Hair DNA Samples of Aboriginal People Reveals Populations Still Present In Australia Today
A DNA analysis that published in Nature has again confirmed that the hair sample collected from Aboriginal people across the Australia in the early mid-1900s has revealed that the population that arrived 50,000 years ago have been continuously present. The analysis indicated that the populations stayed in specific areas during the continental migration have been present in the same regions ever since.
According to PHYS ORG, the researchers that analyzed the mitochondrial DNA from 111 hair samples that were originally collected across the Australia from 1928 until the 1970s, allows tracing a maternal ancestry. The results show that the modern Aboriginal Australians are the descendants of a population that arrived 50,000 years ago in Australia.
Professor Alan Cooper said that it is fantastic that from the basic population the patterns have persisted for the next 50,000 years, which shows that the communities remained in discrete geographical regions. Moreover, co-author Lesley Williams added the Aboriginal people was played an important major role in developing the right cultural and ethical system for the study.
ABC reported that the DNA analysis was only taken with a consent of the donors or the descendants and the outcomes were discussed in front with the families before it publishes. The researchers hoping that by this project will lead to a rewriting of Australia's history to include the Aboriginal history and what it means to have on their land for 50,000 years.
However, reconstructing a genetic history of Aboriginal Australia is very complex due to some past government policies that imposed population relocation and a child removal that might erase of the physical connection between the groups and geography of Australia today. According to Brian Oldman, the director of the South Australian Museum, the Aboriginal Heritage Project was to able to exist because of its far-reaching records that are collected in the expeditions, which held in trust for all at the South Australian Museum.
