This has been an interesting week for the evolution of two assumed human ancestors.
First, the journal Science suggested that Australopithecus sediba should be tossed out of the human family tree. Then, National Geographic acknowledged that Homo naledi is “only” 200,000 – 300,000 years old, making it far too young to be a direct human ancestor.
Both discoveries were known to be very controversial.
Then, in 2015 Professor Berger and colleagues published a paper on what they claimed to be a new human species. Found in a cave in South Africa, their discovery consisted of 1,500 pieces of teeth and bones that were not dated, and some experts thought they might be too young to fit into our family tree.
One of the estimates put their age at 912,000 years BP (before present).
Now, in an interview published in National geographic, Berger suggested that H. naledi might be a lot younger.
For evolutionists, the curved ape-like fingers, small skull and other primitive features of H. naledi are an enigma. They believe that modern H. sapiens appeared some 200, 000 years ago, leaving practically no time for evolution.
Chris Stringer of the Natural History Museum in London thinks that H. naledi might be “a relic species, retaining many primitive traits from a much earlier time.”
And least one thing is sure: there’s no end in sight for updates to our assumed family trees, and artists will hardly have to fear for their jobs until the day comes when Darwinian evolution will be tossed out as pseudoscience.
