Survival of the fittest

Introduction
Hi, I am Nikhil of grade 9. I love to read Agatha Christie mysteries. I enjoy sciences too.

“Survival of the fittest” is a phrase that was first used by the biologist and philosopher Herbert Spencer, and is said to have originated from the evolutionary theory that Charles Darwin has proposed. It was used in reference to the natural selection, a mechanism through which beings capable of reproducing choose their mates, unlike artificial selection- which involves the process of selective breeding.

An Apple's Journey
by Arnim Kucchal - Grade 3B Madhapur

Hi! I am an apple. Right now, a little girl is picking me up and putting me in her mouth and all her teeth are munching me and I am getting mashed into tiny bits. Now I am traveling through the esophagus. Whew! What a long journey! Let's move on now. I’m in the stomach. I am getting churned with all the gastric juices. Now I am going through a small tube. Now what is that called again? Oh yes, the small intestine. More juices from the liver and pancreas in here. I can feel all the nutrients are getting absorbed from me. Oh god, this journey is even longer! Moving on to the next part, I am in the large intestine. All the water is getting absorbed from me. Now I am in the rectum. I guess I am going to be here for a while. Soon I 'll be going out of the anus in the form of a semi-solid waste.
