A new study has opened a door to discover how birds have evolved to create colorful plumage.
Unrest is responsible for some of the most remarkable performances in the animal government, and a new study of plants from nearly 100 modern bird species helps to find out how this color variation evolved.
The irisensitive phenomena are when an object of color changes when it is viewed in different ways.
A team of University of Bristol investigated electron microscope to find extracts of # to study the birds of 97 species of most advanced birds, from the Zoological Museum in Copenhagen.
Researchers found fundamentals found to have found the most distinct melanoma forms of all kinds of birds, including one that has head or neck broken, or both, in contrast to black, gray and brown feathers, the permanent melanomas contain.
A form of melanosome in demand with the thickness of the protein surface of keratin defines the color that's produced.
The new study is the first time melanoma vaccination in iris men has been analyzed in a large scale, previously used to provide the colors in fossilized animals.
Dr. Jakob Vinther, co-author of study and a prominent researcher in the field of paleocolour at Bristol School of Biological Sciences, said the research scientists can see on fossils of prehistoric birds and see how have their melanomas changed over the centuries.
He adds: "This shows how we have the tool now to map the evolution of iris in fossil lines.
"It opens the door to discover many new discoveries of smileys in fossil birds and other dinosaurs."
The researchers took Scaniacypselus, a relation of modern power battles, and Primotrogon, precursor of modern trogones, to see if their 48 million-year-old parents also have iridescent plumage.
The model claimed that Primotrogon was probably likely, but it was strongly in place of head melanosomes, in contrast to his modern descendant.
Leading writer Klara Norden, the study conducted under her undergraduate study in Bristol & # 39; s School of Earth Sciences, said: "It is already known that structural color is responsible for 70% of color reproduction in birds.
"These two facts can be linked – birds develop various forms of melanoma to reach any larger variety in color.
"I want to invent if we can improve today's predictive fossil-based models based on melanosome morphology, by finding all kinds of melanomas in free springs."
