These bizarre microbes are revealing the origins of complex life

Scientists are getting their hands on Asgard archaea - these mysterious single-celled organisms that were discovered in 2015 and completely changed how we think about evolution. So here's the thing: these microbes appear to be the ancestral ancestors of all eukaryotes, meaning complex life like plants, animals, and fungi actually branch off from archaea, not the other way around. Researchers have spent years coaxing these finicky, slow-growing cells into stable cultures - a task so painstaking that one scientist drove 2,500 kilometres across America with a precious sample in her mother's SUV. Now that they can finally study Asgard archaea directly under microscopes, they're discovering surprising shapes and behaviours that are revealing what made the leap to complex life possible.
