Question
What is evolution? Give an outline of the origin of life and its gradual complexities.
Answer
Evolution is the process by which different species of organisms develop and change over time, through a combination of genetic variation, natural selection, and other mechanisms.
The origin of life on Earth is thought to have occurred around 3.5 to 4 billion years ago, in the oceans or other bodies of water. It is thought to have involved a combination of organic molecules, such as amino acids, that eventually combined to form self-replicating structures or proto-cells.
Over time, these proto-cells became more complex and developed into the first true cells, which were able to carry out metabolic processes and exchange genetic information. Through a process of natural selection, cells with advantageous traits were able to survive and reproduce, leading to the diversification of life forms.
