Solution

The correct option is D A & D
The diverse life forms on Earth that we get to see in today's world is the result of evolution. Life began on earth at least 3.5 to 4 billion years ago, and it has been evolving ever since. The first living things on earth were simple, single celled, then multicellular and then big animals evolved on this earth, all these due to the process of evolution.
Several attempts have been made from time to time to explain the origin of life on earth. There are many different postulates and theories regarding evolution, given by different scientists at different times. Darwin’s theory of evolution by natural selection opened the way for the modern view of the origin of life.
Evolution is gradual changes that take place according to the need of the organism to sustain itself in nature. The basic unit of evolution is population, natural selection acts on individuals but evolution is a broad term considered for the population. Every individual change occurring in an organism is not an evolution, evolution is the cumulative changes in a population over many generations. Variations lead to the adaptation for evolution, and the basic raw material for variation is mutation, which plays a crucial role in evolution.
