Plants have their own strategy for development. For example, we shall consider a single germ cell growing into a huge tree without depending upon the mother tree. We can also think about a beautiful flower blooming from a small bud, which later becomes a fruit and ripens fit to be consumed. We are now persuaded by this example that an organism develops under our eyes at a programmed period of time.
Talking about animals, they too have natural plans for their evolution and development. Let us now regard the development of a chick from the hen’s egg. The mother hen lays eggs in a sheltered and secure place. It makes sure to provide safety and warmth for the eggs by sitting on them and watching it. The embryo inside is only the miracle worker, which develops slowly under the mother’s warmth. The love and care of the mother hen for three full weeks enables the eggs to hatch. Out comes the tiny chick with already fully developed legs walk and bright little eyes to look around.
Yet the motherly duty of the hen is not entirely over. She protects her chicks under her wing and teaches them other survival activities. Here, we can see that the mother’s job was only to lay the eggs and help the eggs to hatch. But she cannot claim that she has made the legs or eyes or the softness of the skin which were formed inside the eggshell
