Case 5: Common Case Study

Posing a question where students can answer openly, it is observed that these reflect deductively to reason why species evolve:

 

For a long time it was the custom to cut off the ears of dogs, do you think that if this practice was repeated for generations, finally get their offspring born with short ears?

 

 

Some responses elementary students:

- No, because although her parents are the been cropped, this does not inherit his son because he is not in their genes.

- Yes, that would evolve and dog-eared.

 

In this case we selected a common breed of urban dog which he intervenes when is small to clip the ears. There are many theories explaining why they performed this act with some breeds of dogs, but focusing on the question posed above, one might say that the theory that such is not a genetic trait of these dog breeds arises for much that he cut off the ears of these animals and many years go, continue to have the ears of the same size.
