Understanding development is relevant to understanding evolution because developmental processes structure the expression of phenotypic variation upon which natural selection acts. Advances in developmental biology are fueling a new synthesis of developmental and evolutionary biology, but it remains unclear how to use developmental information that largely derives from a few model organisms to ...

Current research in developmental biology aims to link developmental genetic pathways with the processes going on at cellular and tissue level. Normal processes will only take place under specific sequential conditions at the level of the pathways. Disrupting or altering pathways may mean disrupted or altered development. This paper is part of a larger work exploring methods of detecting and ex...

dna methylation as epigenetic mark plays a key role in normal differential and developmental processes as well as in dynamic gene regulation at the genomic level. to assess dna methylation pattern in different developmental stages of aeluropus littoralis, methylation sensitive amplified polymorphism (msap) was used. methylation and demethylation status at the ccgg recognition site were tracked ...

We report the results of tests investigating the recognition of faces, places, and objects in a developmental agnosic, because dissociations of visual recognition in developmental agnosics provide insight into the separable procedures performing recognition and the developmental origins of these procedures. TA is a software engineer in his early 40s with developmental prosopagnosia. He performs...
