Evolution is a complex process of change over time. Natural selection is a key concept in evolutionary biology - it can be summarised as the selection process favouring traits that have led to greater numbers of organisms. Class 12 Biology Evolution proposes to teach about the most important subjects related to Evolution, such as population growth and variation, gene linkage, sexual reproduction and genetic drift. We will also explore the importance of natural selection when trying to understand Evolution. In Evolution NCERT Class 12, we will touch on kinetics and ecosystems. The goal is for students to leave with a complete understanding of how Evolution works and an appreciation for biological diversity. Evolution is a phenomenon occurring on Earth for billions of years. The animal kingdom has constantly been changing and adapting to new environments. As a result, Evolution is distinctly heterogeneous, depending on what species is evolving. For example, the Evolution of sharks might be different from the Evolution of chimpanzees because sharks are animals in which it's hard for any changes to occur, while chimpanzees are animals, and it is relatively easy for changes to occur. Class 12 Biology Evolution highlights different aspects of Evolution, and it includes learning about the process of natural selection, convergent Evolution, divergent Evolution, extinction, and much more. Evolution NCERT Class 12 talks about the process of natural selection and how it occurs.
Every time you meet someone, they will be different from the last time – this is what evolution is all about. The process of change over a long period is due to random and gradual genetic variation. However, evolution in living organisms goes to different stages that pass through generations depending on experience & environment.
Evolution is not limited to one species, though, as it can happen in multiple forms, such as microbes and even physical structures like coral reefs. Depending on the situation and need of the species, it can help their survival. The need for survival is pivotal to evolution, where adapting to different environments becomes necessary. The process of evolution is complex, and its effects are also interconnected with many other organisms worldwide.
Thus, genetics and evolution is the study of the branch of biology that explains the evolution of life and diversity on planet earth. Charles Darwin is considered to be the pioneer in the study of Evolution as this word was first mentioned in his book in 1859, which also described in detail the process of “Survival of the fittest”.
