The potential mother would be wasting her body's energy and resources constantly producing milk without using it to feed her baby, requiring for her to attain more energy, where she could have just waited until she actually gets pregnant and then start producing milk for her baby once it is close to being or already born.
Answer: The benefit of evolutionary benefit of milk production regulation mechanism is that the mother will not waste her energy or nutrients required for her growth and development to produce milk at that time rather it will be during her late pregnancy stage where the mammary gland will be activated by oxytocin hormone to produce milk automatically to breast feed infants at birth.
Explanation:
Evolution of lactation or mammary glands in mammals has been very important to feed the infants.
Lactation refers to production of milk from the mammary glands. Lactation normally occur at post pregnancy stage. At this stage the infants are born and milk is been secreted by the mammary glands to breast feed the young ones. Lactation doesn't occur all the time but it occur during late to post pregnancy stage. This is activated by oxytocin which help to implant embryo in the uterus and help in lactation.
