The left's rejection of science

[Rigby5]

It is obvious that DNA can not control gender directly. Gender is outside of any one cell. So forget the simplistic false impression you memorized in the past. It is wrong.

So all of society is “wrong” (including all doctors and scientists). The only one who is right is Rigby5.

Sex determination. A baby's sex is determined at the time of conception. When the baby is conceived, a chromosome from the sperm cell, either X or Y, fuses with the X chromosome in the egg cell, determining whether the baby will be female (XX) or male (XY).

See...at the time of conception...the fetus has no hormones. That doesn’t occur until much later. You’re dead wrong. And really stupid.

Sexual differentiation in humans - Wikipedia

How does your mistaken beliefs account for things like hermaphrodites? (both genitalia)
Of course the fetus has hormones.
Without hormones it could not divide, multiply, or grow more cells.

From your own link, which you really, really should at least read:

{...
A fetus doesn't develop its external sexual organs until the second month of pregnancy—seven weeks after conception. The fetus appears to be sexually indifferent, looking neither like a male or a female. Over the next five weeks, the fetus begins producing hormones that cause its sex organs to grow into either male or female organs. This process is called sexual differentiation. The precursor of the internal female sex organs is called the Müllerian system.
...}

The process of growth, especially the growth of sex organs, is entirely and completely controlled by hormones. The fact these hormones are usually produced by RNA transcription from DNA, is not relevant.

—seven weeks after conception. The fetus appears to be sexually indifferent, looking neither like a male or a female. Over the next five weeks, the fetus begins producing hormones

Bingo! It takes 12 weeks (7 weeks after conception, then around 5 weeks after that) for the fetus to begin to produce hormones.

Chromosomes dictate nothing

What a scientific genius. "Chromosomes dictate nothing, HORMONES dictate it." And what, Gregor Mendel, dictates the hormones?

This is what we are dealing with these days. The left has dissolved into a bunch of ignorant minions who not only reject science, they are actually unaware of even basic science. God help us.

I'm just waiting for one of these brain trusts to ask who the hell Gregor Mendel is.

 

[Cecilie1200]

Can you physically tell much about when puberty starts by just looking physically?

Uh...yes (dumb ass). Acne. Pubic hair. Underarm hair. Hips widen.

I never said anything about thinking, but clearly something 13 years after the physical equipment develops, hormones can be quite different.

The ignorance of the left in all of its glory. Hormones do not dictate gender, dumb ass. Chromosomes dictate gender. And chromosomes don’t change. Ever.

Sorry, but that is totally and completely wrong.
DNA transcribes RNA, that then produces hormones.
And then it is the hormones that determine everything about how the body grows, including gender.
Gender is outside of any cell, and is a group organization of cells.
Which can ONLY be done by hormones.
DNA can't do anything outside of its single cell.
All body growth, positioning, shape, and anything multicellular, is hormones, ALL hormones.

What's funny is that you cut and pasted something scientific that you THOUGHT supported your contention, while it actually said the exact opposite of what you did.

Chromosomes dictate nothing.

Folks...you just can't make this stuff up. Here is a progressive egregiously denying science with the mind-numbing statement "chromosomes dictate nothing". Wow. Just....wow.

Females have an XX pair of sex chromosomes, and males, an XY pair. A baby’s gender is determined by the sperm cell that fertilizes a woman’s egg. Sperm carry one sex chromosome, either a Y (male) or X (female).

How embarrassing for you. This is basic science taught to middle school students.

How a Baby's Gender is Determined | XX Gender XY | Gender Baby

That is incredibly ignorant.
How is the DNA inside one cell going to go to other cells and make them differentiate to become part of a penis or part of vagina.
DNA can't and does not do that.
All the DNA does is transcribe RNA, that then produces hormones, and then the hormones can leave the cell and interact with other cells in order to produce organs.

I'm actually embarrassed for you at this point. If you understand genetics so little, you should never, EVER speak about them where people can hear you. It would be less public humiliation if you just walked into work buck naked.

Wrong, things like acne, underarm hair, and pubic hair are not gender specific.
We were talking about being able to tell which gender when puberty starts.
And hip widening is not universal or gender specific.

Chromosomes dictate nothing.
Hormones dictate everything, and hormones can change due to environmental things like pesticides, illness, or other sources of hormones.

