and living organisms have been interacting with their environment for billions of years. We recognize that life-forms have evolved to adapt to the environment on Earth, and
A discussion of the possibility that there may be life on Mars that originated on Earth and the alternative possibility that life on Earth originated on Mars. © Open University (A Britannica Publishing Partner) Examine the speculation of the presence on Mars of life that originated on Earth ...
This has revived interest in the prospect that terrestrial life originated in an extraterrestrial environment. The idea that life on Earth has an extraterrestrial origin is not controversial. Carbon, nitrogen, oxygen, sulfur, and phosphorus, the chemical elements on which life is based, formed ...

By studying the RNA sequences of ribosomes — the cellular machines that make proteins — Woese was able to show that Charles Darwin was cor-rect in suggesting that all life arose from a single, now-extinct, common ancestor.It remains unclear how and when life first originated on Earth, bu...
Either life broke the symmetry of the environment it originated in or the environment already contained (some degree of) an enantiomeric excess (Patty et al., 2018). That life was intrinsically homochiral very early on is supported by the observation that the formation of RNA, a crucial ...
