27 "So God created man in his own image, in the image of God created he him; male and female created he them.28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth,"
It appears that God did the same for the animal kingdom. See Noah and the animals of the Ark.
2 "Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.
3 Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth."
