temperature , prey size and salinity . To take into account other environmental ...

A more reliable way of inferring regions of origin might be to compare the
distribution of the more " primitive " members of a group with that of more “
derived ” forms . ( This requires that we know how to tell primitive from derived
forms , a ...
