ABRACADABRA..........wave of the wand , "hey presto .............."

I asked my son what the babies ( Kept it simple by using the word babies ) of the following animals will be elephant , monkey , horse , whale , human , finch , shark , dog , cat etc . And guess what ? He laughed and said ..."Elephants produce elephants , monkeys produce monkeys , horses produce horses , finches produce finches , cats produce cats , dogs produce dogs ."
(Ok , we do know that there is variation within the created kinds but there are horizontal boundaries within living organisms that can not be passed .)
So , why is it Darwin took from his imaginary world , where a bear can turn into a whale and applied it to the real world by claiming a bear can really turn into a whale given enough time ?
Charles Darwin :
" In North America the black bear was seen by Hearne swimming for hours with widely open mouth, thus catching, like a whale, insects in the water. Even in so extreme a case as this, if the supply of insects were constant, and if better adapted competitors did not already exist in the country, I can see no difficulty in a race of bears being rendered, by natural selection, more and more aquatic in their structure and habits, with larger and larger mouths, till a creature was produced as monstrous as a whale." (On the Origin of Species (1859), original edition, p. 184)
Charles Darwin :
"I still maintain that there is no special difficulty in a bear's mouth being enlarged to any degree useful to its changing habits." ("More Letters of Charles Darwin," 1903, page 162) 
This quote by Darwin himself is based on pure imagination and wishful thinking . When Darwin wrote , he was not aware of ....... genetic homeostasis .....because if he was he would have known this is impossible . The entire external and internal structure of the bear would have to be re - modeled in order to get from land dwelling to water dwelling . To do this would take more than blind random chance and accident .
I find this amusing how an adult loses the abilty to differentiate between fiction and reality , but a child recognizes it immediately .
