Man-made chemicals evolve into life-like ecosystem

(…) Joyce and his graduate student Tracey Lincoln, added the enzymes into a soup of building blocks, strings of nucleic bases that can be assembled into RNA, DNA or larger strings, and tweaked them to find pairs of enzymes that would reproduce. One day, some of the enzymes “went critical” and produced more RNA enzymes than the researchers had put in.

It was an important day, but Joyce and Lincoln wanted more. They wanted to create an entire population of enzymes that could replicate, compete and evolve, which is exactly what they did.

Ghosts & Darwin

According to a recent survey, Americans think the existence of ghosts is as probable as Darwin’s theory of evolution:

  • Slightly more people – but both are minorities – believe in Darwin’s theory of evolution (47%) than in creationism (40%).
  • Sizeable minorities believe in ghosts (44%), UFOs (36%), witches (31%), astrology (31%), and reincarnation (24%).

I wonder what these numbers look like for my ultra-liberal corner of Europe.
