The media have been talking about “genetically modified humans” and “designer babies.” But what they’re really talking about is germ-line engineering: a process that could help eliminate heritable diseases. So why do some scientists want to pause the research?
What are the origins of life? How did things go from non-living to living? From something that could not reproduce to something that could? Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in one form or another.
