Of the following, which is best supported to suggest where life is believed to have originated on Earth? Select one: a. RNA world hypothesis b. Primordial soup origin hypothesis c. Subsurface origin hypothesis d. Theory of natural selection

b. Primordial soup origin hypothesis

Explanation:

The primordial soup hypothesis is the basis of the origin of life on earth. Life originated in the ocean water as a result of the combination of chemicals from the atmosphere and energy from the sun to make up the amino acids. The amino acids are the building blocks of proteins. The protein was the basis of the development of life forms and their evolution on planet earth. The chemical evolution supposed to occur at least 3.8 billion years ago.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
