Gila trout, native only to headwater streams that vein over the Mogollon Rim of New Mexico and Arizona, have expressed in their genetic makeup a mapping of how to survive in the vestiges of what surely was a large and contiguous range.
The Magna Carta was a significant influence on the long  historical process that has resulted in the rule of constitutional  law today.    The Magna Carta came about because King John (who only became king  in 1199 when his brother King Richard I died) had a reputation for  being tyrannical. His reign was marred by continuous war losses,  beginning with the loss of Normandy to Philippe Auguste of France  and ending with England torn by civil war.
Once signed by the king, the Magna Carta became a list of promises that he was supposed to keep. They included promises to protect the freedom and rights of the Church, to consult more closely with the barons (especially on matters such as taxes) and to guarantee certain freedoms to all free men.ven though this was not really true-the Magna Carta was a solution to a specific situation rather than a grand declaration of rights for all people-it came to be used as a kind of bill of rights.
