Is there any science behind unicorns/ pegasis?

Pegasus, considering the fact that unicorns were, and still are, real. 

Yes, there is. This is because in advanced cases of DNA grafting, you would be able to graft wings onto a horse. This does not, however, account for the fact that the horse would not be able to use or take care of the wings that they were given.  

How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?   answer :   the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.
