Dinosaur beaks to bird brains

Posted: 02 Dec 2013 01:21 PM PST

Why beaks evolved in some theropod dinosaurs and what their function might have been is the subject of new research by an international team of palaeontologists.

Excerpt: This new study reveals that keratinous beaks played an important role in stabilizing the skeletal structure during feeding, making the skull less susceptible to bending and deformation.

Edentulism, beaks, and biomechanical innovations in the evolution of theropod dinosaurs

Excerpt: However,several skeletal traits and adaptations, gradually acquired within distinct clades of Maniraptoriformes, appear to have been induced by or sparked dietary diversification (4).

Synopsis of the article:

Birds supposedly evolved from dinosaurs but not all extant bird species fly. However, all of them eat. Dinosaur beaks and bird beaks enable them to eat.

Like all other vertebrates, birds produce pheromones that control their reproduction. That fact suggests natural selection in dinosaurs and birds is for food and sexual selection is for pheromones. That fact is also supported by overwhelming experimental evidence. It refutes anything associated with mutation-driven evolution in dinosaurs to birds, or in microbes to man.

About James V. Kohl 1308 Articles
James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
