Thyroxine's evolutionary roots

Article Abstract:

The evolutionary origin of thyroxine was reviewed with focus on its iodine dependency and its function as a thyroid hormone. The origin of thyroid glands in ancestors of vertebrates is explained by a suggestion that iodine incorporated into organic molecules are released in the digestive tact where they can be absorbed into the body to ensure a supply of iodine. Another suggestion considers thyroxine as an indicator of developmental readiness in larvae based from the finding that thyroxine alone is adequate to continue adult rudiment development in sea urchin larvae.

Pierre Teilhard de Chardin: being, critical thresholds, and evolutionary thought

Article Abstract:

The work of Jesuit scientist and speculative naturalist Pierre Chardin de Teilhard was reviewed. Teilhard's work provided a new reorganizational framework to scientists and philosophers. His books, namely, 'The Divine Milieu,' 'The Phenomenon of Man,' and 'The Future of Man' showcased his attempt to unite secular science with the evolutionary philosophy of his time. Teilhard will be best remembered for demonstrating the dialectic and convergent nature of time and for facilitating covergences between science and philosophy and the disciplines attached to each.

The new biology of obsessive-compulsive disorder: implications for evolutionary psychology

Article Abstract:

A study was conducted to examine biological and anthropological literature related to obsessive-compulsive disorder (OCD) to suggest how the disease may be associated with concerns in the social and behavioral sciences. Several studies investigated neurological diseases associated with OCD and characterized the relationship between OCD and the basal ganglia. However, the characterization did not determine whether the ganglia circuitry dysfunction played a significant role in controlling normal life behaviors that were related to boundaries, order and rules.
