Of course, that poor term has been used and abused, describing everything from totally innate behaviors, like nest-building, to totally learned behavior, like actions at a tennis net (she has great net instincts). So I don't know what sense Anders is using the term in. <br><br></div><div class="gmail_default" style="font-family:comic sans ms,sans-serif;font-size:small;color:rgb(0,0,0)">I don't know that dogs have lost anything by being domesticated. I'd like to see some data. There are wild dog packs all over the earth, so if anyone has studied them surely there are some data on what if anything they have lost. <br><br></div><div class="gmail_default" style="font-family:comic sans ms,sans-serif;font-size:small;color:rgb(0,0,0)">From learning studies I've read, there is no such thing as extinction - reducing a learned behavior to zero. That would mean that subjects' attempts to relearn the behavior take just as long as it did to learn it in the first place. It takes brain damage to totally unlearn a behavior. Otherwise it is just suppressed and can be relearned, perhaps very readily.<br><br></div><div class="gmail_default" style="font-family:comic sans ms,sans-serif;font-size:small;color:rgb(0,0,0)">I have no idea how long it takes for evolution to get rid of an unlearned instinct.<br><br></div><div class="gmail_default" style="font-family:comic sans ms,sans-serif;font-size:small;color:rgb(0,0,0)">bill w<br></div><br></div>
