After all of the progressive attacks upon family, now they want to tell us that family is important, because family evolved.
They wrote that monogamy arose to protect the children from infanticide. It seems that if an animal is not monogamous the next suitor will kill off the children so the mother will mate with the male.
But, now that they have almost destroyed family, they find research to support it.
What a mind scramble.
What do you think?
