes, the Rhytismatales and Hemiphacidiaceae reveals significant divergence in body size, shape and complexity. Mapping...
متن کاملEvolutionary consequences of many-to-one mapping of jaw morphology to mechanics in labrid fishes.
Many physiological traits consist of two hierarchically related levels: physical structures and the emergent functional properties of those structures. Because selection tends to act on the emergent functional traits, the evolution of structural phenotypes will depend on the nature of the form-function relationship. Complex physiological or biomechanical traits are often characterized by many-t...
متن کاملOne-Level Prosodic Morphology
Recent developments in theoretical linguistics have lead to a widespread acceptance of constraint-based analyses of prosodic morphology phenomena such as truncation, infixation, floating morphemes and reduplication. Of these, reduplication is particularly challenging for state-of-the-art computational morphology, since it involves copying of some part of a phonological string. In this paper I a...
متن کاملEvolutionary Morphology for Polycube Robots
Recent developments in robot technology have led to modular robots that are assembled from multiple parts. Modular robots have pros and cons. Their shape can be changed to suit a particular purpose and the same parts can be reused, which makes them fault-tolerant and extendable. However, such freedom and flexibility lead to higher cost so as to decide the configuration and actions to meet the p...
