"How did life come about? The answer to this question goes to the very heart of
our existence on planet Earth.
Did life simply arise from chemical reactions among organic compounds in a
primordial soup left after Earth clumped together from space rubble? If so,
where did the organic compounds come from?
Some of the so-called “building blocks of life” may have been surprisingly
common in the early Solar System.
A team of Japanese and American scientists led by Yasuhiro Oba has analysed
samples taken from the asteroid Ryugu in 2018 by the Hayabusa2 mission and
found uracil, one of the five key bases of the RNA and DNA molecules that are
crucial to life as we know it. Their study is published today in Nature
