Fathers Spend More Time With Children Who Resemble Them, Study Suggests

In an article dated July 8, 2009, ScienceDaily reported on parenting that is biased by a resemblance between father and child.

The investment of a father in the care and education of a child is a decisive factor for the child's development, growth and even survival, particularly in countries with high infant mortality. As this behavior is transmitted from generation to generation, it can evolve by natural selection. Evolutionary theory predicts that men should have developed the capacity to recognise their biological children. This recognition of paternity can be made on the basis of physical resemblance.
