May 15, 2022 · To account for the origin of life on our earth requires solving several problems: How the organic molecules that define life, e.g. amino acids, nucleotides, were created. How these were assembled into macromolecules, e.g. proteins and nucleic acids, - a process requiring catalysts.
Consideration of the origins of life necessarily branches into questions of biology, chemistry, paleontology, geology, planetology, and astronomy, and perhaps now we could add questions of systems science and complexity and information theory.

University of Massachusetts and Goddard Center for Astrobiology Astrobiology, also known as bioastronomy or exobiology, is the study of the origin, evolu-tion and distribution of life in the Universe. These are subjects which have been of interest to mankind throughout recorded history. Although questions of origins have most fre-quently invoked di...
This book aims at exploring several crucial issues related to the origin(s) and evolution of life in the Universe, starting from the only example of life known so far: terrestrial life. It is clear, though, that many of the circumstances that surrounded the emergence of life on Earth may have occurred, are occurring or will occur in other regions o...
tion origin-of-life researchers must explain “the origin of.” What follows will first seek to characterize the information in DNA, RNA, and proteins as an explanandum (a fact in need of explanation) and, second, to evaluate the efficacy of competing classes of explanation for the origin of biological in-formation (that is, the ...
Chapter 13 RNA & the Origin of Life 2 life arose from an RNA World. Of course, we cannot go back in time and see if life evolved from RNA molecules, and there is no fossil record (with one possible exception as we will come to) that we can interrogate. What we might be able to do, however, is re-create in a test tube life or at least aspects
