Respuesta :

Answer:

the study of fossils.

Explanation:

There are many hypotheses about the origin of life on earth. The most scientific answer to the origin of life came from the study of fossils. The evolutionary nature of life is studied by ancient remains of humans and plants which give us an idea to recreate the past. However, the study of fossil is not a simple topic but requires many professionals from different areas to work collectively. The study of single-cell microbes estimates that life on Earth is about 3.5 billion years ago.
