Which comes first- the chicken or the egg ?
This seems to be like one of those unanswerable questions. If the chicken came first, then didn’t it hatch from an egg? And if the egg came first, wasn’t it laid by a chicken.
If you believe in science and the theory of evolution, eggs, those miniature incubators of life evolved more than 1 billion years ago, in the oceans of the earth. When land animals evolved about 250 million years ago, the eggs had a tough covering to retain moisture on dry land. Now, genetic material does not alter during an animal’s life. It does, however, change in the egg. Therefore, the first bird that evolved into what we would call a chicken, probably in prehistoric times, must have first existed as an embryo inside an egg. So, the egg came first.
However, which came first is not my concern. As you can see from the title of this piece, I am interested in how the chicken comes out of the egg. I mean one way or the other, the egg has to break for the chicken to come out. Now, it is risky for the mother hen to stamp the egg with its feet or break it with its beak. The chicken may be forced to undergo emergency surgery immediately after birth. The chicken itself is too tiny and helpless inside the egg to try and break it from inside. The question is who will break it.
I found my answer in a standard fourth science book. The solution is so neat you want to salute the love and care of God if you believe in one or the practical intelligence of the power that drives us all.
Just before a chick is ready to hatch, a horny growth called the “egg tooth” develops on the top of its beak. The egg tooth is hard enough to cut the shell. The chick turns its body within the egg and chips the shell with the egg tooth until the shell cracks from the inside and finally breaks open at its broadest part. Parent birds just watch in fascination and do not help to break the shell, but they often carry away the pieces of shell when the chick is free. The egg tooth drops off a day or two after the chick hatches! So, you are provided with a built in tool just for the period when you need it most.
By logical extension, this intelligence of the creative force of existence would definitely take care of each one of us and provide us with whatever we need at the right time for our own good. So, maybe the best strategy is to just surrender and relax.
However, the hen does not have any idea about the future of the egg. Whether it will get life or tawe pe fry hoga!
