it's all in the DNA and the timing of fertilization and with who you mate. but really, DNA has so much genetic information that has passed down from generations that the traits are endless. the reason why we may see more ppl with brown eyes and brown hair is because they are dominant traits. but still, it's cool how different and unique these same exact traits come out in each person.

It all begins at the tower of babel where God confused the language of the people because they wouldn't spread out and populate the Earth like he commanded them too. After that the people grouped together with people of the same language. The people couldn't live together anymore because they couldn't understand what they were saying. To solve this problem they traveled to different parts of the world and settled down there. Over a period of time the different groups intermarried and had more children and the developed unique traits. Take the Japanese for example, They have a unique eye shape. over the years of marrying and intermarrying a gene for that eye shape got passed around and eventually affected all of the population there. I hope that this helps you and I am sure that other people can build on what I said and add more detail if you are still not understanding.

The differences aren't that great. Wherever in the world you go, you you can identify people as separate from any other life form.
