EXTRATERRESTRIAL EVIDENCE 



The study of meteorites — stimulated by the fall of one big 

 unusual carbonaceous meteorite on Murchison, Australia, in 1969 - 

 has allowed close examination of extraterrestrial material. Numerous 

 laboratories have shown that the Murchison meteorite contains 

 many organic compounds that appear to have been synthesized 

 extraterrestrially by nonbiological processes. One of the first classes 

 of compounds studied was the amino acids. As compared to the 

 20 amino acids found in proteins, a much larger number (over 100) 

 have been estimated to be present in carbonaceous chondrites.
