We must define race, culture, environment and genetics to adequately answer these questions.
1.) Race:
A.)
: any one of the groups that humans are often divided into based on physical traits regarded as common among people of shared ancestry.
B.) a group of people sharing a common cultural, geographical, linguistic, or religious origin or background
C.) a group within a species that is distinguishable (as morphologically, genetically, or behaviorally) from others of the same species
So a group of people that share the same or similar physical features such as height, weight, body composition, muscle, bone density, beliefs, practices DNA, intellect, backgrounds, language, culture, etc.
2.) Genetics:
A.) the study of heredity and the variation of inherited characteristics.
B.) the genetic properties or features of an organism, characteristic, etc.:
C.) A group within a species that's distinguishable (as morphologically, genetically, or behaviorally from others of the same species)
So the study of human's behaviors, DNA, physical characteristics, and other features.
3.) Culture:
A.) the
attitudes,
behavior,
opinions, etc. of a
particular group of
people within
society:
B.) The way of
life,
especially the
general customs and
beliefs, of a
particular group of
people at a
particular time:
A group of people's beliefs, behaviors, ideology, practices, actions, etc over a specific period of time.
4.) Environment:
A.) the
air,
water, and
land in or on which
people,
animals, and
plants live:
So essentially your geographic locations.
From these definitions alone it's obvious that our racial background combined with the environmental factors, and culture are the main factors for our genetics. Another factor is one's own personal drive to overcome adversity, obstacles, and to learn and grow during one's own life.
We use DNA to determine one's genetic background or their racial background. Genomic DNA testing determines your phenotype and the mitochondrial DNA (mtDNA) and Y-DNA haplogroups, along with many other features.
As for comparing humans to dogs or other animals that's a completely different discussion because we were discussing the differences within the same species and not the differences between other species. With that being said, they do have the capacity to learn and increase their intellect as well but have a lower baseline and overall lower potential than humans to increase their own intelligence.
For example Koko the Gorilla who was taken in by a white female when she was very young and this lady taught her many things including how to communicate with sign language. Koko learned over a thousand signs and even developed a sense of humor.
She was given different test to determine her level of intelligence over time. The tests given to Koko the gorilla were Cattell Infant Intelligence Scale, Peabody Picture Vocabulary Test, Ravens Progressive Matrices and Wechsler Preschool and Primary Scale of Intelligence. Chapter 14 of this
document gives a description of those IQ tests. Research also showed that Koko was able to demonstrate some of the techniques required for abstract thought. Koko the gorilla has a tested IQ between 70 and 95 on a human scale..
I agree white or Caucasian genetics have decreased over time more so than any other race and it started at the turn of the 20th century and increased rapidly after WWII. The main reason for white genetics decrease over this time period has been due to forced multiculturalism within their own countries which led to breeding with other races to make their genetics impure. Combine this with the destruction of their food, water, air, and culture along with things like vaccinations, and medications. This is due to the Zionist Jew with their intentional measures to collapse our society and to decrease our genetics with policies, money supply, medicine, water supply, food supply, air and even the frequencies surrounding us have ll been intentionally altered to destroy our genetics more so than any other race.
The average German IQ before WWII was 107 and the average in some German cites was around 114. Germany was the most advanced nation on earth during this time period.
Lastly, you go on to say western whites have the worst genetics and Arkians have the best. Who in the hell are the Arkians? What metrics are you using to determining the quality of one's genetics?
