Because the molecular evidence is so strong, it has been accepted when used by expert witnesses when testifying in court.
The legal test in the U. S. for admissibility of expert testimony is the Daubert guidelines
The Daubert guidelines state that a trial court should consider five factors in determining "whether the testimony's underlying reasoning or methodology is scientifically valid":
(1) whether the theory or technique in question <hl>can be and has been tested</hl>;
(2) whether it has been <hl>subjected to peer review and publication</hl>;
(3) its known or potential error rate;
(4) the existence and maintenance of standards controlling its operation; and
(5) whether it has attracted widespread acceptance within the relevant scientific community
(quoted nearly verbatim).
Phylogenetic analysis has officially met these legal requirements.
In the past decade, phylogenetic analyses have played a significant role
in successful convictions in 9 court cased documented in the article below.
Phylogenetics: "the study of evolutionary relatedness among various groups of organisms (for example, species or populations), which is discovered through molecular sequencing data and morphological data matrices".
