CBSE Class 12 Biology Chapter 7 – Chapter Description
Evolution can be called the study of the origin and development of life forms on earth. Have you ever questioned how did humans appear on earth? How do different kinds of organisms exist in different habitats, and how was the origin of life? The concept of evolution scientifically gives answers to these questions. Many theories have been proposed regarding the origin of life.
It is said that the first non-cellular forms of life could have originated 3 billion years back. These could be molecules such as RNA, Protein, Polysaccharides, etc. The first organisms could be single-cell organisms that lived in a water medium. These single-cell organisms eventually evolved into larger organisms over millions of years.
In this chapter, you will learn more about evolution. Darwinian ideas of organic evolution by natural selection, other phenomenon such as habitat fragmentation and genetic drift are also discussed. Besides, comparative anatomy, fossils, and comparative biochemistry provide evidence for evolution apart from the stories of the evolution of individual species. Most interestingly, we will also study the evolution of human beings with different stages of development.
