– Do you believe in it? If yes, then taking up a course on Evolution can satisfy your quest for information about the past well. The term Evolution can be defined as the study of living organisms, the stages of development and also all nitty-gritty’s about the natural history of Earth.
Over decades of successive generations, there has been a drastic change in the nature and characteristics of our biological population. With evolution came diversity. Have you ever wondered about the reasons that led to the diversity of species, organisms and even molecules like DNA? Probably due to some shared DNA sequences or biochemical and morphological crossovers. The only way to get an answer is by studying Ecology .
The theory of evolution was not coined straightaway. It was a scientific argument that was first brought onto the boards by Charles Darwin . He first finalized upon the theory that evolution occurred by means of natural selection. This was again an outcome of observations like:
Offspring produced survive longer. Natural characteristics and traits between individuals vary. This also implies that rates of survival and reproduction vary too. The difference of natural traits in individuals is hereditary. Did you know that all life on Earth is linked by a common factor? Wondering what? Well, our very last ancestor who is believed to have survived at-least 3.85 billion years ago.
Evolution can be described as descent with modification. Studies show that smallest of changes take place at the base level or the genetic level. While natural selection is one mechanism of evolution, there are many more like sexual selection and even genetic drift.
When individuals of one sex are eager to mate with another, there is a share of traits. Maybe this is how a peacock’s tail came into existence. Today, Evolution is a major tenet of modern Biological Science.
As students, you will first develop insight about evolutionary biology, its pattern, processes and causes. Everything from the theory of evolution to the origin of life, origin of animals and the Cambrian explosion, every topic is explained to the students of Evolution. Why just living organisms? Ecology students are entitled to gain knowledge about the environment on a whole.

the theory that evolution occurred through natural selection. This was again the result of observations such as: • The offspring produced survive longer.
