Polygamy left its mark on the human genome

Selective pressure is applied by the environment. Thus “favorable” means “confers a reproductive advantage in that environment”. Selection is not random, selection is the predictable consequence of differential reproductive success. Thus under high heat conditions high temperature alleles are selected for.

[LiteKeeper]

The changes are so slight in any given event, that "confers a reproductive advantage" can't be defined by the organism itself. This is again just story-telling.

And still my original question goes unanswered: How does an organism divide functions into two different organisms which rely on each other? And which must keep pace with each other during the alleged "evolutionary" life of any given species. One organism is genetically independent from the other, yet totally dependent upon the other for reproduction. This amounts to an amazing amount of complexity. Each organism must "evolve" part, but not all, of the functionality. And to reproduce that functionality would have to be there from the beginning, or it would not be able to reproduce to respond to the "selective pressure" that is allegedly "applied by the environment."

It’s infuriating when liberals advance the idea that simply impregnating females is all that matters in human survival.

It ignores the most obvious difference between humans and the rest of creation: Our long, long period of helplessness. Animals can either move or defend themselves within days of being born, while humans are more or less helpless for a couple of years. What this means is that two-parent care is vitally important for humans—at least as important as impregnation itself. Animal fathers may impregnate and run, but if human fathers acted that way throughout history, the human race would not exist. We would all have been literally devoured by wolves.

They can develop together in a hermaphrodite until they are complete specialized sexual organs, male and female, then separate. We see simple hermaphrodites, more complex hermaphrodites, and ourselves who start out as hermaphrodites and then differentiate.

Your insistence that they had to develop separately has no basis.

[LiteKeeper]

Do you honestly believe this...of every bisexual species on earth? Really? And where is the evidence for this absurd assertion?

[allmendream]

In the journal I sourced, in hermaprhoditic species still extant upon the earth, and in our own DNA and development in that we start out as hermaphrodites.

You know nothing about the subject and yet insist sexual organs had to develop seperately, completely ignoring that the earliest sexually reproducing organisms we know of are all hermaphrodite.

And then you are incredulous about it.

Funny! ;)

[LiteKeeper]

What you acknowledge that...
2. ...in every instance of a species reproducing by means of heterosexual activity, there are two different individuals required: a male and a female?
2. ...if there are two different individuals, even if at some point there was only one (which I do not accept), at some further point, the one had to divide into two?
3. ...that there would need to be some change after the two divided: loss of at least part of the function being carried on by the other?
4. ...that in every instance of heterosexual reproduction, both individuals would have to be fully functional in order for any off spring to carry on the “evolution”?
5. ...that your journal has not explained how that happened, when it happened, or even that it actually happened?

[allmendream]

You are wrong and now your just being silly about it.

Learn something.

Gender-Bending Barnacles Grow Huge Penises in Rough Waters

Over time the human genetic pool has become increased with advancing numbers of mutations which have weakened genes causing myriads of genetic orientated diseases. In the beginning of time the gene contained very few mistakes so that multiple marriage partners and intrafamily marriages did not give way to weak individuals.

Apart from intervention by God we are destined to have greater and greater amounts of genetic mistakes and problems, eventually disappearing from existence. Thank God, this will not happen due to Christ's return, bringing the renewing of all things.
