Abstract
RNA world hypothesis is widely accepted still now, as an idea by which the origin of life might be explained. But, there are many weak points in the hypothesis. In contrast, I have proposed a more reasonable [GADV]-protein world hypothesis or GADV hypothesis, suggesting that life originated from the protein world, which was formed by pseudo-replication of [GADV]-proteins. In this communication, I will discuss about the origin of life from the point of view of the GADV hypothesis.

RNA world hypothesis is widely accepted still as an idea by which the origin of life might be explained
At least one new concept is introduced into the GADV hypothesis (Ikehara 2002; Ikehara 2005; Ikehara 2009; Ikehara 2012): the protein 0th-order structure or a specific amino acid composition will yield water-soluble globular proteins with a relatively high probability, even though amino acids are randomly joined
In other words, according to this concept, entirely new proteins could be produced at a high probability in the absence of any genetic function if proteins can be synthesized in the specific amino acid composition
