We know that Darwinian evolution acts on all forms of life, but does evolution act on non-living materials as well? Otto and his team used a system of three different self-replicating molecules, that, ...

Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...

A strand of RNA just 45 nucleotides long can copy its own complementary sequence in frozen conditions that may resemble early Earth, according to a study published in Science in early 2026. The ...

Although the genetic material of most living organisms is DNA, various self-replicating agents rely instead on RNA, including RNA ...
