Morgan was eventually awarded the Nobel Prize in Physiology or Medicine for demonstrating that chromosomes act as the carriers of inheritance in 1936.

Of the lion’s share of laboratory research, Morgan’s fruit flies became one of the most popular study models of evolution. After surviving through an unknown number of laboratory experiments, however, fruit flies are still fruit flies. “We are due for a renaissance,” said Alejandro Sánchez Alvarado, a biologist at the Stowers Institute for Medical Research in Kansas City, Missouri in an interview with Quanta Magazine science writer Emily Singer. “We have narrowed our focus to a handful of organisms that statistically are highly unlikely to encompass the gamut of biological activity on the planet.” The evolution industry is on a mission to find a new study model of evolution.
