Document Summary
Ancestor is of keyboards today are the same as the type writer before. This was created to minimize mechanical jamming: sometimes the bars that made the imprint on the page go to fast and jams them. Dvorak: faster keyboard, no jamming (electric, is fast. If we changed from qwerty to dvorak it would require a lot of work: its very inconvenient, we are very ef cient (or t) at the qwerty keyboard. Would go through the intermediate (not t) Would then be more t as you got used to dvorak (more t: this is called inertia. Normal distribution: usually the mean is the highest tness, range around the mean that is viable. Any individual that is out of the range is not selected and removed from the allele pool. Selective ns: if a pop has to go through a intervening period were there is lower tness (not rewarded) to get to a higher tness it will never happen.
