Evolution is the process by which all living organisms have developed over time from the earliest life-forms on Earth to the incredible diversity of species that exist today. It is the driving force behind the development of all life on the planet, from single-celled organisms to complex animals and plants. Evolution occurs through a process called natural selection, which is the process by which certain traits become more or less common in a population over time. Natural selection acts on the genetic mutations or variations that occur in a species, and those that are better suited to their environment are more likely to survive and reproduce. Over time, this can lead to changes in the genetic makeup of a species and its populations, leading to the development of new species. For example, in the Galapagos Islands, finches have evolved into many different species, each with its own unique beak shape and size, which allows them to feed on different types of food. This adaptation was the result of natural selection acting on the genetic variations in the finch population. Fun Fact: Evolution is believed to have first begun about 3.8 billion years ago, when the first signs of life appeared on Earth!
