Human variation in the shape of the birth canal is significant and geographically structured

There will be a relationship between overall canal shape differences and temperature differences.

When correcting for pairwise genetic tests, the inlet was found to be transversally more oval in colder climates (p = 0.001, R-squared = 0. 39).
