Answer: Amino acids.
Explanation:
There were an famous experiment made by two biochemists called Stanley Miller and Harold Urey, in the year of 1953. They made it at the University of Chicago, USA.
In this experiment, Stanley Miller and Harold Urey simulated hypothetical conditions that Earth’s early atmosphere had, in order to test the hypothesis that gases (as the methane, carbon dioxide, ammonia, amonia and water vapor) allowed inorganic chemicals to form organic molecules.
After one week, these scientis found that organic compounds were formed.
Through this experiment the scientists Stanley Miller and Harold Urey obtained that several amino acids were formed (the most abundant was Glycine).
According to their work, they got 13 of the 22 aminoacids that are used to make proteins in living cells.
A fossil is found that shows the organism that produced it had a skeleton and also suggests that the organism may have had hair covering its body. Based on this evidence, it can also be assumed that the organism is a member of the domain
