Scientists have identified the last universal common ancestor (LUCA) of all life on Earth, dating it to around 4.2 billion years ago. LUCA was a complex, cellular organism that thrived in hot, oxygen-free environments using hydrogen-based metabolism and had early immune systems, indicating rapid evolution of life shortly after Earth's formation.

New research pushes back the timeline of LUCA, the last universal common ancestor, to about 4.2 billion years ago during Earth's Hadean Eon, suggesting life was active and evolving in extreme conditions much earlier than previously thought, with signs of primitive immune systems and environmental interaction.

A new study suggests that the Last Universal Common Ancestor (LUCA) of all life on Earth existed around 4.2 billion years ago, much earlier than previously thought, and likely had an early immune system, indicating that life was fighting off viruses from its very beginnings.

Scientists are revising their understanding of the emergence of genes and amino acids in early life, suggesting that the traditional model may underestimate the role of certain amino acids like tryptophan and the complexity of early genetic codes, which could have implications for searching for life on other planets like Saturn's moon Enceladus.

Scientists are reevaluating the order in which amino acids emerged in the origin of life, suggesting that early protolife may have included a broader range of amino acids than previously thought, which could reshape our understanding of life's beginnings on Earth and potentially elsewhere in the universe.

Recent evidence suggests that life on Earth emerged much faster than previously thought, possibly within a few million years of the planet's formation, challenging the long-held view of a hellish, uninhabitable early Earth and emphasizing the need for open-minded research into the origins of life.

A study led by Sawsan Wehbi at the University of Arizona suggests that the traditional understanding of genetic code evolution is flawed. The research indicates that early life forms preferred smaller amino acids and those binding to metals, with sulfuric amino acids joining later. This challenges the consensus based on the Urey-Miller experiment and suggests that the genetic code evolved through stages, with earlier codes now extinct. The findings have implications for astrobiology, particularly in sulfur-rich environments like Mars and Europa.

A University of Bristol-led study has pinpointed the existence of LUCA (Last Universal Common Ancestor) to about 4.2 billion years ago, revealing it as a complex organism with an early immune system. Through genetic analysis and evolutionary modeling, researchers found that LUCA played a crucial role in early Earth's ecosystems and was already engaged in an arms race with viruses. The study highlights LUCA's complexity and its environmental impact, suggesting that life may flourish on Earth-like biospheres elsewhere in the universe.

New research suggests that life on Earth may have begun as early as 4.2 billion years ago, with the Last Universal Common Ancestor (LUCA) emerging shortly after the planet's formation. This complex organism, which had an early immune system, is considered the root of all modern cellular life. The study, published in Nature Ecology & Evolution, used genetic and fossil data to trace LUCA's existence and its role in Earth's early ecosystem.

The Holdovers, a film written by David Hemingson and nominated for best original screenplay at the Oscars, is facing accusations of plagiarism from writer Simon Stephenson, known for Luca and Paddington 2. Stephenson claims that The Holdovers bears striking similarities to his unproduced screenplay Frisco, which landed on the Black List in 2013. He has prepared documents comparing scenes and structure, alleging that the entirety of The Holdovers has been copied from Frisco. Representatives for the writers and the WGA have been contacted for comment.

Pixar's films Soul, Luca, and Turning Red, which were originally released on Disney+ due to the pandemic, will now have theatrical releases. Soul will be released on January 12, followed by Turning Red on February 9, and Luca on March 22. The decision to release these films in theaters was influenced by a slowdown in family product next year and the opportunity to promote the upcoming release of Inside Out 2.
