Early development in the extant Ginkgo biloba is characterized by a series of distinct ontogenetic stages.
Content validity is the extent to which a measure comprehensively covers domains of interest [ 54] and was assured by the development of the measure having incorporated the extant literature, and the perspectives of people with mental illness and professional experts.
Middle Presumed evolution of the neural tube, eye vesicle, eye-cup, and lens, based on the embryological development of the nervous system of extant vertebrates.
In this analysis I suggest hypothetical reconstructions of germband stages of fossil taxa, based on what we know of the development of extant species (see Methods).
I have used current knowledge on the development of extant arthropods, together with published descriptions of fossils, to reconstruct the germband stages of a series of key taxa leading from the arthropod lower stem group to crown group taxa.
To this end, I use the understanding gleaned from the analysis of development of extant taxa to suggest possible processes involved in the development of fossil taxa.
In parallel with ontologies and OBO, the MIBBI project fosters coordinated development of extant minimum information checklists needed to fully understand the context, methods, data and conclusions that pertain to an experiment (6).
The methodology exemplifies a model for refining and re-theorising a linguistic framework to be robustly applied in linguistic analysis of a particular field in a particular context, starting with the collection and analysis of a small sample using extant theory, then development of the refined model based on a larger study.
Germination and seedling development in the fossil are nearly identical to that of the extant gymnosperm G. biloba.
Therefore, assessment, documentation, analysis and conservation of the extant genetic diversity are essential prerequisites to mine useful genes for the development of the new, adaptive cultivars (Chang 1984).
