The recent experiment carried through by researchers at Harvard and Yale has proven bird beaks have dinosaur origins. Scientists, however, deny bird beaks can be turned into dinosaur snouts as many more proofs are requested to support this hypothesis.
Researchers at the Harvard and Yale Universities decided to swim against the tide setting forward a different hypothesis related to the origin of the species.
Unlike most scientists, who try to identify the different stages that species have gone through until they have finally reached the present form, scientists at Yale and Harvard have turned nowadays birds into dinosaurs.
During the experiment, researches have applied various matters to chicken and bird beaks in order to change their molecular form.
The proteins in the embryonic chicken cells have undergone multiple gradual modifications until they have turned into a snout-shaped form. This new beak is, according to their recent statements, the dinosaur snout that birds might have had before they became what we know them to be today.
At the end of the experiment, molecular experts have all agreed that birds stem from dinosaurs.
The reason why their beaks are now so different from the original dinosaur snouts is the fact that beaks are crucial for birds’ feeding apparatus. Since chickens use it to procure food, the beak has suffered various transformations in order to keep up with the environmental changes.
Nevertheless, the beak is definitely a trace of dinosaur origins, as scientists have not only managed to revert the formation process during their experiment, but they also created a new palatine bone. The new mouth shape represents, in fact the ancestral shape of the birds’ beaks.
Experts, on the other hand, have raised many questions in relation to the relevancy of the recent findings. In their opinion, the recent experiment is biased as the data was not accurately documented.
Moreover, molecular experts claim scientists have to perform many other similar experiments in order to find a real connection between birds’ beaks and dinosaur snouts.
The recent experiment was labeled as superfluous by many researchers, who have dedicated great part of their lives to the study of the ancestral origins. They claim the study of the gene and molecular transformation cannot account for the entire comprehensive process that beaks have gone through until they have reached their current forms.
Ralph S. Marcucio, a developmental biologist at the University of California, San Francisco, explained that the data becomes confusing when carefully analyzed.
“It’s a simple kind of thing, but when you look at the actual pieces of data, it tends to fall apart,” he concluded.
