Our ancestor’s ‘leaky’ membrane answers big questions in biology

12 agosto 2014

All life on Earth came from one common ancestor –- a single-celled organism -– but what it looked like, how it lived and how it evolved into today’s modern cells is a four billion year old mystery being solved by researchers at using mathematical modelling. Findings suggest for the first time that life’s Last Universal Common Ancestor (LUCA) had a ‘leaky’ membrane, which helps scientists answer two of biology’s biggest questions.
