The so-called "instinct" given to female animals is amazing. I would rather call it a God-given talent or skill. It is present throughout life forms that have male and female partners. Evolution has no explanation for this nor the development of male and female life forms. It is God given. God said to Noah:
18 "But with thee will I establish my covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons' wives with thee.
19 And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female.
20 Of fowls after their kind, and of cattle after their kind, of every creeping thing of the earth after his kind, two of every sort shall come unto thee, to keep them alive.
21 And take thou unto thee of all food that is eaten, and thou shalt gather it to thee; and it shall be for food for thee, and for them.
22 Thus did Noah; according to all that God commanded him, so did he."
Can this maternal skill be distorted-of course because we live in a corrupt earth, but it was not God's original plan.
