That was what a friend said talking about modifying human germinal lines. A week later, discussing about transhumanism another friend told me that "Science will solve all problems". This two sentences were said some months ago but I still have them fixed and would like to write about them.

In this case (modifying human germinal lines) we have the possibility to gain the piece of knowledge to cure some big deseases (cancers, senescence, autoinmmune diseases...) but at the cost of losing the common biological definition of o...
