{Scientists for the first time have created animals with dinosaur features using fossils as a guide. They have transformed chicken beaks into something similar to a dinosaur snout.}<\/p>\n
Many have pondered the idea of recreating dinosaurs while novelists and sci-fi film directors tempted our imagination with such as creations the Jurassic park film and novel series.<\/p>\n
A research team led by Yale paleontologist and developmental biologist Bhart-Anjan S. Bhullar and Harvard developmental biologist Arhat Abzhanov, have conducted a successful experiment which allowed them to create chickens with dinosaur-like features. <\/p>\n
Researchers were able to transform chicken embryos in a laboratory into specimens with a snout and palate configuration similar to that of small dinosaurs such as Velociraptor and Archaeopteryx, according to a Yale press-release published on Tuesday.<\/p>\n
\u201cOur goal here was to understand the molecular underpinnings of an important evolutionary transition, not to create a \u2018dino-chicken\u2019 simply for the sake of it,\u201d said Bhullar, lead author of the study.<\/p>\n
\u201cThe beak is a crucial part of the avian feeding apparatus, and is the component of the avian skeleton that has perhaps diversified most extensively and most radically \u2013 consider flamingos, parrots, hawks, pelicans, and hummingbirds, among others,\u201d Bhullar said.<\/p>\n
\u201cYet little work has been done on what exactly a beak is, anatomically, and how it got that way either evolutionarily or developmentally.\u201d<\/p>\n
The research team also found that major living lineages of birds have a unique, median gene expression zone of two different facial development genes early in embryonic development, which the non-beaked creatures lack. When they blocked this gene expression not only did the beak structure revert into a snout, but the process also caused the palatine bone on the roof of the mouth to go back to a dinosaur-like state.<\/p>\n
\u201cThis was unexpected and demonstrates the way in which a single, simple developmental mechanism can have wide-ranging and unexpected effects,\u201d Bhullar said..<\/p>\n
