Final answer:
Morphological (cranial) and genetic evidence, such as mtDNA phylogenies and archaeological findings, support the East Asian origins of Pacific peoples. Molecular genetics and shared ancestry are additional sources of evidence.
Step-by-step explanation:
Morphological (cranial) and genetic evidence can provide insights into the origins of East Asian populations. One piece of evidence comes from the study of mtDNA phylogenies of the Pacific rat, which suggests a connection between Pacific peoples and East Asia. Additionally, archaeological findings in the Turfan area indicate the presence of individuals with traits commonly associated with East Asian origins. Molecular genetics and shared ancestry can also provide further evidence of East Asian origins.
