Scientists have determined features of the appearance, possibly belonging to members of an extraterrestrial race. Nearly one billion people on Earth, says an international group of researchers, are representatives of an alien civilization.
The main parameter that is defined by scientists - a negative RH factor. The majority of people a rhesus factor positive. Only billion had negative RH. According to one theory, this modification may be the result of interference in the genome.
The transfusion of human blood with a negative RH is possible only in case when the donor is also RH negative. In this case, the owner of RH negative can donate to everyone.
There are external manifestations of a negative rhesus. Among them are many people with red hair, low body temperature (typically below 36.6 degrees), blue eyes or green. Often these people have a high IQ.
