Evolution and Penis Size

[Padawan787 Moderator ReservePEGym Hero Find all posts View Profile Close Padawan787]

No, I'm suggesting that if there was an island made of two groups of naked people, one who pulls on their ding dongs, and one who does not, then the larger penises might provide an evolutionary advantage and carry on into the next generation just based off sexual selection.
That is, if there was an island of these two groups of people, if they were all naked (they'd have to be, otherwise how would anyone know they have a big dingaling?), if the women unanimously had a strong preference for it...
It's not complete utter bullocks to think that could happen, especially if you look at what happened to the irish elk.

Choosing a sexual partner with a large penis doesn't guarantee that this trait will be passed on. It's a trait that is passed on from the mother's side.

A woman could procreate with a guy who has a 12" penis and give birth to a child with a micropenis, the father's size isn't a part of the equation.

This may not be the case with antlers (I don't know ), but selecting a partner for penis size wouldn't necessarily result in an overall increase in the penis size of a population over time.

You guys bring up a good point. My elk comment then really is out of place, then.

I thought that the body would adapt to environmental changes. It seemed likely to me that if you had a group of people all enlarging their penis and them carrying on their genetics, that a shift would be made. What you guys are saying that it's the behaviour that would be passed down, and not the peen

You are right and that the body will adapt to environmental changes, but it has to adapt at the DNA level.

The DNA makeup resulting in the ability to enlarge the penis would possibly be carried to the next generation. It may be arguable that the amount of inner penis is determined by genetics.

The behavior would most likely to taught to the next generation. This is definitely a norm for most mammals.

I'm not religious in the traditional sense it was not part of my family background and of my father's & I'm a chip off the old block.

"Authorised by whom?" is a very good question, I'm glad you've asked. You need to (and please do so) investigate that for yourself. Sometimes we need to arrive at conclusions because when they are given to us the whole point can be missed.

Take some African tribes for example who lengthen their necks by using neck rings, the results of this practice doesn't alter their genetics and so it isn't genetically passed down.

It's just a form of body modification that they practice because they find long necks desirable.

^ great for us PE guys if we like deep throating

I think there COULD be more subtle dynamics going on. In fact the genetics could be effected as follows: stretching necks may create damage in some specimens perhaps leading to paralysis. Genes that protect against such injury, or preclude damage by providing a pre-made longer neck could dominate over generations.

I actually know quite a bit about research funding. I've been involved with EU research grant commissions, and have worked on grant applications for privately and publicly funded research projects.

If an idea can be patented and is profitable, it will be used, there is no "authorization" needed.

In the EU most public grants state that the information gathered from the research project must be made publicly available. (France is a specific example)

Obviously, NDAs come into play on certain private projects, but so long as something isn't patented nothing is stopping someone else from coming along and researching it themselves.

I'm glad for you. It must e interesting to see how these things work. What's NDA?

The only trait that would be carried for the people who pull their penises is the ability to pull their penises further. Genetic code must be altered for a change to happen. PE is is only a modification and will NEVER change DNA structure.

This is not right. If you are seriously interested in genetics, look into epigenetics. Very interesting newer field, however, the field is still in a complete infant stage (probably embryonic stage would be a better term). Epigenetics will be the next big thing, and it will probably be the biggest advancement of biology in history. True individual genetic engineering may be possible, just don't hold your breath for it in our lifetime.

One example is that, it is now being discovered that heterochromatin may be the supercomputer of our DNA and not the junk it once was thought. This type of issue is encompassed by epigenetics. However, frankly we are not capable of understanding standard genomes let alone the complexities of minor chemical alterations of DNA (essentially what epigenetics is suppose to study).

I am speaking of natural selection not cooking the DNA. I agree, but if we will not see it in our lifetime, is it worth debating? Yes it is, but not here.

Epigenetics is the next big thing. Makes you think twice about smoking a joint or drinking a beer or eating preservatives.

Also, "evolution theory" is what it says on the tin... a THEORY at best. When it comes to humans I personally believe that eugenics in some way or an other has a lot to do with how we look, a sort of genetic engineering. I'm not talking labs and white coats but keeping infants based on certain physical traits. Like keeping the lighter skinned offspring and disposing of darker ones or mating people with certain "favorable" physical or behavioral traits, or killing off the week as we have seen in Sparta. I think the Masay tribe in Africa for example deliberately bred and/or kept taller infants. So you need to look at this question in the light of man made engineered qualities though I'm not aware of anyone deliberately breeding little John Holmes lookalikes.... certainly my parents didn't.... those bastards

What are you talking about? Is this that tired "only a theory" crap? Go and look up the definition of the word "theory".

And as for eugenics...keeping the lighter-skinned offspring...um, yeah OK, whatever dude. :-/

What that shows is that some women, in the USA in 2013, like dudes with bigger dicks. It's hardly a convincing case for an evolutionary advantage.

What I have read, though, is that shape matters. The classic 'helmet' shape of the human glans isn't found in other mammals, and some researchers think it's because the shape evolved to help scoop out the last guy's semen from the vagina in order to increase the chance of one's own jizz leading to an impregnation. Which is surely some food for thought whenever you hear conservative types going on about the louche morals of young people "these days"! Some people even did an experiment that involved putting pretend semen in a pretend vagina and then fucking it with various pretend penises attached to a crankshaft (hur hur, I said 'shaft!') - the penises were all the same size but had various differently shaped heads. The one that was shaped like a read penis successfully scooped out most of the 'semen', while the one that had a plain round knob on the end was pretty useless and left most of the 'semen' where it was.

So there you go. Pretty interesting, I thought.
