Final answer:
It is necessary to know the sex and ancestral route of a sample before estimating stature, as these factors affect the stature estimation process and improve accuracy in forensic and bioarcheological applications.
Step-by-step explanation:
False: It is indeed necessary to know the sex and ancestral route of the sample before estimating stature. In forensic anthropology and bioarcheology, when estimating stature from skeletal remains, the sex and ancestry of the individual play crucial roles. These factors influence the regression formulas and mathematical models used since stature estimation is based on the proportions and lengths of certain bones which have been shown to exhibit variations due to sex and ancestral background. This information can drastically improve the accuracy of stature estimates, which is fundamental in forensic casework and research related to past populations.
