I think you misunderstood my post somewhat Aelia [img]smile.gif[/img] . Let´s see. Depression is a disease, like alzheimers etc. It´s a of interferance of neural transmittors, GABA or glutamic acid. That´s why alcohol actually does help against depression (no funny ideas now johnny

). So a mutation in a receptor for these substances, or in the substance itself, would of course be hereditary. Transcription of genes in the womb is more often caused by protein gradients that off cell-cell contact. A higher concentration of a certain protein will lead to a higher transcription of a certain gene. Just another correction, most organs are NOT developed at birth, nervous system, skeleteton etc. That the environment should determine gene transcription has not been proved (unless you of course eat something toxious). External stimuli cause changes in synaptic activity, but there are many more responses than gene transcription (this is a very slow step). To explain my thinking in your speach example. If a person has the capability to speek perfectly, his/her physiology is perfect! It´s the external stimuli, environment that is, that´s lacking. Maybe physiology was a bad word to use
