# behav: more about homebodies vs natural explorers

<< Some species of roundworms are just one millimeter long. Their brains have only 302 neurons, compared to our own 86 billion, and lack any recognizable breathing system. They share only 35 percent of their DNA with human beings >>

<< But we have more in common with these creatures, known to scientists by their Latin name Caenorhabditis elegans (C. elegans), than one might think. Hidden in that 35 percent are clues to the origins of our behavior >> Andres Bendesky.

<< Like some humans, some C. elegans are homebodies [..] But other C. elegans are natural explorers >>
