A person’s next of kin (NOK) is that person’s closest living blood relative or relatives. Some countries, such as the United States, have a legal definition of “next of kin”. … If a person dies intestate with no identifiable next of kin, the person’s estate generally escheats (i.e., legally reverts) to the government.

Two other studies in Evolution & Human Behavior, one in 2000 and one in 2007, found that newborns actually look more like their mothers than their fathers in the first three days of their lives, as judged by unrelated assessors. … That, too, has a possible evolutionary explanation, according to D.

Do fathers and sons have the same DNA?

Each son receives DNA for his Y chromosome from his father. This DNA is not mixed with that of the mother, and it is identical to that of the father, unless a mutation occurs. It has been estimated that a mutation occurs about once every 500 generations, or every 15,000 years, give or take a few millennia.
