RECOMBINGATION? OF COURSE NOT. BUT THAT WOULD A TRULY DARWINIAN SYSTEM...

INCIDENTALLY CANCER DOES EVOLVE IN US BUT IT IS A ONE-GENERATION WONDER, BEING ONLY PASSED ON IN ONLY A COUPLE OF SPECIES OF THE DOG FAMILY (where it has become a sexually transmitted disease). IN OURSELVES IT EVOLVES GENETICALLY IN ONE LIFETIME AND WE KNOW THE UNITS THAT ARE SELECTED FOR. PROBLEM IS THAT THERE ARE AN ALMOST INFINITE VARIETY OF CANCERS AND AS WE LEARN TO TREAT ONE, OTHERS COME TO THE FORE.

The evidence for early onset of psychopathic and related symptoms is fairly convincing. See:
Frick, P. J., & White, S. F. (2008). Research Review: The importance of callous-unemotional traits for developmental models of aggressive and antisocial behavior. Journal of Child Psychology and Psychiatry, 49(4), 359-375. doi:10.1111/j.1469-7610.2007.01862.x
The current paper reviews research suggesting that the presence of a callous and unemotional interpersonal style designates an important subgroup of antisocial and aggressive youth. Specifically, callous-unemotional (CU) traits (e.g., lack of guilt, absence of empathy, callous use of others) seem to be relatively stable across childhood and adolescence and they designate a group of youth with a particularly severe, aggressive, and stable pattern of antisocial behavior. Further, antisocial youth with CU traits show a number of distinct emotional, cognitive, and personality characteristics compared to other antisocial youth. These characteristics of youth with CU traits have important implications for causal models of antisocial and aggressive behavior, for methods used to study antisocial youth, and for assessing and treating antisocial and aggressive behavior in children and adolescents.

NONSENSE—THE AUTHORS ARE NOT EVEN TALKING ABOUT PSYCHOPATHIC BEHAVIOR BUT RATHER ‘AGGRESSIVE AND ANTISOCIAL BEHAVIOR’

I don’t know of any real data that can be used to estimate how selection falls on psychopaths and their relatives, only anecdotes. Anecdotally, psychopaths make lousy mates and parents, suggesting that relatives do indeed suffer from having a psychopathic relative. In simple societies individuals who seem like psychopaths are often exiled or assassinated often with the assent of their families. If psychopathy is in a frequency dependent equilibrium, selection on family members that might share genes (or culture) for psychopathy would be part of the selection against it.

TRUMP IS NOT THE PERFECT MATE BUT IS HE REALLY A ‘LOUSY FATHER’?—ASK HIS CHILDREN, IVANKA, DONALD JR ETC—THEY SURE DON’T ACT LIKE THEY HATE HIM. HOW ABOUT VICTIMS OF HINDU AND MUSLIM HONOR KILLINGS WHO ARE ‘ASSASSINATED’ ‘WITH THE ASSENT OF THEIR FAMILIES’—ARE THE VICTIMS PSYCHOPATHS OR ARE THEIR KILLERS? FOR THE EVOLUTIONARY GENETICS OF HONOR KILLINGS—SEE BELOW. NOTE THAT CULTURAL PEOPLE HAVE OFFERED LITTLE OR NOTHING OF VALUE ON THIS SUBJECT BUT EVOLUTINARY GENETICS AT ONCE SUGGESTS AN INTERESTING AND VERY STRONG EFFECT.
