"Denisovans Survived on Tibetan Plateau until" Topic

…48,000-32,000 Years Ago

"Denisovans are an extinct hominin group initially identified from a genome sequence determined from a fragment of a finger bone found in Denisova Cave in the Altai Mountains in southern Siberia.

Subsequent analyses of the genome have shown that Denisovans diverged from Neanderthals 400,000 years ago and that at least two distinct Denisovan populations mixed with ancestors of present-day Asians.

In 2019, a 160,000-year-old jawbone from Baishiya Karst Cave, a limestone cave at the northeast margin of the Tibetan Plateau, was identified to be of Denisovan origin…"

Last Universal Common Ancestor Lived 4.2 Billion Years Ago: Study

"LUCA is the node on the tree of life from which the fundamental prokaryotic domains (Archaea and Bacteria) diverge.

Modern life evolved from LUCA from various different sources: the same amino acids used to build proteins in all cellular organisms, the shared energy currency (ATP), the presence of cellular machinery like the ribosome and others associated with making proteins from the information stored in DNA, and even the fact that all cellular life uses DNA itself as a way of storing information.

In new research, University of Bristol scientist Edmund Moody and his colleagues compared all the genes in the genomes of living species, counting the mutations that have occurred within their sequences over time since they shared an ancestor in LUCA…"

A branch of humanity that remained undiscovered until early in this century. What the Neanderthals are to Europe, the Denisovans are to Asia.
