In a new study, published in Nature this week, an international research group led from Uppsala University in Sweden presents the discovery of a group of microbes that provide new insights as to how complex cellular life emerged.
The study provides new details of how, billions of years ago, complex cell types that comprise plants, fungi, but also animals and humans, gradually evolved from simpler microbial ancestors.
Life on our planet can be divided into three major groups. Two of these groups are represented by tiny microbes, the Bacteria and the Archaea. The third group of organisms comprises all visible life, such as humans, animals, and fungi – collectively known as eukaryotes.
Whereas the cells of bacteria and archaea are generally small and simple, eukaryotes are made up of large and complex cell types.
The origin of these complex cell types has long been a mystery to the scientific community, but now an international collective of researchers led by Uppsala University has identified a group of microorganisms that provides a unique insight into the evolutionary transition from simple to complex cells.
