Abstract
It is known that every scientific development is accompanied by a social development, in order to adapt to the current reality, and from this perspective, we find that the legislator amends the provisions of the law, as it is a common social phenomenon that is affected and adapts to the prevailing situation of social relations within society, and there is no doubt that the lineage occupies priority in those relations, as long as the most powerful relationships that come from the blood link, and therefore the people of law must highlight more the subject of the genetic footprint, so the legislator is called for the enactment of legal rules that are in line with the size of scientific development to overcome the barriers and traditional rules and their restrictions.
The Algerian legislator of other comparative legislation keeps pace with scientific and technological development, and seeks to modernize the judiciary in relying on modern and more accurate means in the field of proving descent to preserve the child's right to identity by proving his lineage.
