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.
Brady realised that the liberties of the Charter were limited and argued that the liberties were the grant of the King. By putting Magna Carta in historical context, he cast doubt on its contemporary political relevance; his historical understanding did not survive the Glorious Revolution, which, according to the historian J. G. A. Pocock, marked a setback for the course of English historiography.
