Definition
AI-generated

Paleozoic period of early animal diversification—deep backdrop for metazoan gene evolution.

Why it matters in GWAS

Population structure, demographic history, and mating patterns affect allele frequencies, LD, relatedness, and cross-cohort portability—central to GWAS design and interpretation.

Example usage

"Chronological metadata were harmonized using Cambrian Period conventions so samples could be compared on a consistent timeline."
