Pangenesis
Just for fun. My science instructor add a "Stupid Science" topic each week. This week's was about pangenesis. This is the text:
n According to pangenesis, a trait acquired by a parent during his or her lifetime could be passed on to children ("soft" inheritance). If a man worked to develop large muscles, for instance, the repeated habit of weight-lifting would somehow leave a lasting record in the cells of his body. Particles carrying this information were called "gemmules." They would migrate from all parts of the body to the sex cells, whereby they could be inherited by the offspring. We wish…<O
</O
<O></O>
Again, this is just for fun. Has anyone ever heard about this? If so, is there any validity?

Animal behaviouralists are fairly certain that not only the will to migrate but also the path of migration of migratory birds is genetically encoded into their brains. Check out

That map can only be developed thorugh learning about the world around them over the ages. I other words, this is knowledge, and an associated behaviour, passed on genetically.

the whole thing is conflicting, like the experiment where they cut off the tails of 20 generations of rats, yet each generation still grew a tail. are poeple born with a light farmer tan now days????
i really think that we (science) think that we know more about this genetic stuff than what we really know. plus, the brain is still one of the biggest mysteries out there.

I've heard of the idea of soft inheritance but it seems a little bit wacky. If I used my right middle finger to give the "Jersey Salute" fifty times a day, that finger would get larger and my children would be born with large middle fingers. Fortunately, all of my kids have normal fingers. If someone breaks their left arm five times a year is their kid going to be born with one arm that just breaks itself? From what I know about genetics, the whole idea doesn't make any sense. I should know, I'm a geneticist.
Okay, I made that last sentence up.

Cute...
The article on migratory patterns was an interesting thought, though. Perhaps some repitition in the parents can influence the instincts in the offspring.

i am thinking it is more a patriachial type thing than genetic inheritence.
that is shown among elephants and other animals, the paths to water, food sources, migratory, etc.. are passed on from generation to generation not by genetics but by knowledge and experince.
this came to light during the 70's? 80's? after a civil war in what i think was zaire, but can not remember, maybe it was uganda even. anyway, whole elephant herds were killed off and the learned knowledge of where to go was broken for future generations. they had to basically use what few elephants were left to reintroduce the new elephants from other places the areas to go and help re-establish the generations of knowledge that was lost.
it is still an ongoing process even now with i guess good results.

Soft inheritance is a interesting concept,although I see it as being hard to prove as being 100% credible. We know that genetics will pass on physical features in humans such as oversized ears, hawk beaks and other facial features....
I cannot see a consistently trained stimuli of a human parent, being passed on to their offspring as constantly provable. If a particular stimuli was, I feel it would be more of a result of a learned act from their home environment, rather than inherited... jmo
On a fleeting thought here though, we may have in my state a classic example of detached soft inheritance. It could be known as the," double wide mobile home effect".
