CONT

L'EPC (copulation hors couple) permet au cardinal (mâle) de transmettre le plus de gènes possible. D'abord, il féconde une femelle et reste auprès d'elle pour l'aider à élever sa progéniture. En même temps, il féconde d'autres femelles pour s'assurer que le plus grand nombre de ses gènes soit transmis.
