Why Do Predators Ignore Sleeping Humans?

Dogs did not choose humans; rather, wolves made the first choice to approach human camps approximately 15,000-40,000 years ago, seeking food scraps and waste. Wolves that were less fearful of humans had survival advantages, leading to natural selection for tameness. Unlike other domesticated animals like sheep and cattle, which were domesticated through force and confinement, dogs may have domesticated themselves by choosing proximity to humans. This process, demonstrated by Dmitri Belyaev's fox experiment, triggered domestication syndrome, including physical changes like floppy ears and curly tails. Over generations, dogs developed the remarkable ability to read human communication, including following human gaze and interpreting facial expressions. This evolved into a mutual oxytocin feedback loop, where eye contact between dogs and humans releases the bonding hormone in both species, creating a genuine emotional connection. The dogs that bonded most deeply with humans were kept and fed, while those that didn't were abandoned or killed, making the human relationship a survival advantage for 15,000 years.
