He speculated why genes would carry a memory from one generation to the next. What evolutionary purpose could it serve?
Maybe imprinting was used as a means of some sort of trans-generational adaption.
He thought it could be used for a mother to send messages to her baby in the next generation.
Something that always puzzled me ever since I was a medical student was what stops the baby's head jamming up in the birth canal.
The baby of course is growing in one generation, but the mother's pelvis was growing in the previous generation. So if the mother was starving when she was growing, so she had a small pelvis. Maybe her eggs had captured that information and so they were instructing the growth genes of the future babies to not work so much and for the baby not to grow too much so as to jam up in the birth canal. So, so there was some sort of coordination between the growths in two generations. That struck me as entirely reasonable.
He published his ideas in an obscure journal and largely forgot about it. After all, there was no evidence for any of this. It was pure speculation. Then four years later Marcus received an E-mail from a doctor in Sweden.
Really came as a bolt out of the blue I just got an E-mail in May 2000 saying my paper was the only thing he could find in the literature, that in anyway, er, sort of tied in with his basic observations.
