Nebula-Relay Hypothesis: Primitive Life in Nebula and Origin of Life on Earth [PDF]
Acta Astronomica Sinica,2021,62(3):28, 2019 A modified version of panspermia theory, named Nebula-Relay hypothesis or local panspermia, is introduced to explain the origin of life on Earth. Primitive life, acting as the seeds of life on Earth, originated at pre-solar epoch through physicochemical processes and then filled in the pre-solar nebula after the death of pre-solar star.

Homochirality: a prerequisite or consequence of life? [PDF]
Prebiotic Chemistry and the Origin of Life, edited by Neubeck,
Anna; McMahon, Sean. ISBN: 978-3-030-81039-9. Cham: Springer International
Publishing, 2021, pp. 87-115, 2020 Many of the building blocks of life such as amino acids and nucleotides are chiral, i.e., different from their mirror image. Contemporary life selects and synthesizes only one of two possible handednesses. In an abiotic environment, however, there are usually equally many left- and right-handed molecules.
