Video
I found this video and I enjoyed the different images and thought it related to my blog so decided to post it.. It displays some enjoyable images of African tribes and people, just look at them smiling..

I know that my blog talks about the facial structure and in my last two posts it's the only thing I have touched on. But all this got me thinking and wondering about the many differences between cultures. I started thinking about one specific culture difference that has caused so many unnecessary fights and deaths before. Skin colour. Personally I believe that the colour of any ones skin does not affect their personality or the way in which they should be treated but I still wondered why it is that skin colour all over the world is so different? If we all came from the same land originally, Pangaea? Again I did some research and an idea began to grow. According to scientific research the earliest evidence of human activity traces back to Africa. Taking this into account how did the change in skin tone occur? It is believed that the paler skin types seen in regions such as Northern Europe were caused by a "mutation" in order to help the body absorb more sun light in the colder less sunny regions.
So the other day I was sitting on the bus when I saw an African girl looking at her hands. It was here that I noticed the pale colour of her palms, I wondered why? And then I remembered reading about the change in colour of skin to absorb sun light, it made sense that her palms were pale when I remembered that the best way to absorb sunlight into the body is by the palms of your hand as the skin is sensitive. So this would help to absorb sunlight. So maybe we the paler skin tone is a change in evolution to help humans absorb more sunlight in colder regions after living in the hotter regions such as Africa.

This just a quick post to give credit to any of the websites that have helped me to develop the ideas behind my blog posts.

Asia
Yet again, why the structure?
Today I will be looking into the structure of the continent Asia.
The majority would describe some of their key features to do with the nose and the eyes. After doing some research I found a few theories that seem to make sense. Many places in Asia deal with a harsh climate, snow or desserts, of course there are places on the continent Asia that are not like this but I am speaking of a majority.
In a previous post I spoke about the facial structure on the continent of Africa. I believe that these two can be linked together. I spoke about how wider nostrils would help in an area of higher altitude to breathe in more air when there are lower levels of oxygen, many places in Asia have a high altitude for example in Tibet and a similar nose structure can be seen between the two cultures.

There are reasons to believe that evolution has caused the change in facial structure as snow reflects more light then your average environment, due to this the human body would have to find some way to protect itself against stronger light and this could cause a change in facial structure to the eyes. This would be the same in areas with desserts as more light is also reflected here. The temperatures should come into consideration too, when more of the eye is revealed the chance of dust or cold air etc. has of blowing into ones eye and causing damage is raised. The desserts and harsh weather conditions in some places in Asia could affect the facial structure of the eyes.

Why the structure?
After doing some research I found some theories that spoke about the facial structure of Africans. I don't want to categorise a whole culture into one group but if I were to explore into different countries and tribes I could be here awhile as each is unique and slightly different. For this reason I am going to do a general summary of a theory. Africans from different parts of Africa vary in facial structure. But I am just going to cover the majority. It is a stereo type to say that all Africans have a wide nose and big lips however this is not true.
Some of the theories I have read believe that African natives have a wider nose to breathe more air in areas of lower oxygen levels. I think that this makes sense because Africa has a high altitude especially in places such as South Africa, however surely this would mean that African people should have a larger lung capacity verses another culture? We can see a similar structure in the noses of many Indian and Chinese people all which are warmer areas. I once went to the doctor and I spoke to him about why on cold days when you breathe out your mouth water vapour appears yet on the same cold day breathing out your nose does not have the same affect. We then spoke about how there is a part in your nose that heats the air when you breathe it in so on a cold day it is better to breathe through your nose as your mouth does not do this. This all got me thinking.
Why is it that majority of Caucasians have a thinner nose than other cultures? Going back a few years when the majority of Caucasians lived in places in Northern Europe (a much colder region) it begins to make sense. If nostrils on a human being are smaller the easier the air is to heat, such as in colder regions like Northern Europe how ever in hotter regions such as Africa and China nostrils can be wider because heating the air before intake into lungs is not as important and as altitude is higher more air may be needed to get a higher level of oxygen with each breath. So this may explain the difference in facial structure between noses in different cultures.
as an example I have used the great Nelson Mandela of South Africa.

Before I start I would like to say that I have no intentions to discriminate or insult any cultures I am just curious about human evolution and the reasons behind them. I am not here to say that any culture appearance is wrong or that another is better. I would like to say that although I have done research into my work I am not scientifically right I would just like to put out a few theories and ideas, feel free to comment with any of your own theories. I would like to find out why facial structure all over the world is different with theories such as Pangaea (that all continents were connected and the world was one piece of land) then surely humans should all be similar in facial structure not radically different?

What it's about:
If you have ever wondered why the facial structures of cultures of the world are so different then this blog may be of interest to you. I am going to be researching and posting on the factors and reasons for different facial structures.
