(2000) Turkheimer presents his Three Laws of Behavioral Genetics and explains their meaning.

Turkheimer begins by stating, "The nature-nurture debate is over. The bottom line is that everything is heritable, an outcome that has taken all sides of the naturenurture debate by surprise. Irving Gottesman and I have suggested that the universal influence of genes on behavior be enshrined as the first law of behavior genetics (Turkheimer & Gottesman, 1991), and at the risk of naming laws that I can take no credit for discovering, it is worth stating the nearly unanimous results of behavior genetics in a more formal manner."

The Three Laws are as follows:

? First Law. All human behavioral traits are heritable.

? Second Law. The effect of being raised in the same family is smaller than the effect of genes.

? Third Law. A substantial portion of the variation in complex human behavioral traits is not accounted for by the effects of genes or families.

isites.harvard.edu/fs/docs/icb.topic185351.files/Rushton-Jensen30years.pdf

(2005) Philippe Rushton and Arthur Jensen (author of, "The g Factor") conclude that IQ is the greatest indicator of future success in Western societies when inter-generational income dependence is accounted for.

They also found that IQ is at least 50% heritable and likely nearer to 80% heritable. To draw comparison, height is 70-90% heritable.

During their analysis they concluded that Whites have a minimum of 75% IQ heritability.

webspace.pugetsound.edu/facultypages/cjones/chidev/Paper/Articles/Plomin-IQ.pdf

(2004) Plomin & Spinath discuss intelligence in the wider context of genetics, genes, and genomics.

Their discussion is multi-faceted; their analysis illustrates proof of the genetic heritability of intelligence, the immense weakness of environmental explanations for intelligence, changes in heritability during development, a multivariate analysis of IQ and various testing metrics, gene expression profiling, and genomics.

This is an excellent compilatory piece.

(2009) Rushton & Jensen refute erroneous claims made about the nature of the Flynn Effect and its relationship with the Black-White IQ gap.

In their conclusions they state, "We conclude that predictions about the Black–White IQ gap narrowing as a result of the secular rise are unsupported. The (mostly heritable) cause of the one is not the (mostly environmental) cause of the other. The Flynn Effect (the secular rise in IQ) is not a Jensen Effect (because it does not occur on g)."

quick rundown?

sciencedirect.com/science/article/pii/S016028960200137X

(2001) Rushton & Rushton show evidence for racial-group differences in the form of brain size and structure, IQ, and musculoskeletal trait variation.

Their analysis shows significant variation in both the structure and sizes of the brains of Negroids, Caucasoids, and East-Asians. In addition to this, they have found differences in the skull shapes and structures of the races, alongside differences in average height and weight and all parts of the bone and muscle structures from the neck to the feet.

sciencedirect.com/science/article/pii/S0160289607000244?np=y

(2007) Shatz analyzes the relationship between IQ and fertility.

They find that IQ is negatively associated with total fertility rate, birth rate, and population growth rate. This means that higher IQ populations are less fertile than lower IQ populations.

sciencedirect.com/science/article/pii/S0160289613000470

(2013) Michael Woodley, Jan Nijenhuis, and Raegan Murphy conclude that Western IQs have declined by an average of 1,6 points per decade since the Victorian Era.

Higher IQ people are more productive, healthier, and are more creative. The reduction in IQs across the West has been met with a marked decrease in average productivity and general health despite vast increases in average wealth, nutrition and access to healthcare.

The cumulative reduction in IQ is between 12,45 and 13,35 points or roughly one standard deviation on a normal IQ bell curve. This represents an eight-fold reduction in the number of geniuses and a counter to the Flynn Effect.

The resultant decrease in IQ is attributed to dysgenics in the form of outbreeding and negative mate selection within populations. The importation of migrants of different races and ethnicities preempts the outbreeding and subsequent loss in IQ. This effect has sped up as migration has increased.

wait, can I get a quick rundown.

>Dogs have races

Do you claim this?

How is black skin a biological fiction?

How is afro hair a biological fiction?

How are wide noses a biological fiction?

How are increased rates of sickle cell anaemia a biological fiction?

How is Asian flush a biological fiction?

How are flatter eyelids a biological fiction?

All these vary between siblings too
If they make a population another race then so is brothers who look different are different races.
Therefore different skin color does not make you another race

dogs, humans, and many other animals have clearly-defined sub-species. these are defined along the lines of morphology, behavior, genetics, and geography

please see my 100+ citations, roach

Not humans.
Not dogs.
Not enough genetic drift.
I don't know what other species you talking about.


>these are defined along the lines of morphology, behavior, genetics, and geography

Yes and the biggest one is producing viable offspring.
Guess what?
It doesn't matter if you fuck an Eskimo it still makes a baby that grows and mates just as okay as you.

Why?
Who said I believe in science?

What are you implying?

Yes tomorrow is a social construct.
In space there is no tomorrow.

