- Evolutionists believe the microbe LUCA was the Last Universal Common Ancestor of all living things.
- Some evolutionists believe they know where LUCA evolved and what LUCA was like.
- Evolutionists disagree about where LUCA evolved and what LUCA was like.
- No scientists have found LUCA.
The microbe LUCA is supposed to have been the Last Universal Common Ancestor of all living things. Using the magic of modern genetics, scientists in 2016 came up with a description of LUCA. This profile describing LUCA’s physiology and habitat, published in Nature Microbiology, generated headlines declaring “Scientists Find LUCA,” “Meet LUCA,” and “Behold LUCA.” And while journalists practically queued up to get LUCA’s autograph, other scientists begged to differ. They believe LUCA evolved in a different setting altogether, one they concocted from chemistry rather than genetics.To read the rest of this biology-intensive article, click on "Where Should We Look for LUCA, Supposed Ancestor of All Life?"
