By looking at which genes are activated in the brains of queens and workers of different ant species, Dr. [Daniel] Kronauer and his colleagues determined that a hormone called insulin-peptide 2, or ILP2, played the most important role.

"'It is mind-blowing' that cells from such evolutionarily distant species can share these developmental instructions, says Ali Brivanlou, a stem cell biologist at The Rockefeller University in New York City and a senior author on the new study. The organizer 'has been conserved evolutionarily over hundreds of millions of years, so not seeing it would have been a surprise,' he says. But, 'There is something really emotional about looking that far back at human origin.'"
