Yes, natural selection causes evolution, which results in the variety of life on earth.
no
No, all life evolves. Bacteria evolve, viruses evolve, protists evolve, plants evolve, fungi evolve and animals evolve. Evolution is driven by Natural Selection. So, no. The evolution of all life on Earth is driven by Natural Selection: all bacteria, plants, animals, mammals, fish, insects, biochemical pathways, behaviours et cetera evolve by Natural Selection.
Biodiversity emerges from genetic diversity within species, species diversity, and ecosystem diversity. These three components work together to create the variety of life forms and ecosystems on Earth.
Living things are found on Earth due to a combination of factors, including the presence of liquid water, suitable temperatures, and a variety of chemical elements necessary for life. The Earth's atmosphere also provides protection from harmful radiation, making it an ideal environment for life to thrive. The diversity of life on Earth has evolved over billions of years through processes such as natural selection and genetic mutations.
Natural selection is a key mechanism for evolution by which favorable traits are passed on to future generations, leading to the diversity of life. However, other factors like genetic drift, mutation, and gene flow also play a role in shaping the origin and diversity of life on Earth. Therefore, while natural selection is an important explanation, it is not the sole factor in the evolution of life.
Natural Selection
Scientists explain the great diversity of life on Earth through the process of evolution by natural selection. Over millions of years, organisms have evolved and adapted to different environments, leading to the wide variety of species we see today. Environmental factors, genetic variation, and natural selection all play a role in shaping the diversity of life on Earth.

The Earth was populated with diverse species and life forms through a process called evolution. Over millions of years, organisms adapted to their environments, leading to the development of a wide variety of species with different characteristics and traits. This process of natural selection and genetic variation has resulted in the rich biodiversity we see on Earth today.
Biodiversity refers to the variety of living things on Earth which help maintain a natural balance within ecosystems. It includes all the different species of plants, animals, and microorganisms that contribute to the functioning of the environment.
Darwin made bold assumptions about heritable variation, the age of Earth, and relationships among organisms. First, in order for beak size and shape to evolve, there must be enough heritable variation in those traits to provide raw material for natural selection. Second, differences in beak size and shape must produce differences in fitness that cause natural selection to occur.

Scientists believe in natural selection because it is a well-supported and extensively studied mechanism that explains how species evolve and adapt to their environment over time. The evidence for natural selection comes from various fields of study, including genetics, paleontology, and ecology, providing a strong foundation for understanding the diversity of life on Earth. Additionally, the observations of natural selection in action, such as antibiotic resistance in bacteria or beak size in finches, further support its validity as a key driver of evolution.
