Previous Sexual Partners Can Influence Another Male's Offspring

Telegony (microchimerism) is not studied by pseudoscientists because it refutes the theory of evolution

"A new study by the University of Seattle and the Fred Hutchinson Cancer Research Center has revealed that Women absorb and retain living DNA of every single man they have sex with. When scientists were trying to determine if women who had been pregnant with a son might be more predisposed to diseases usually found in men, then also found in the study that the female brain also absorbs male DNA."

"Le Dantec wrote that some farmer told him that once his swine copulated with a boar and their pigs absolutely resembled the father in color. But when the same swine copulated with another boar some pigs of the second farrow still resembled the color of the male pig the swine had copulated first."

"Scientists believe the phenomenon occurs because molecules from the first partner’s seminal fluid absorbs into the female’s immature eggs, and manifests in them once they’ve matured. In other words, previous partners’ semen may actually affect female eggs, regardless of whether they’re fertilized or not.

“Our discovery complicates our entire view of how variation is transmitted across generations, but also opens up exciting new possibilities and avenues of research. Just as we think we have things figured out, nature throws us a curve ball and shows us how much we still have to learn,” said lead researcher Dr. Angela Crean."

"Certainly until recently it would have been thought impossible because the DNA genome of the sperm was thought to be the only thing passed down to future generations by the male.

“However, there is now evidence that so-called ‘epigenetic’ changes, can be passed down at least one or two generations, and such changes can be influenced by diet and other lifestyle differences."

"And size might not matter as much as previously thought. Seminal fluid is chemically complex, with proteins and tic messengers called RNA floating in the liquid outside of the sperm.

So even the effects of a small ejaculate could be significant, giving females a largely unexplored bonus from sex.

Prof Bonduriansky said: 'It is pretty clear now seminal fluid is packed with paternal RNA. And this would be in humans, mice, fruit flies and nematode worms at least.'

He added: 'In some systems, mostly nematodes and mice, there is evidence these RNAs can play a role in early embryonic development.' "

My comment: Telegony is an inconvenient subject for evolutionary biologists. That's why it's been studied only by few scientists. But some serious researchers have already revealed the complex mechanisms that prove these scientific facts. For example:

http://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1004296

Traits of an organisms are not determined by DNA of the semen. Cellular programming and differentiation is directed by non coding RNA molecules such as microRNAs and lncRNAs. These molecules are rich in seminal fluid and they absorb and attach into woman's tissues and cells. They might affect epigenetic programming of embryonic cells making their own imprinting on the cells. This is why a white couple might have a black baby. DNA sequences don't determine the skin color. Human traits are determined by epigenetic information layers.

Interesting is, that the Bible teaches us about this phenomenon:

Matthew 19:5 "And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh."
