Explore LUCA, our last universal common ancestor, and how scientists are researching its origins to understand the evolution of life on Earth and potentially on other planets. Learn about early life forms, genetic codes, and the challenges of fossil interpretation.
Scientists are using ancient DNA to identify 'ghost lineages'—extinct groups that left no fossils but exist in our genomes. This research reveals a complex, 'bushy' model of human evolution and interbreeding.
Scientists have cracked the genetic code behind orange cats! A mutation in the ARHGAP36 gene, located on the X chromosome, determines if a cat will have orange fur and explains why most orange cats are male.
