Interesting case about the lepidopteras. When the animal is put to new
environement to recover the extinct spiece it starts to adapt . This progress
will change its phenotype (characterics) to fill the requirements of that environement.
In old times there were a saber thooth tigers which look alike modern tigers. Those animals
have the same egolocical position, to hunt in the forrest. 
Same thing works also in humans. If you look how the education to some 
work changes the humans actions and outlook.   :o)
