What is it that makes people different from other countries?
Topic: Thesis meaning wikipedia
June 25, 2019 / By Branden Question:
I mean physically. I know that skin pigment has to do with sun exposure, but what about all the other things? Like what causes typical black Asian hair to be stringier than curly black Spanish hair, or what originally caused hair to be red. Why do black Africans typically have a flat, wider nose than some whites? Obviously theses traits are passed down from our parents, but they all had to originate and change somewhere. What I am asking is: how did we change, and what causes the change.

genetically we all started out black on the African continent.
everything beyond that is evolution based on enviromental factors. roughly 1.2 million years ago we all looked like Africians of today.
for example as you & others have mentioned skin pigmentation is based on melanin to protect from skin cancer.
"The mutation resulting in light skin is currently estimated to have originated among Europeans some 6,000 to 12,000 years ago"
Melanin is also present in hair, which explains the difference between "black: hair, "Asian" & "Caucasian" hair. based on where people settled, they adapted.
curly hair tends to be drier that other types, some antyhropologists believe that it became "evolutionarily necessary to expel heat from the body at a more rapid rate" & that hair types involve the body's ability to sweet & cool down.
"Red hair appears in people with two copies of a recessive gene on chromosome 16 which causes a change in the MC1R protein. It is associated with fair skin color, freckles, and sensitivity to ultraviolet light, as the mutated MC1R protein is found in the skin and eyes instead of the darker melanin. Estimates on the original occurrence of the currently active gene for red hair vary from 20,000 to 100,000 years ago"
noses follow the same model - one of the purposes of the nose if to warm the air that we breathe before it hits our lungs & to clean that air that we breathe. flat and wide must have worked better in Africa.
change is caused because we adapt to what works best in our enviroment to increase our chances for survival. the change happens on the genetic level.

Originally Answered: What makes the current American healthcare system better than European countries?
When you hear Republicans and conservatives brag that we have 'the best healthcare system in the world', what they really mean is that our healthcare system creates more wealth, more profits, than any other in the world. Which it certainly does!
To conservatives, profit and wealth creation is the primary purpose of our health care system. The handful of enormously powerful corporations who OWN the system are big campaign contributors, so the health care system also generates campaign funds, which is 'good' to any politician. The actual provision of health care is seen as just an unfortunate 'cost of doing business', to be minimized however possible.
The US healthcare system is unique in this way. In every other democratic, developed country, the main purpose of the health care system is to provide health care!
But here in the US, even a 'socialist marxist communist' like Obama wasn't able to propose any plan that could hurt the profits of the corporations. That was even HIS first priority!
It's ancestrial DNA. Every human started in Africa (proven without a doubt by DNA). From there, some people migrated. After a time (thousands of years), people began to breed with people who had the same features. (Sort of like families who are tall and marry into other tall familes, will generally have tall children). These DNA changes are called DNA Mutations and there are only a handful in the history of mankind). The Sorenson Molecular Genetic Foundation did a DNA study that explains all of this. They have a really good site about it that you can go to, to learn more. They have a good video that explains it all. Here's the link...........

DNA is showing that everybody's ancestry began in Africa, even Scandinavians. It is believed that there were mutations and some types of people could not survive in certain areas and died out. Our ancestors were nomads at one time.
An example. The sun is rich in Vitamin D.
The minimum amount of Vitamin D a black African requires is the maximum amount of Vitamin D someone of northern European background should have. Today it doesn't make as much difference as we have clothing and housing to block out sunlight and also there are vitamin supplments for people who need more Vitamin D.

What about protection stress households that are shipped everywhere in the planet? and they are no longer "movie star millionaires": some protection stress households bypass each and every 3-4 years. the toddlers don't have a "homeland" nor have they were given a "authentic class from which to graduate". They get their "roots yanked up each and every 3-4 years" and characteristic genuinely NO say contained in the matter in any way. My dad change right into a severe score naval officer, and we did not bypass yet once using his "taking area in the better ups". although, I said youngsters that were shuffled throughout this planet, and adapted. even as searching again, now I see WHY my father and mom discouraged us from forming "friendships" with different protection stress relations youngsters. that they'd be leaving once to procure to truly 'understand them'. And "honest"? existence isn't honest, in simple terms go searching the mess that the international is in at present........

Its all evolution and DNA, and the places we are at also affect the air we breath the sun and much more...

I'm from Canada, and we do have universal health care.
- higher taxes
- shortage of doctors and nurses
- medical equipment may be in short supply
- longer waiting periods for treatment, especially in the emergancy room
- we don't have to worry about health insurance, which doesn't always cover everything
- everything is covered, except for plastic surgery and dental
- peace of mind
- the doctor can focus on treating you rather than how you're gonna pay
that's all I can think of right now. Hope it helps!