What a scientific genius. "Chromosomes dictate nothing, HORMONES dictate it." And what, Gregor Mendel, dictates the hormones? Yes, they can be affected by pesticides and illness and such, but are you suggesting that every human who has ever lived to adulthood on this planet went through puberty because pesticides or illness triggered their hormones?

In the immortal words of Bugs Bunny, "What a maroon."

And how do you propose for DNA to coordinate multiple cells to make up a colony organ?

Just . . . wow. I can't even . . . wow.

How DNA Works

I just . . . no. I can't. Wow.

Fine.
The point is that DNA can contact only within the nucleus, and therefore multi cellular growth, such as sexual organs, has to be directed remotely by hormones. And external hormones, such as from pesticides, can easily over ride the naturally produced ones, to either alter the sex organs produced in the fetus, or later how puberty develops. And the 13 year interval between, clearly also provides great opportunity for them to be mismatched.

Mendel only made external observations.
He did not know the internal mechanisms or details, that we know now.
And he did not have artificial hormones available to be able to over ride the DNA produced hormones like we have now with pesticides.
This discussion is not about how it used to be naturally, but now it now has completely changed, due to things like radiation, pesticides, viruses, etc.

My POINT was that DNA does not directly control the sexual dimorphism.
It can't because the DNA is locked up inside the nucleus of the cell and sexual dimorphism requires something to coordinate between many cells.
So DNA normally controls sexual dimorphism through the production of hormones.
And the problem with that is those natural hormones can easily be interfered with or over ridden by other externally applied factors, like pesticides.

And in addition, my point is that you can not tell from looking at sexual dimorphism, of either penis or vagina, what the DNA actually contained in terms of XX or XY. Nor can you tell whether or not when puberty happens, whether or not it is in accord with either the DNA or the previous sexual dimorphism.

And most important of all, is that clearly then the fact there are absolute physical mechanisms that can cause these incongruities to occur means that the sexual orientation conflict do not have to be just imagined or made up. These people who claim to have some sort of mismatch likely are accurately telling the truth. It is likely a mismatch did occur between the 13 year gap between fetal development and puberty.

So that has to be remotely controlled by the DNA production of hormones.
And the whole point is that hormones from the environment, such as pesticides can and do easily over ride the hormones the DNA produces.
So anyone who does not understand that an XY male fetus can grow a vagina and an XX female fetus can grow a penis, does not understand biology.

Do you understand that all cells contain exactly the same DNA blueprints, but that something else has to coordinate between cells, so that cells can differentiate? Ask yourself why a cell turns into a heart muscle cell while another turns into a brain cell? That coordination can not come directly from the DNA within the cell, because that is identical in all cells. There has to be a mechanism that tells a cell what type it should be, based on what cells it is next to. What is this communication mechanism, and can it be externally interfered with?

 

[P@triot]

Ask yourself why a cell turns into a heart muscle cell while another turns into a brain cell?

Ask yourself why you continue to reject science. Ask yourself while every single living scientist, PhD, and high school dropout understands that XX or XY chromosomes determines gender, while you deny it.

Ask yourself why you insist on embarrassing yourself.

Here are the parts of my link you SHOULD have been reading and attempting to cram into your petrified excuse for a mind, instead of cherrypicking for sentences you could pretend support your insane notion that DNA has nothing to do with puberty.

From the first page:

Changes in the DNA of cells in multicellular organisms produce variations in the characteristics of a species.

From the second page:

DNA is one of the nucleic acids, information-containing molecules in the cell (ribonucleic acid, or RNA, is the other nucleic acid).
The information in DNA:

• guides the cell (along with RNA) in making new proteins that determine all of our biological traits
• gets passed (copied) from one generation to the next

From the fourth page:

DNA carries the information for making all of the cell's proteins. These proteins implement all of the functions of a living organism and determine the organism's characteristics.

From the fifth page:

DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein.

Proteins have many functions:

• Enzymes that carry out chemical reactions (such as digestive enzymes)
• Structural proteins that are building materials (such as collagen and nail keratin)
• Transport proteins that carry substances (such as oxygen-carrying hemoglobin in blood)
• Contraction proteins that cause muscles to compress (such as actin and myosin)
• Storage proteins that hold on to substances (such as albumin in egg whites and iron-storing ferritin in your spleen)
• Hormones - chemical messengers between cells (including insulin, estrogen, testosterone, cortisol, et cetera)
• Protective proteins - antibodies of the immune system, clotting proteins in blood
• Toxins - poisonous substances, (such as bee venom and snake venom)

Oh, look, there's your beloved hormones on the list, being determined by the DNA YOU claim has nothing to do with the process, and which I already told you was the root cause of hormones.

