neo-lamarckism
[ noun ]
a modern Lamarckian theory emphasizing the importance of environmental factors in genetic changes and retaining the notion of the inheritance of acquired characters
<noun.cognition>




Neo-Lamarckism \Ne`o-La*marck"ism\, n. (Biol.)
Lamarckism as revived, modified, and expounded by recent
biologists, esp. as maintaining that the offspring inherits
characters acquired by the parent from change of environment,
use or disuse of parts, etc.; -- opposed of {Neo-Darwinism}
(which see, above).

Note: This theory has been thoroughly discredited, though it
had some support for a time in the Soviet Union due to
the influence of the biologist Lysenko.--
