Termites may have evolved sterile castes through hormone signaling changes in their cockroach ancestors. Eusocial insects, like ants, bees, and termites, have rigid caste systems: some individuals reproduce, while others are temporarily sterile workers or permanently sterile soldiers. This division of labor allows colonies to thrive, but the question remains:  how did these species evolve…

The Genetics Society of America Medal is awarded to an individual for outstanding contributions to the field of genetics in the last 15 years. Recipients of the GSA Medal are recognized for elegant and highly-meaningful contributions to modern genetics, exemplifying the ingenuity of GSA membership. The 2017 recipient is David M. Kingsley, whose work in…

In the 1940s, C. H. Waddington discovered a peculiar phenomenon in fruit flies: traits could appear in response to environmental stress in an individual’s lifetime and then be passed down to future generations. Waddington proposed that this wasn’t the inheritance of acquired traits, but actually due to pre-existing genetic variation that had no effect until…

We are pleased to announce that David Kingsley, PhD is the 2017 recipient of the GSA Medal for outstanding contributions to the field of genetics in the past 15 years. His experimental work has shifted paradigms about how the physical traits of vertebrate organisms evolve. Kingsley is a Professor and Howard Hughes Medical Institute Investigator…

Today’s guest author is Emma Farley, a postdoctoral researcher in Mike Levine’s lab, which recently relocated to Princeton (formerly at University of California, Berkeley). Sea squirts (Ciona intestanalis) are a classic system for the study of development. They were a favorite of early developmental biologists like Laurent Chabry, Ed Conklin, and Thomas Hunt Morgan. Over…
