fruit flies (Drosophila)

 
Clayton M. Christensen, Innovator's dilemma, 1997, 2000                [ ]

p.3
When I began my search for an answer to the puzzle of why the best firms can fail, a friend offered some sage advice.  "Those who study genetics avoid studying humans," he noted.  "Because new generations come along only every thirty years or so, it takes a long time to understand the cause and effect of any changes. Instead, they study fruit flies, because they are conceived, born, mature, and die all within a single day. If you want to understand why something happens in business, study the disk drive industry. Those companies are the closest things to fruit flies that the business world will ever see."

  According to Creighton, Morgan later confessed that he had known about Stern's work a the time.  But, as he explained (about a year after his intervention), he was also aware of the fact that, even though Creighton and McClintock had begun the summer before, it would have been a simple matter for Stern to overtake them.  With Drosophila [fruit flies], one need not wait for entire growing season to learn the results of genetic crosses; one can get a new generation every ten days.  Creighton recalls Morgan's saying, “I thought it was about time that corn got a chance to beat Drosophila!”
