Crozier Journal: Myrmecological News Volume: 15 Pages: 1-5 URL: www.myrmecologicalnews.org Keywords: Formicidae, Myrmecia pilosula, cytogenetics, population genetics, taxonomy, chromosome evolution, review. Abstract: Three myrmecologists (R.H. Crozier, R.W. Taylor and H.T. Imai) with different academic backgrounds and interests met in Australia in 1975. They later established an air-drying technique for ant chromosome observations and surveyed hundreds of Australian ant species centred around the Jack jumper Myrmecia pilosula, and proposed the so-called "Minimum Interaction Theory" (a new theory for chromosome evolution). This is an account of their work together. Publisher: The Austrian Society of Entomofaunistics ISSN: Print: 1994-4136 - Online: 1997-3500
