Evolution of Earth

The Earth's evolution spans billions of years. It began as a hot, molten planet, gradually cooling and forming a solid crust. Life emerged around 3.5 billion years ago, evolving from simple to complex forms. Over time, continents shifted, climates changed, and diverse species evolved. Mass extinctions also played a role, leading to the rise of new life forms. Eventually, mammals emerged, and primates evolved into humans. Human civilization developed over the past few thousand years, shaping the world's landscapes and ecosystems.