From the sixth page:

Building proteins is very much like building a house:

• The master blueprint is DNA, which contains all of the information to build the new protein (house).
• The working copy of the master blueprint is called messenger RNA (mRNA), which is copied from DNA.
• The construction site is either the cytoplasm in a prokaryote or the endoplasmic reticulum(ER) in a eukaryote.
• The building materials are amino acids.
• The construction workers are ribosomes and transfer RNA molecules.

So there you have it. You are a drooling mouthbreather whose teachers in public school should all be horsewhipped, and you should never, ever presume to speak around other adults on any subject more intellectual than "You want fries with that?"

My bill for your fucking remedial biology lesson will be in the mail, shit-for-brains.

Pesticide atrazine can turn male frogs into females

Pesticide atrazine can turn male frogs into females
By Robert Sanders, Media relations | MARCH 1, 2010

Atrazine, one of the world’s most widely used pesticides, wreaks havoc with the sex lives of adult male frogs, emasculating three-quarters of them and turning one in 10 into females, according to a new study by University of California, Berkeley, biologists.

The 75 percent that are chemically castrated are essentially “dead” because of their inability to reproduce in the wild, reports UC Berkeley’s Tyrone B. Hayes, professor of integrative biology.

“These male frogs are missing testosterone and all the things that testosterone controls, including sperm. So their fertility is as low as 10 percent in some cases, and that is only if we isolate those animals and pair them with females,” he said. “In an environment where they are competing with unexposed animals, they have zero chance of reproducing.”

The 10 percent or more that turn from males into females – something not known to occur under natural conditions in amphibians – can successfully mate with male frogs but, because these females are genetically male, all their offspring are male.

“When we grow these guys up, depending on the family, we will get anywhere from 10 to 50 percent females,” Hayes said. “In a population, the genetically male females can decrease or wipe out a population just because they skew sex ratios so badly.”

Though the experiments were performed on a common laboratory frog, the African clawed frog (Xenopus laevis), field studies indicate that atrazine, a potent endocrine disruptor, similarly affects frogs in the wild, and could possibly be one of the causes of amphibian declines around the globe, Hayes said.

Hayes and his UC Berkeley colleagues report their results in this week’s online early edition of the journal Proceedings of the National Academy of Sciences. In last week’s issue of the Journal of Experimental Biology, Hayes and colleagues published a review of the possible causes of a worldwide decline in amphibian populations, concluding that atrazine and other hormone-disrupting pollutants are a likely contributor because they affect recruitment of new individuals and make amphibians more susceptible to disease.

“These kinds of problems, like sex-reversing animals skewing sex ratios, are much more dangerous than any chemical that would kill off a population of frogs,” he said. “In exposed populations, it looks like there are frogs breeding but, in fact, the population is being very slowly degraded by the introduction of these altered animals.”

Some 80 million pounds of the herbicide atrazine are applied annually in the United States on corn and sorghum to control weeds and increase crop yield, but such widespread use also makes atrazine the most common pesticide contaminant of ground and surface water, according to various studies.

This also happens to higher order organisms, including humans.
DNA is NOT at all final. All DNA does is transcribe certain hormones, but if other contrary hormones are present in sufficient quantity, then the fetal development will be contrary to what the DNA itself would have caused.

You clearly do not know how to read.
I never said DNA had nothing at all to do with it.
Normally DNA creates the hormones that determine sexual organ development.
My point was that DNA then is not directly controlling the process, and it is indirect, through the hormones it produces.
And the problem with that is external sources of hormones, such as pesticides, can and do sometimes over ride the DNA produced hormones, to cause a fetus to develop sexual organs CONTRARY to what the DNA would have mapped to.

So then NO, DNA does not always dictate gender.
If influenced by external hormones in sufficient quantity, then a fetus will not be according to the DNA.

So their fertility is as low as 10 percent in some cases, and that is only if we isolate those animals and pair them with females,” he said. “In an environment where they are competing with unexposed animals, they have zero chance of reproducing.”

The 10 percent or more that turn from males into females – something not known to occur under natural conditions in amphibians – can successfully mate with male frogs but, because these females are genetically male, all their offspring are male.

