Biologists have always been intrigued by origins of man. That is why they have taken many approaches to explaining the still unanswered questions. Recently, a new study conducted by a team of biologists has led to more conclusive results. This was based on the analysis of the sequences of the human genome.
Indeed, thanks to these studies rooted in human DNA, scientists have been able to develop a family tree immense, precise and complete. To achieve this, they used diagrams combining ancient and modern human genomes.
The most accurate graphical representation of evolution?
The research was notably carried out by the Dr Yan Wong, an evolutionary geneticist at the Big Data Institute at the University of Oxford. The investigations were carried out in this same establishment.
The researchers’ approach resulted in what would appear to be the most representative tree of human evolution. They were able to provide more details concerning the methods leading to the familiarization of genetic information of an individual with other people.
“This is a family tree for all of humanity that models as accurately as possible the history that generated all the genetic variations that we find in humans today. »

To achieve this, biologists have combined many tree sequences common individual, as well as 8 data structures distinct. Thanks to this experiment, these scientists noticed that the old genes included other very old extracts. They were even able to calculate the distribution temporal recent common ancestry on several volunteers.
Very few assumptions for maximum precision
In order to summarize the main characteristics of human history, these experts then integrated certain geolocation data on all the genome specimens. Of course, this approach has highlighted important aspects of the history of human evolution, including in particular the movements outside Africa.
“The beauty of our approach is that it makes very few assumptions about the underlying data and can also include modern and ancient DNA samples. »
