Life on Earth began with the simplest forms of life known as protocells, which lacked complex structures but gradually evolved into more advanced organisms.
Over millions of years, these early life forms gave rise to multicellular animals, with the first examples being simple creatures like Dickinsonia.
Over time, increasingly complex systems such as bilateral symmetry, nervous systems, and eyespots developed, leading to the first vertebrates. Fish emerged as the first vertebrates, followed by the transition from sea to land with the evolution of tetrapods, which ultimately led to amphibians, reptiles, and mammals.
Around 200 million years ago, mammals evolved, with small, shrew-like creatures emerging alongside the dinosaurs.
Over time, mammals developed traits like hair, mammary glands, and more efficient circulatory systems. Fast forward to 7 million years ago, and the first great apes appeared, leading to the rise of early humans in the genus Homo. These early humans were marked by significant advancements, such as bipedalism, larger brains, and the development of tools, language, and fire.
Today, human evolution continues to evolve in the context of technological advancements, potentially leading to a future where genetic diversity decreases and the human species adapts to the changing global environment.
