Mormons don't practice polygamy anymore due to social pressure. Social pressure works that's why it's used
They were hunted down and killed. That partly helped. Hunted down and massacred by the US military, the US Government.
The United States derives its view of marital monogamy as morally superior to polygamy from its (the United States)
Christian heritage.
There have been many societies that allowed men to have multiple wives (even Jesus was questioned in the New Testament about ancient Jews having multiple wives).
The science of biology does not object to it neither does the social science of sociology. The science of biology does not even care about marriage as that is a mere cultural and religious thing. Biology per the Theory of Evolution focuses on on what it terms
"fitness." Which is something different than what Republicans, Libertarians, and Democrats think. That term and concept is not about "strength" or "making money."
"Fitness" as in "survival of the fittest" has two ways it is used as a concept in biology:
1) To denote an organism that produces more offspring relative to another organism of the same species.
2) The prevalence of certain genes in a population.
So, "survival of the fittest" has to do with
rationally explaining why certain genetic traits are more prevalent in population relative to other genetic traits found in a population. Or it is used to help rational explanation why certain genetic traits disappear from a population.
What is important to note in this is that a non-married man impregnating over 100 women
is an amoral issue in the science of biology. From the stand point of biology he has proven more
fit than me (who has produced no offspring, consequently I do not contribute
my genes to the greater population). He proves more "fit" than me even if he is a "Dead Beat Dad," and even if I adopt 100 children and provide for them all.
So, in terms of lesbian marriages, if being such is merely and only genetically determined (epigeneyics has replaced "genetic determinism" the prefix "epi" means "beyond," "above," or "more than"), then if all lesbians in America married and did not get impregnated by male sperm,
we would expect then that the genetic trait of lesbians would eventually perish from the genetic pool found in the United States of America.
But
genetic determinism is no longer held as a reasonable explanation for all traits found in individuals. Roughly around the year 2010 the science of biology underwent the beginning of a new revolution in which "epigenetics" is now the rallying flag.
Epigenetics and the influence of our genes | Courtney Griffins | TEDxOU
Uploaded on Feb 23, 2012
This talk was given at a local TEDx event, produced independently of the TED conferences.
Because we want to understand what genes are required for blood vessel development, Courtney Griffin studies certain enzymes that help turn genes on and off. These enzymes are specifically involved in relaxing DNA that is normally tightly coiled up in our cells.
The young woman below misunderstands, misrepresents the Christian theological argument "homosexuality is not natural." The Christian argument for that is
philosophical and
not scientific. Furthermore, it uses Christian philosophical
jargon from my understanding. From what I have been told anyways. So, the *jargon* is used to philosophically address what humans by nature of our higher intellects can apprehend using reason, to determine proper conduct.
So, for example, homosexuality is not only observed among the bonobos, but incestuous pedophilia as well. A Christian theologian using philosophy might argue that pedophilia, per use of human intellect, can be reasoned out to be unnatural. The "natural" being a proper
order of things, and in the Christian perspective that would align with the Christian conception of how God wants order among humans. I'm not a theologian or philosopher nor well read on the subject, so, I could be butchering to position to some degree.
(The video brings up epigenetics. I did not watch the video all the way through.)
