Did we look different from each other, right from the past..?? Today by just looking at faces we can differentiate if the person belongs to China, India, Russia etc.. But what if I say, we all look same in the past.. Yeah its true, there were no countries, no religion, no discrimination, no hate.. We used to live with each other happily like a family.. Wanna know lets travel back 3 lakh years before..
We all used to live in Africa at that time. The environment was warm and naturally rich. We all looked same. Our only objective was ‘survival’. As one couldn’t able to survive alone, we used to live and hunt in groups and stay at one place. Earth was actually the heaven at that time as there were no racism. And yeah, our ancestors prefer grass bedding to create comfortable areas for sleeping and working on, at least 2 lakh years ago.
These beds consisting of sheaves of grass of the broad-leafed Panicoideae subfamily were placed near the back of the cave on ash layers. The layers of ash was used to protect our ancestors against crawling insects while sleeping. Our ancestors also used hot springs as a cooking resource to boil fresh kills, long before humans are thought to have used fire as a controlled source for cooking.
But around 1.3 lakh years before, an interglacial period changed everything. Climate of the earth started increasing rapidly and this started melting icy routes which goes out of Africa. So, some of our ancestors decided to migrate to other countries, while others decided to stay in Africa. Our migrating ancestors took only required food with them, while shared remaining with others. This act of kindness we call today, ‘Law of Sharing’.
Out of Africa, our ancestors went to levantine regions first and started spreading to Syria, Lebanon, Jordan, Israel, Palestine and Turkey.. And just after 1000 years, some of them migrated towards europe and asia. And for 40000 years, our ancestors had spread to India and China. And that’s how 4 human raeces born.
Do you know, that 4 human races? They are white/Caucasian, Mongoloid/Asian, Negroid/Black, and Australoid. According to darwin theory of evolution, Indians are the mixture of Caucasian, australiazoid and mongoloid. North India people have more caucasoin genes, South India have more Australiazoid genes. While, North East have mongoloid genes..
But what about china? Well friends, they all belongs to mongolian races. But the question is, why they have small eyes and flat faces. Friends, its not because god created them like this, that was the gift given to them by evolution through natural selection. Yeah friends, when they came to siberia from africa. It was necessary to protect eyes from snow blindness and natural selection given them low exposure eyes i.e. squinty eyes, to protect them against it..
But what about their flat facial features? You know well about the siberia’s extreme cold temperatures. In order to survive such extreme cold temperatures it is necessary to prevent heat loss. So, natural selection bought changes in their facial features and had given them extra face fat. It also helped them to eat icy-meats. Epicanthel fold is also believed to have evolved in them in order to provide defense from the extreme cold and extreme light that occur in Eurasian arctic and northern regions.
But what about Europeans? How they got their pale colour? Ancestors who were migrated to northern latitudes often don’t get enough UV to synthesize vitamin D in their skin so natural selection has favored two genetic solutions to that problem—evolving pale skin that absorbs UV more efficiently or favoring lactose tolerance to be able to digest the sugars and vitamin D naturally found in milk. That’s why we look different from each other. Share it as much as you can and make people aware of truth.. Because knowledge can only save this beautiful world from ‘destruction’ which may cause from ‘discrimination’..
