Thank you for your reply. I listened to a book not long ago by a womanQuote
The find at the Qesem Cave in Israel are changing everything, from the swan wing bone showing that the inhabitants were perhaps practising swan shamanism 420,000 years ago, to the discovery there of teeth from the same age that are essentially the same as ours. Who were these Qesem individuals? Were they our precursors or were they linked in some manner with the Denisovans who were like us physiologically and may well have closer links to our ancestors than has previously been thought.
who has become an expert in micro-analysis of traces of food left on teeth, and the analysis of bones which leads to an understanding of their diets.
Is there an objective opinion that the Denisovans were in fact that third branch of humans you mention?
