The first organisms to appear on Earth were formed from simple organic aggregates. These organisms were called heterotrophs.Which type of energy-releasing process was most likely performed by those first heterotrophs?
|
aerobic respiration
|
|
anaerobic respiration
|
|
photosynthesis
|
|
protein synthesis

Explanation:
Detailed explanation-1: -According to the heterotroph hypothesis, the first forms of life on the Earth probably obtained energy by anaerobic respiration.
Detailed explanation-2: -Photoautotrophs must have evolved before aerobic organisms evolved.
Detailed explanation-3: -Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
Detailed explanation-4: -Which statement best describes the evolution of cells on Earth? Both chemical and organic evolution occurred simultaneously. Chemical evolution occurred first, eventually making organic evolution possible.