How much genetic drift is necessary, turk? Give me the exact amount or shut the fuck up

>viable offspring meme
This is for distinct species not subspecies. Polar bears and black bears can produce viable offspring and they still have different latin names, different behavioral patters, ffs one of them lives in the ocean and only eats meat

>How much genetic drift is necessary, turk?
please see where I demonstrate ample evidence for distinct human sub-species here:

the roach does not accept scientific evidence even though he is asking a scientific question. he's either trolling or legitimately stupid

Niggers are sub human

Is this where they say that there is more diversity within any particular race then there is between races?

Like if half of ikeas products where white and the other half black, it would be just like completely unreasonable to group them into black and white....

>or legitimately stupid
It's a fucking roach, what do you expect? These are the same people that think they live in a healthy democracy and the coup was a real danger to Erdogan and not a staged as fuck.

that's only true for white people, whites are quite varied and colorful while everyone else is basically different shades of brown and yellow

I point our flaws in reasoning.
Why would I base my worldview on a small study with a thousand individuals?
Who knows what they missed?
What of their biases?

So give me an argument in favour of race.
Explain why it (race) makes no difference to reproduction and produces viable offspring...

>>not enough genetic drift
>How much genetic drift is necessary, turk? Give me the exact amount or shut the fuck up

When they can't produce viable offspring you know it's about time to call them races or species.
In some cases genitals will be incompatible or chromosomes will be in different amounts.

>>viable offspring meme
>This is for distinct species not subspecies. Polar bears and black bears can produce viable offspring

slate.com/articles/news_and_politics/explainer/2010/05/pizzly_bears.html

Here is the reason.
>and they still have different latin names, different behavioral patters, ffs one of them lives in the ocean and only eats meat

And this makes them different races?
Eating different things is enough?

>So give me an argument in favour of race.
i gave you over 100

>Explain why it (race) makes no difference to reproduction and produces viable offspring...
i specified sub-species which is analogous to our idea of human races you illiterate roach

so i give you peer-reviewed scientific articles and you give me a link to slate.

>And this makes them different races?
>Eating different things is enough?

and now you're ignoring the mountain of evidence I presented, constructing a strawman and shooting it down

we're done here. retard confirmed. have fun in your roach motel of a country.

your stupidity is itself a fantastic case study in different human subspecies

Is this supposed to be an argument?

A dog and wolf can have viable hybrid offspring.

I choose a scientific claim that supports my position
This is what you have done with your 100 links.
You choose what you wish to believe and ignore all the rest.
So why is it a problem if I do it.
If I give you a scientific paper will you value that?
No.
Offspring yes
Viable no.

Ligers are not sterile but Tigers and Lions are separate species

>Viable no
wolfdogs can produce offspring you retard

Viable ot not?

Do you have a single source for that? I cannot find anything about them being infertile.

Of course they are viable, I have had one for 8 years now and it produced offspring too.

Ligers are sterile I believe.

wolf/dog hybrids can reproduce you idiot.
this is a well recognized fact.
it is indisputable

"Wolves and dogs are interfertile, meaning they can breed and produce viable offspring. In other words, wolves can interbreed with any type of dog, and their offspring are capable of producing offspring themselves. Although hybrids can occur naturally in the wild, they are rare because the territorial nature of wolves leads them to protect their home ranges from intruding canines such as dogs, coyotes and other wolves."
~ wolf.org/wolf-info/basic-wolf-info/wolves-and-humans/wolf-dog-hybrids/

if race is a biological fiction, how can companies analyze dna and figure out the race or mix of races of the donor? how can someone in forensics conclude the race of a person by looking at skeletal remains? why are there race specific traits, illnesses, blood types, etc? why do different races of people test differently and have different amounts of historical contribution?

to say race is biological fiction is severe ignorance.

fuck off mate.

Afro hair differs between siblings? Skin colour differs significantly between siblings? Wide noses differ significantly between siblings? Asian flush genes differ significantly between siblings?

No, they don't - your biological understanding is simply false

Asian flush (see picture related) is almost entirely exclusive to people of East Asian ancestry. It is a mutation, that has been passed down through procreation to many many people in that geographic region. But the mutation has never occurred among populations elsewhere on the planet (at least not at a rate higher than 1% of the population) - Africa, Europe, et cetera.

You fundamentally misunderstand what race is. Race refers to the different genetics that geographically separated populations have, due to tens of thousands of years of living apart. Two siblings have the same father and the same mother, so by definition they will only inherit genes present in both of those people. They *could* inherit genes of two different races (e.g. African and European) if one, or both, of the parents is mixed race, or if they are of separated races themselves. In that case, both children will be mixed-race; BOTH children will have the genetics of both races (e.g. African and European) - it is biologically impossible that one will have purely African genetics, and the other purely European genetics, because both parents genetics are used when a zygote is formed.

I suggest you read a biology book because you don't know what you're talking about.
