Who does not know that? Right after the baby has come into the world the affectionate speculations about similarities between the newborn child and the parents start. Dad‘s nose is clearly recognizable, isn‘t it? And these big blue eyes are definitely like mum‘s, aren’t they? Well, when visiting the newborn child or looking at the received birth announcement card one statement is pretty common: Just like Daddy! But is that right? Do strong similarities between a newborn child and its daddy really exist? Is that a tactic from Mother Nature to deepen the relationship between father and baby right after the birth? It would be a logical comprehensible approach. The mother can be sure about her baby, because she gives birth to it, but concerning the father doubts can remain. Strong similarities between the father and the newborn child could reduce present doubts. Interestingly, the approach could not be proven empirically. A variety of studies from Britain and North America have analyzed that matter and ended up in very surprising results. First of all, a strong similarity between the newborn child and the mother could be proven scientifically, but a strong similarity between the baby and the father was not found. In addition, the studies came to the result, that the new mothers see a strong similarity between her children and their father. What was Mother Nature thinking when she invented that?
