The article linked to the picture below is great observable science that shows how chickens can have a wide variety of color in their feathers. The article states, "Birds show an amazing diversity in plumage colour and patterning. But what are the genetic mechanisms creating such patterns? In a new study published today in PLOS Genetics, Swedish and French researchers report that two independent mutations are required to explain the development of the sex-linked barring pattern in chicken. Both mutations affect the function of CDKN2A, a tumour suppressor gene associated with melanoma in humans". The article continues by stating, "Research in pigmentation biology has made major advances the last 20 years in identifying genes controlling variation in pigmentation in mammals and birds".
The article then states, "Our data show that sex-linked barring is caused by two independent mutations that act together. One is a regulatory mutation that increases the expression of CDKN2A. The other changes the protein sequence and makes the protein less functionally active".
The researcher then uses this as an example of evolution when he states, "this represents an evolutionary process in which the regulatory mutation occurred first followed by the mutation affecting the protein structure". But what does he mean by evolution? If he means that changes in existing genetic information can result in different traits such a new color patterns then I would agree. But this fact is then often distorted to get people to believe that this same process could be used to change apes into man, dinosaurs into birds, or amoebas into men. This is absolutely false! This study, along with every single study, only shows the changing of existing genetic information. In no case has new genetic information been created, much less new functioning genetic information.
