FREMUNG Tonight there-are millions of liny biological alarm clocks buried in (he mud of the Mississippi Hivcr, .Most of them are set for a certain hour of a Special day in July 1962. On lhat day millions of alarms will go off and (be clock bearers will rise to (lie surface of the wajer, shed their skins twice, mate, lay their eggs and be dead before 'they see their second sun- fise. Why arc we interested in may- flics if we don't plan (o control them? ' Tbis is an example, of research which is not directly applicable; in other.words it is pure research, Yet Ihis work may provide a small piece of a fascinating biological biological puzzle, We know (hat birds navigate on stars and that spawn- Ing salmon can smell Iheir way upstream (o Iheir birth place.
