100,000 Years Ago – (Israel), there is evidence a child survived for several years after suffering blunt-force trauma at the front of the head and dying around age 12. People from the child’s group must have spent years looking after the child as it would have been unable to care for itself and when it died grave objects were left in the child’s burial pit. Those signs of care for a disabled person suggest that the roots of human compassion and altruism are biopsychosocial human characteristics not a result of religion.