“When we grow these guys up, depending on the family, we will get anywhere from 10 to 50 percent females,” Hayes said. “In a population, the genetically male females can decrease or wipe out a population just because they skew sex ratios so badly.”

Though the experiments were performed on a common laboratory frog, the African clawed frog (Xenopus laevis), field studies indicate that atrazine, a potent endocrine disruptor, similarly affects frogs in the wild, and could possibly be one of the causes of amphibian declines around the globe, Hayes said.

Hayes and his UC Berkeley colleagues report their results in this week’s online early edition of the journal Proceedings of the National Academy of Sciences. In last week’s issue of the Journal of Experimental Biology, Hayes and colleagues published a review of the possible causes of a worldwide decline in amphibian populations, concluding that atrazine and other hormone-disrupting pollutants are a likely contributor because they affect recruitment of new individuals and make amphibians more susceptible to disease.

“These kinds of problems, like sex-reversing animals skewing sex ratios, are much more dangerous than any chemical that would kill off a population of frogs,” he said. “In exposed populations, it looks like there are frogs breeding but, in fact, the population is being very slowly degraded by the introduction of these altered animals.”

Some 80 million pounds of the herbicide atrazine are applied annually in the United States on corn and sorghum to control weeds and increase crop yield, but such widespread use also makes atrazine the most common pesticide contaminant of ground and surface water, according to various studies.

This also happens to higher order organisms, including humans.
DNA is NOT at all final. All DNA does is transcribe certain hormones, but if other contrary hormones are present in sufficient quantity, then the fetal development will be contrary to what the DNA itself would have caused.

P@triot, take a moment to really absorb the irony of being told that you "do not know any science" by a person who then goes on to explain at length why DNA has nothing to do with an individual's characteristics or development. Rather breathtaking, no?

Ask yourself why a cell turns into a heart muscle cell while another turns into a brain cell?

Ask yourself why you continue to reject science. Ask yourself while every single living scientist, PhD, and high school dropout understands that XX or XY chromosomes determines gender, while you deny it.

Ask yourself why you insist on embarrassing yourself.

You really do not know any science and have not asked any one who does know science.
Here is an example that proves you wrong once again.

Pesticide atrazine can turn male frogs into females

Pesticide atrazine can turn male frogs into females
By Robert Sanders, Media relations | MARCH 1, 2010

Atrazine, one of the world’s most widely used pesticides, wreaks havoc with the sex lives of adult male frogs, emasculating three-quarters of them and turning one in 10 into females, according to a new study by University of California, Berkeley, biologists.

The 75 percent that are chemically castrated are essentially “dead” because of their inability to reproduce in the wild, reports UC Berkeley’s Tyrone B. Hayes, professor of integrative biology.

“These male frogs are missing testosterone and all the things that testosterone controls, including sperm. So their fertility is as low as 10 percent in some cases, and that is only if we isolate those animals and pair them with females,” he said. “In an environment where they are competing with unexposed animals, they have zero chance of reproducing.”

The problem is you are not reading well and clearly do not understand what I wrote.
I never said that "DNA has nothing to do with" sexual development.
My POINT has always been that DNA can't do it directly, and instead has to remotely control sexual development through hormones, and the problem with that is externally applied hormones, such as from pesticides can over ride the DNA hormones.
So a mismatch between DNA and actual sexual organ development is possible.
Which means you can't look at fetal development, such as penis or vagina, and know whether the DNA is XY or XX.
There is NOT a one to one correspondence.
And that confusion is even more complicated by the fact the mismatch can end or begin also in the 13 year interval between conception and puberty.
So anyone saying that DNA is absolutely definitive, and is claiming XY is male and XX is female, is just totally and completely wrong.
DNA normally and commonly controls, but does not have absolute control, so in SOME percentage of the population there WILL be a mismatch between DNA and actual gender.

And this is not just from pesticides.
There are dozens of illnesses, nutritional causes, etc. that can cause this mismatch.

And the fact these gender problems exist is also easily proven by simply remembering that hermaphrodites exist, with the physical genitalia of both genders. There is no way DNA can do that. But yet it happens, so there has to be the potential for the DNA to be over ridden and something else happening, contrary to the DNA. But we also know there are DNA combinations such as XYY, and XXY, that you have not even begun to take into account. It is just totally and completely wrong to believe there is ONLY XX and XY, or that DNA is absolutely definitive. It clearly can NOT be.
