Earliest, every so much more steady connection species lacked one department off labor, casting doubt towards the division from work idea. This new Embers performed submit an alternate idea and that did predict male-female connection really. This was from inside the way to the next matter: Is a separate mother provide by herself along with her child at the way more-or-less the same time frame? In case the response is zero, up coming men-feminine bonding was forecast; if for example the answer is actually sure, then feminine-men connection is unrealistic. It idea may establish why most bird kinds have bonding.
