Earliest humans traced back to Botswana
A study which has been condemned for being misleading has suggested that human kind first began in Botswana.
The study traced the maternal DNA of the oldest available focal humans and found that the closest living DNA is present in modern people living in Botswana.
Whilst this is a possible statistical correlation it may also be a false provocation of statistics. The small sample size of just over one thousand samples and the comparison with living humans to identify habitats from 200’000 years ago may not be a true correlation.
The finding is certainly interesting and has sparked the interest of researchers all over the world. Yet the group of researchers who published the paper have been warned not to over state the findings as fact.
Researchers from the Garvan Institute of Medical Research and the University of Sydney, Australia have claimed their research proves that early humans stayed in Botswana for 70’000 years around what was Africa’s largest lake, the now dried up lake bed that forms the Kalahari desert.
The study claims that their evidence proves that humans split into three groups after the lake dried up due to climate change, one group remained and is genetically still visible in the are to date. One group left and headed North East and another headed to the coast on the South West.
This movement however has been challenged as inaccurate my several key institutions.
Since you’re here …
… we have a small favour to ask. More people are reading Al-Sahawat Times than ever but advertising revenues across the global media industry are falling fast. And unlike many news organisations, we haven’t put up a total paywall. We want to keep our journalism as open as we can. So you can see why we need to ask for your help. Al-Sahawat Times’ independent, investigative journalism takes a lot of time, money and hard work to produce. But we do it because we believe truly ethical media and an unbias perspective really matters.
“I appreciate there not being a paywall: it is more democratic for the media to be available for all and not a commodity to be purchased by a few. I’m happy to make a contribution so others with less means still have access to information.”
If everyone who reads our reporting, who likes it, helps fund it, the future of ethical media and the futures of our staff and their families would be much more secure. For as little as £1, you can support Al-Sahawat Times and it only takes a minute. Thank you.
