 - 1. Evolution is the process by which species of organisms change over time through the gradual accumulation of small genetic modifications. This process results in the development of new species that are better adapted to their environments. Evolution is driven by factors such as natural selection, genetic drift, and mutation, shaping the diversity of life on Earth. Charles Darwin's theory of evolution by natural selection is a central tenet in the field of biology, providing a framework to understand the complexities of life's development and diversity.
