Could there be a connection between a squashed million-year-old skull and the Denisovans? I look at whether a provocative new study can be squared with what we already know from ancient genomes. I think there's a way.

Million-Year-Old Skull Reveals Homo Sapiens Are Nearly Twice As Old As We Thought
This article examines the split between Neanderthals, Denisovans, @ Homo sapiens, evaluating when this split took place and the ancestor-descendent relationships between each group.

Chimps and other species resort to eating bat guano to meet nutrient and mineral needs as their ecosystems are altered by human activities, depleting resources.

Some small primates still do this - dwarf lemurs in Madagascar dig themselves underground and sleep for several months when it gets too cold, protecting themselves from freezing temperatures under layers of roots and leaves.

The earliest members of primate evolution, existing in the Paleocene epoch, most likely lived in North America in a cold climate with hot summers and freezing winters, according to this research.
This trait helps primates navigate an unpredictable social world, and likely provided key foundations for the evolution of human culture and sociality as they extended across time, space, and group boundaries
