Looking for LUCA, the last universal common ancestor

Around 4 billion years ago there lived a microbe called LUCA: the Last Universal Common Ancestor. There is evidence that it could have lived a somewhat 'alien' lifestyle, hidden away deep underground in iron-sulfur rich hydrothermal vents. Anaerobic and autotrophic, it didn't breathe air and made its own food from the dark, metal-rich environment around it. Its metabolism depended upon hydrogen, carbon dioxide and nitrogen, turning them into organic compounds such as ammonia. Most remarkable…

The Circle of Life Forms: All living things on Earth descended from a single organism called LUCA (last universal common ancestor) and inherited LUCA’s genetic code for basic biological functions, such as translating DNA and creating proteins. Constant genetic mutations shuffled and altered this inheritance and added new genetic material—a process that created the diversity of life we see today. The “tree of life” organizes all organisms based on the extent of shuffling and alteration between th Nature, Last Universal Common Ancestor, Darwin Tree Of Life, Prehistoric Planet, Geologic Time Scale, Genetic Code, Kid Science, The Circle Of Life, Human Genome

Genomic studies consistently show that all life on Earth is related, but our earliest ancestors may not have evolved in the same way we do now.

Looking for the last universal common ancestor of all living organisms

LUCA, the "last universal common ancestor" of all living organisms, lived 4.32–4.52 billion years ago, according to a study from NIOZ biologists Tara Mahendrarajah and senior author Anja Spang, with collaborating partners from Universities in Bristol, Hungary, and Tokyo. Their research is published in Nature Communications.

Last universal common ancestor more complex than previously thought Scientists call it LUCA, the Last Universal Common Ancestor, but they don't know much about this great-grandparent of all living things. Many believe LUCA was little more than a crude assemblage of molecular parts, a chemical soup out of which evolution gradually constructed more complex forms. Some scientists still debate whether it was even a cell. New evidence suggests that LUCA was a sophisticated organism after all, with a Scientists, Nature, Zoology, Ecology, Complex Structure, Living Things, A Cell, Oct 11, Human Behavior
