This document is clearly an official document of an english newspaper that is written by scientific people and also this newspaper is updated every day so that is a proof that is official.

The author of this website is wikipedia, this scientific newspaper was buyed by wikipedia in 2011 and as we think they bought this newspaper because it was very productive and also this website only speaks about one important theme that is Science. 

As we can see this text is addressed to an audience of a broad knowledge in the field of science. Specifically it addresses to an age of eleventh grade more or less. This is shown  in the way that the author get expressed and also the vocabulary that in this case he is using.

This text is written in english so we observe that the author could be for another country but, he could want that all the people understand his observation about DNA and also what he thinks. 

In our opinion we think that this website is for giving to the public a great knowledge about DNA and  specially in animals. And also this could help many people to make an investigation about this, as in our case are doing. 

This page shows some features of unreliability because it  comes from Wikipedia, however, as I said before this page can be only uploaded by  files that are well appreciated by the audience.
