That's right. The theory was first put forward and researched by Alexander Graham Bell - modern estimates put the heritability of longevity between 20 and 50 percent.

The fruit fly selective breeding experiments began in the 80's and within 10 generations the average lifespan on the test groups increased by 30%. In human terms, that would place the current average of 78 to just over 100.

The studies continued and at 50 generations, the lifespan had doubled. Not only were the flies longer lived, they were more hardy as well. They required less food and water and were much more resistant to extremes in habitat.

Of course, they were also fat, lethargic and lazy and completely stopped reproducing naturally.
