A theory on how science and spiritualism could be working together.
Perhaps having memories of a former life are transferred in memory locked into DNA transferred when reproducing. This is an area that may not have been investigated thoroughly yet. Is it possible that a new child carries this DNA and it is usually absorbed or 'watered down' by interaction with the mates DNA. Could certain attributes of maturity and common sense be also a part of this generational transfer. Is it possible that troubled societies have a higher percentage of very young mothers and fathers causing a loss of accumulated wisdom. This would also lead to the belief that older and wiser parents (particularly male due to physiological reasons) would pass on more stable and intelligent offspring that possesses more natural talent and instinct.
Would this mean that a person that does not have offspring disappears from the planet altogether? A perfect way to discard genes that are not quite up to the task of evolution? It certainly makes a lot os sense.
The main question therefore is:
Does what we do on a day to day basis including memories, attitudes, self realisation slowly enter itself onto our DNA thereby getting 'smarter' as we grow older. And is that 'intelligence' transferred to the offspring of the mating couple. Does this mean that older fathers make smarter babies? I'm sure the oldest members of a large family would totally disagree with this theory but of course the result of these trends would not always happen within one generation. Is that why it is human instinct to send off all the young men to be killed in battle to ensure a higher percentage of older fathers are able to restore balance between brain and brawn? Physically a younger father may produce the superior DNA package, but life experience, maturity, instinctive knowledge and behaviour all come with age and are the essential ingredients in producing intelligent offspring.
