neo-Lamarckism Modern evolutionary theories that in some sense allow the possibility that acquired characteristics may be inherited (as proposed by Lamarck). For example, in 1980 E. J. Steele proposed that what in effect is Lamarckian evolution may occur by the insertion of new genetic material into the host genome by a retrovirus.
