Scientists pinpoint all of humanity’s origins from a single group of people in Africa existing more than 200,000 years ago.

Scientists have found out the source of all humanity. According to them all Modern Humans have evolved from a single group of humans present in the continent of Africa.

The group dwelled in Africa more than 200,000 years ago but then dispersed all over the world. The same group migrated to all parts of the world leading to the population of the planet earth.

The question of humanity’s origin had been plaguing scientists for decades. However one series of extraordinary genetic analyses seems to have found the answer. The analysis published on Wednesday in the journal Nature is one of the biggest studies on human evolution.

In the genetic analysis three separate teams of expert genetic scientists surveyed an array of human DNA samples. The samples were collected from a large number of cultures from across the globe.

Some of the samples were collected from groups for the first time. The genomes of 787 people were sequenced and scans by the three teams. The population groups included indigenous populations like Basques, African pygmies, Mayans, Bedouins, Sherpas, Cree Indians etc.

DNA from indigenous populations is particularly important in terms of human history. Since scientists had mostly analyzed DNA from populations based in Europe and China it was of the utmost importance to have data on indigenous populations.

All three teams concluded even all non-African populations of Modern day humans originated from a single population. The originating population of humanity emerged more between 50,000 to 80,000 years ago, but their migration led to global population.

Basically the study provides proof all of humanity can be traced back to a single source. The new results have already add invaluable information to the map of human genomics.
