Several additional amino acids are found in vials from the 1953 Miller-Urey experiment that probed the origin of life: In addition to the classic experiment, reminiscent of Charles Darwin's envisioned "warm little pond", Miller had also performed more experiments which had never been analysed, including one with conditions similar to those of volcanic eruptions. Yet, holding fast to the standard story in the present day has required some smoke and mirrors tactics 80. From his travels on HMS Beagle, Darwin suspected that the environment might naturally manipulate species, causing them to change over time, but he couldn't find a means to explore this effectively in the wild.
