- >>>>How can you pick up a mannerism genetically?
-
- It appears to me that there's different specific questions
- implied :
-
- 1) What specific behavioral tendencies can be passed on through
- purely hereditary mechanisms, and how might they be related
- to specific mannerisms ?
-
- For example, is it possible to have a genetic pattern
- that results in a neurochemical pattern during development
- that causes certain neuromuscular responses to be more likely
- than others ? A subtle structural imbalance in a muscle group
- for example, making a facial tic more likely than otherwise.
-
- This also related to the dog breeding example. Dogs don't,
- as far as I know, inherit chracteristics learned by their
- sires, they both pick up elements from the same 'gene pool.'
-
- 2) Can a mannerism LEARNED in one's lifetime be inherited by offspring
- through a purely genetic mechanism ?
-
- In other words, do we really want to ressurect Lamarckian
- theory in some form ? There was some talk of this in
- popular literature a while back, but I don't know if anything
- ever came of it ? Some weird experiments with molds
- learning from being poisoned, and supposedly passing on that
- learning to subsequent generations of mold. I don't recall
- it being very persuasive, though.
-
- So far, the consensus seems to be that learned things are
- not inherited (though determining exactly what is learned
- and what is genetically influenced tendency is often very
- tricky).
-
- kind regards,
