Brain Vs. Brawn In Carpenter Ants: A Chromatin Epigenetic Tale

Genome sequences of seven well-studied ant species give researchers a detailed look at molecular mechanisms - including what may be a basis for complex behavioral differences in two worker castes in the Florida carpenter ant, Camponotus floridanus - basically, epigenetics. Epigenetics is the study of how the expression or suppression of particular genes by chemical modifications affects an organism's physical characteristics, development, and behavior; if that sounds vague or perhaps even...
