Aia ka honua uhane i loko o ka nohona kanaka wale nō. He honua uhane anei ko na holoholona? Hōʻike nā hoʻokolohua i nā holoholona kiʻekiʻe, e like me nā primates a me nā cetaceans, he mau hana neural kiʻekiʻe, hiki ke aʻo a hoʻomanaʻo, a loaʻa pū kekahi mau manaʻo o ke aloha a me ka inaina, akā ma hope o nā mea a pau, ʻoi aku ka haʻahaʻa ma mua o ke kanaka a ʻaʻole lawa e hana i kahi honua uhane piha. ʻO ke ao ʻuhane he ʻano hōʻike wale nō ia o ka honua waiwai a me kahi ʻano holomua o ka neʻe ʻana o ke ola. ʻO ka ʻepekema biological a me ka ʻenehana ka ʻōnaehana kumu a me ka ʻenehana hana e aʻo ai i ke ao ola. ʻO ia ka ʻike ʻōnaehana o ke kanaka i ke ao ola. No ka mea, ʻo ka honua ʻuhane ke ʻano holomua o ka neʻe ʻana o ke ola, ʻo nā hoʻokō āpau o ka moʻomeheu ʻuhane e komo i ka manaʻo o ke ola a loiloi ʻia e ka ʻepekema biological.
