Question: How long had Darrell Royal been working as a head coach the year he learned about the wishbone offense? Passage:In 1968, Texas head coach Darrell Royal and his offensive coordinator Emory Bellard introduced what would become known as the wishbone offense. The wishbone was derived from the Split-T offense run at Oklahoma under Bud Wilkinson. In the formation, the quarterback lines up with a fullback and two tailbacks behind him, and on any play may keep the ball, hand off to the fullback, or pitch to a tailback. From the time Bryant arrived at Alabama through the 1970 season, the Crimson Tide ran a pro-style offense. By 1969, Bryant began to recruit larger linemen and tailbacks, and after a pair of six win seasons in 1969 and 1970, Bryant saw the success of the wishbone for the Longhorns and decided to implement the offense for the 1971 season. In spring 1971, Alabama assistants Mal Moore and Jimmy Sharpe traveled to Austin where they saw first hand how the wishbone operated during Texas' final week of spring practice.

question:
Question: Did other scientists keep blending inheritance open for further consideration? Passage:In the preface, Fisher considers some general points, including that there must be an understanding of natural selection distinct from that of evolution, and that the then-recent advances in the field of genetics (see history of genetics) now allowed this. In the first chapter, Fisher considers the nature of inheritance, rejecting blending inheritance, because it would eliminate genetic variance, in favour of particulate inheritance. The second chapter introduces Fisher's fundamental theorem of natural selection. The third considers the evolution of dominance, which Fisher believed was strongly influenced by modifiers. Other chapters discuss parental investment, Fisher's geometric model, concerning how spontaneous mutations affect biological fitness, Fisher's principle which explains why the sex ratio between males and females is almost always 1:1, reproductive value, examining the demography of having girl children. Using his knowledge of statistics, the Fisherian runaway, which explores how sexual selection can lead to a positive feedback runaway loop, producing features such as the peacock's plumage.
