Developmental dysfluency is considered a normal part of childhood development. About twenty five percent of children experience some loss in fluency. Symptoms Symptoms of developmental dysfluency include the repetition of sounds or pauses between words. These symptoms have generally been noted within youngsters from 18 months to 5 years of age. This may persist for weeks or months but eventually disappears due to the maturation of the child s nervous system. ex. Daddy, I was, I was, um, um, I was... Instances like the aforementioned example, indicate, according to Richard Trubo, that the child is learning to use language. On the other hand, children with stutter stuttering disorder , will likely repeat sounds or one syllable words three or more times. They may also prolong sounds for two or more seconds. In comparison, stuttering can be seen as a process where a word appears to become stuck, and the person may grimace, jerk the head or neck as he struggles to overcome the stutter. Children with normal dysfluency tend to have stuttering difficulties that come and go. Generally this is during preschool years and the problem normally ceases altogether by the time a child starts school.

Unreferenced date December 2009 Comparative biology is a multidisciplinary approach to understanding organismic diversity biodiversity that uses natural variation and disparity to elucidate phylogenetic history. Comparative biologists attempt to understand the diversity and complexity of life at all levels from genes, to anatomy, to behavior and the critical role of organisms in ecosystems. Integrating these specific research areas is the objective of comparative biology, a field that not only promises to give us a broader, more meaningful understanding of life on Earth, but also provides a foundation for our effort to secure a sustainable environmental future. An improved knowledge of life in all its complexity is key to dealing with the especially urgent challenges of today that come with the loss of species due to the destruction or disruption of natural habitats via human mediated processes such as global warming . Comparative biology encompasses Evolutionary Biology , Systematics , Neontology , Paleontology , Ethology , Anthropology , and Biogeography as well as historical approaches to Developmentalbiology , Genomics , Physiology , Ecology and many other areas of the biological sciences. Whereas much of biology tends to focus on a single exemplar organism or a small subset of model organisms, comparative biology is a cross lineage approach to understanding the phylogenetic history and interactions among individuals or higher taxa . The comparative approach also has numerous applications in human health, genetics , biomedicine , and conservation biology .
