I'm still waiting for you to read the articles that were posted.

In case you didn't get it, I was being sarcastic. Since you're here, let's hear your solution to this race identification issue.

But why?

There is no fundamental biological principle which states that is where the lines for these divisions should be drawn. The decision to drawn the line there is based on convenience. That is largely the crux of this discussion: Whether or not the divisions are natural or if the have just been reified through use. 

And no, skewed allele frequencies are not the key to identifying race. If that were true, we would consider people from East Finland to be a different race than West Finland. As it turns out, through skewed allele frequencies, genetic technology can actually determine ancestry location within a few hundred kilometers. Skewed allele frequencies are simply natural artifacts which present themselves in any large population. 

I found a few interesting articles on the topic that I wanted to bring up:

Evidence for Gradients of Human Genetic Diversity Within and Among Continents

https://pdfs.semanticscholar.org/959a/62f7b57dba3f38d183e6caecbe39a05c19d2.pdf?_ga=2.169619745.1273437384.1519162892-1643875267.1519162892

This article is a direct response to the Rosenburg (2002) article you posted yesterday. Essentially, what it is stating is that the "distinctness" of the populations determined by Rutherford (which already exist on shaky footing as a stand-in for race, for the reasons discussed above) is largely due to the incomplete nature of his population sets. By taking a more even sampling from across the globe, we find that humanity doesn't exist in distinct chunks but instead exist as a gradient, or cline. 

"Using a homogeneous sampling strategy and a model in which allele frequencies in the different inferred populations are allowed to be independent, we find a stable and reproducible representation of human genetic diversity in which the extent of admixture between individuals in Eurasia and the Americas changes continuously with geographical distance without any major discontinuities"

"on a worldwide scale, clines are a better representation of the human diversity than clades, and that continents do not represent more substantial discontinuities in such clines than many other geographical and cultural barriers"

Population Genomics and the Statistical Values of Race

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4756148/

This article discusses similar ideas, outside of the context of Rosenburg. It shows that the "cluster" effects some studies demonstrate is likely to be an artifact of flawed sampling, it covers the statistical analyses dealing with the division of a species into race and demonstrates that the difference are often not stastically significant and are evolutionarily meaningless, and concludes that the idea of "race" has no basis in biological reality.

"Adopting an interdisciplinary approach, it demonstrates that the hypothesis that attributes the clustering of human populations to “frictional” effects of landform barriers at continental boundaries is empirically incoherent"

"what counts as “biological reality” of human races is elusive, ranging from “trivial” to “obscure,” and often construed in a non-Darwinian biological framework"

"In Darwinian classification (but also in phylogenetic systematics), a biological grouping of organisms that does not meet [certain criteria] is referred to as a wastebasket taxon. It is so called because it is evolutionary unordered and functions in science merely as a “warehouse kind” that taxonomically lumped together disparate organisms having no objectively definable evolutionary relationship. Wastebasket taxa lack natural reality and granting them objective biological existence constitutes an erroneous attribution of ontological status called the fallacy of reification"

“A classification that takes into account evolutionary relationships and the nested pattern of diversity would require that Sub-Saharan Africans are not a race because the most exclusive group that includes all Sub-Saharan African populations also includes every non-Sub-Saharan African population…”

" the cline model maps continuous genetic gradation in a dataset and indicates that there is no natural break in a population's genetic profile "

"These characteristics are inherently true, the structures that scientists made (based on these characteristics) are not."

what structures?

"Why is it nonsensical?"

does a platypus have wings? does it have feathers? no? then how could it be a bird if we all agree that birds possess wings and have feathers?

"you just drew a clear line with elephants, why?"

i'd like an answer to this question

"The four corners obviously have a different colour, right? But can you draw a line where one colour starts and another begins?"

clouds, trees, people etc etc etc all appear to meld into one at great distances from the observer, does that mean that there is no distinction between these things?

""scientists categorise and label phenomenon THAT ALREADY EXIST when it comes to biology""?

No. The animals exist. The structures don't."

...

i'll ask again wings existed before scientists called them wings right? if we can agree on that then we agree that scientists catergorised and labelled something that already existed right?

"Because if you understand how evolution works, you should also be able to understand that all creatures are related to eachother"

so why don't elephants swim with fish in schools?

I say that each school should hire a team of geneticists and researchers.  Through a combination of extensive genetic testing, family interviews, and archival research, we will be able to really nail a student's ethnic heritage.  

I figure that a school of about 1000 students could make due with a team of 4-5.  The median salary would be in the realm of 65K a year, so schools may have to sacrifice a few teachers, cut a few after school programs, or limit investments in technology for students.  However, this is a small price to pay for the peace of mind that comes with knowing all students' races are accurately recorded. 

Now we're talking, we're going to create so many geneticist and research jobs! As for the the teachers, eh they're all cultural Marxists anyways, who needs 'em.

Lets use this color thing as an example.

Biologists now classify species according to to their genes. From those they can see what elvolved into what, which species are animals, plants, archae etc. and how close different species are from each other. The platypus could have wings, beak and lay egg and it would´t still be nowhere near birds according to its genes. 

As for the races think about that color thing. Lets say that we have that for every species and the clearly different colors represent different races in that species. For dogs the yellow might represent chihuahua and the green could golden retrievers, two clearly distinct races. Now on to humans, look at a small section from the middle, humans only have that so there are differences, but they are too minor for us to have proper races (we still could have distinct races at some point). 

Should the opinions of random people change the way the taxonomic stucture is build? And what would happen if they changed it? 

It wouldn´t really change reality, but the system would change and former races and everything under it would have to be called something else and would have to be changed. Still people wouldn´t be happy as we would then have to have huge number of human races for example, at least two races of finns. People wouldn´t regognize different finns by just looking at them, but would need genetests to differiate them.

It would all be pointless and nobody would be happy.

People want things to be simple, visible and easily defined. More often than not  things just aren´t like that.

That sounds like a good idea, as long as its only in USA as they already have a president who would certainly approve that. Also the schools there are generally already fukked up so it wouldn´t matter that much, just more of the same old same old, making america great again ;D

1.  Then would you agree that since penguins have flippers and not wings they are not birds? 
2.  This cannot be a serious question ... can it? 

penguins don't have wings? really? so what are those objects attached to their shoulders?

so am i to assume that like him you believe that animals cannot be sorted into groups?

"This cannot be a serious question ... can it? "

you find him claiming that animals cannot be sorted into groups to be a valid proposition?

you were being sarcastic about what? you claiming that hitler was a capitalist?

with regards to race identification, it depends on the context
